If you are looking to buy those nice dc7700 desktops be advised that they don't boot any of the well known linux distros.
They don't run Redhat RHEL4, RHEL5beta2, Fedora Core 6, Fedora Core 5, Fedora Core 4, Ubuntu 6.10, ...
All the reported suggestions like
acpi=off pci=nommconf all-generic-ide jusjavascript:postMessageSubmit('submit');t don't work.
HP Official phone support does not want to open a case as linux is not a supported platform.

Hello kiwi!
This message is the same i have with an old Ibm GL300.
The problem was the ram.
Can you try to launch Knoppix - Live?
Knoppix 4.0.2 was the only distro start on my machine. Then i changed the ram.
Try to start knoppinx and see.

I know the pain.
Fortunatly, I've solved the problem with Debian GNU/Linux and some heavy alternate installing.
The whole problem boils down to the linux kernel not having support for all the neat Intel/HP hardware.
Linux kernel 2.6.19 (released a few days ago) *does* support all the hardware (minus ACPI).
You can get the kernel config I use for building the kernel here:
http://www.sron.nl/~mverwijs/files/2.6.19-rc6-desktops
The way to install Linux on this DC7700 is a pain, but so was the DC7600 when it was first released.
Back then, I wrote a dirty script that I ran from Knoppix. Basically, it did:
Knoppix Method (< DC7700):
==========================
1. boot knoppix
2. format disks
3. use debootstrap to install Debian on the harddrive
4. put my own kernel on the harddrive
5. install grub, pointing to the new kernel on the harddrive
6. reboot
7. profit!
* The Knoppix method will work on DC7700 when Knopper releases a knoppix cd with 2.6.19 kernels.
But, with the dc7700, I can't get Knoppix to boot. So, I now use PXE!
PXE Method:
===========
1. Boot over pxe+tftp using my 2.6.19 kernel
2. Mount / via nfs on a nfs server
3. format the disk on the client
4. install Debian using debootstrap
5. install 2.6.19 on harddisk
6. install grub
7. ....
8. Profit!
PXE is very scalable. And next time there's a new batch of DC9999's coming, I'll just replace the 2.6.19 kernel with the 2.6.51 kernel that'll be out by then.
Alternative method:
==================
1. get disk out of dc7700
2. place disk in older model
3. install debian
4. boot into debian on older model
5. apt-get install kernel-package
6. get kernel source from kernel.org
7. build 2.6.19 kernel with my config
8. place kernel in /boot, update-grub, reboot
9. check everything is in working order
10. remove disk from older model and place in dc7700
11. ...
12. Profit!
Ah... the Joy of Debian! |

What about this method?
1. Take the hard disk out of the DC7700 and place it in another PC, one which boots Linux fine
2. Install Linux
3. Build your own Linux kernel, if needed (I do not fully understand if the problem is only with Linux not booting for the installation, or not booting at all once installed too)
4. Take the hard disk and place it again in the DC7700
While Windows needs to install in the exact machine you are going to use it, Linux does not take into consideration most of the differences in the systems thanks to the initrd system. The only detail you need to pay attention to is the kernel: make sure you install an i486/i586 kernel if your machine does not support amd64 instructions. |

The only problem I have with taking the harddisk out is that is does not scale.
I have to install Linux on about 20 new machines per year. And I'm lazy. ;-) |

If you can live without ACPI, just disable it. At the boot loader for Fedora/RedHat add acpi=off to loader line.
For example
#linux acpi=off
or
#text acpi=off
This disables ACPI support in the kernel. When RedHat or Fedora installs, it will keep the same the option on the grub.conf loader line. |

After trying various distros I finally got Debian to install using the latest netinstall cd.
My problem now is that whatever I try, I can't get sound. It looks like it's working, with modules loaded, and songs playing in various software, but no sound coming from the speakers. It works ok in windows, so it's not a hardware problem.
Any tips? |

a simple Red Hat 7.3 is able to boot and install on DC7700, no sound, usb, lan and only vesa video after the installation, but it is capable so a new distrib must be ok.

Hello,
I just installed CentOS 4.4 x86_64 (kernel 2.6.9) on a DC7700p (RN123T). The onboard NIC however does not work with this kernel, you 'll need to compile a new one as mentioned by 'afz'.
I also changed a setting in the BIOS:
Storage > Storage Options > SATA Emulation = RAID
This setting will enable the harddrive DMA mode (/dev/sda). Check this with 'hdparm"
# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 180 MB in 3.02 seconds = 59.59 MB/sec

In response also to the folks coming from the UK news site the Inquirer
http://uk.theinquirer.net/?article=37136
As the original author of this thread I have spend hours and hours getting some sort of acknowledgment that there is a problem with the DC7700 hardware from HP.
After getting the funniest responses from the HP phone support , variations on , 'well yes you have to ask Microsoft for SATA drivers for Linux', 'Linux is that a new game ?' I got terminated with the 'linux is not supported on this platform'.
Funny thing is that you can order the DC7700 desktops without a Windows license, and then they comes with Freedos installed and a piece of paper about the limited use of Freedos and a pointer to linux.
Seems all a bit silly that HP brings out a business line of desktops for their business customers, then goes around Europe with a Linux Roadshow
http://www.hplinuxroadshow.com/ but does not even validate that their business machines can be booted or installed using a few enterprise linux distributions.
Don't get me wrong : It would be great if HP would bring out drivers and give support like they do for Vista but I would be glad to have a business machine where you could pop in a Red Hat CD and have it actually installing.
But the DC 7700 desktops hang without the acpi=off parameter and when you use this parameter the installation takes hours and the machines feel like Pentium II 300 Mhz machines. The workarounds suggested above are appreciated but not scalable and I'm still awaiting some response from HP.
With bios version 1.09 Rev. A (11 Jan 2007) that came out to support Vista I was finally able to get a RHEL5beta2 installed on this Core 2 Duo 6600 machine with the acpi=off parameter and with a more reasonable speed (comparable with a Pentium 4 2 Mhz)
Still a long way from the speed of a Core 2 Duo 6600. So if you are a business customer wanting to try out Linux on the Desktop, stay away from HP until the company takes Linux seriously enough to validate a response. |

Hi Kiwi,
I think we need to be consistant on what we are asking.
I do agree that it is normal to be able to by PCs with no os preinstalled.
HP sells PC with
-windows
-linux
-no os, just freedos
Those PC are supported accordingly.
Support an os on a platform has a cost. If you buy a PC with no os you rely on the community to adapt the os to that platform.
And there is no doubts that into some weeks that platform will be supported under linux.
But I don't see how you can buy butter and keep the money.
Even Redhat and suse support are not free.
Debian support is free and is working on
it with some work.
If HP certify the PC on linux distribs, it cost money. Are you ready to pay more for that?
If you want a pc certified with linux, buy one which is sold as certified under linux.
Else just turn up sleeve, and work.
I think we must get rid of the impression that free os is free of charges, and that work is for free.
I want my PC to be certified, I pay for it.
HP sells PC certified under linux! |

Hello Arthur,
Thanks again for your remarks.
I think we are very clear on what we are asking from HP.
Ideally I want to be able to buy and recommend HP business desktops with Linux preinstalled but I challenge you to find a machine that comes preinstalled with Linux in the price list. http://www.hp.be/pricelists/pdf/business_desktops.pdf
You just can't buy a HP business desktop machine with a preinstalled linux and you can't order build-to-order units with Linux installed unless the amount of machines is huge.
I'm stating here that I want to pay for a preinstalled Linux OS, and I would even pay the same amount for a preinstalled Linux as for a that installed XP license.
Lacking the option of buying a preinstalled Linux, the next best thing is to order a model with FreeDos and install the OS yourself.
Our problem is that the DC7700 can't be installed with Linux on any conventional, easy way due to both a broken ACPI support in the bios and incompatible hardware.
Bringing out a mainstream business desktop for the enterprise customer in 2006 that does not allow a enterprise linux distribution to be installed does not cut it.
There is a huge hap between the HP 'marketing and communication messages' around their support and commitment to Linux and the reality in the field.
Where can I buy that business desktop with Linux ?
Why does HP wave the Linux flag and then brings out their new mainstream desktop platform that is incompatible with Linux. Where are those supposedly close ties with Linux distributors and why did HP not cooperate with them so to make their platform compatible ?
I'm stating that I want to buy those Linux desktops and want to buy those Linux support contacts but HP does not want to take my money ?
None of the currently available desktops is certified to work with Linux:

Using pci=conf1 passed to the kernel I successfully managed to install and also boot Redhat AS 4 Update 3 as well. (On Bios version 1.05 though I have since taken the liberty to go to 1.09a) Out of curiosity though what are the "side effects" of using that parameter? Hardware detection loss etc? The parameter also works with a boot up of knoppix 5.1.1 as well when i tested. |

I took delivery of a dc7700 demo unit on Friday
Jan 26. It came preinstalled with winXP and 1 gig ram.
I grabbed my openSUSE 10.2 x86 32 bit installation CD's and booted acpi=off and proceeded to the installation. The process included shinking the installed winXP NTFS partition and creating new partitions and filesystems (ext3) for the OS. The installation went very smoothly. The only thing that did not work out of the box was the intergrated sound however switching to alsa sound architecture
fixed that problem. I had a fully functional dualboot dc7700 winXP/SUSE10.2 within 1 hour of
first powerup. I then used vmware workstation 5.5 and created a new winXP virtual machine.
Both the linux host and virtual winXP client
performed very simultaneosly. One of our bench mark test suites to determine system performance is matlab bench which performs several operations to determine harware performance and compares to other hardware platforms. I tested both the virtual winXP virtual machine and the linux host performance and the dc7700 outperformed many other high end hardware kits.

I also performed a number of hdparm tests
on various disk devices and disk IO performance was comparable or better than
any other pc's I am currently running linux on.
This morning (Jan 29) I was pleasantly surprised when I loading my dreamlinux live CD and booted with acpi=off
After choosing a proper video res for my current LCD and configuring my network settings (rightclick desktop/Settings/Network settings.) I had a fully functional linux OS
running live from CD with all system devices
detected and working (including sound!)
http://www.dreamlinux.com.br/english/download.html
dreamlinux is based on debian
uname
Linux Morphix 2.6.18.1-kanotix-1 #1 SMP PREEMPT Wed Nov 29 15:15:15 EST 2006 i686 GNU/Linux
I will be performing many more tests with other alternative OS's over the course of this week but if what I have seen so far is any indication of the potential for the dc7700 and alternative OS's I would have no reservations in suggesting that this hardware kit up to the task of being certified for any current linux distribution. |

I had success installing Fedora 6 with
the following kernel parameters:
acpi=off hda=noprobe hdc=noprobe
After installation "hda=noprobe hdc=noprobe"
needs to be added to /boot/grub/grub.conf.
Without this, the IO performance will be
very bad.
However, after upgrading to a 2.6.19 kernel
it doesn't boot anymore, so don't use a
respin'ed FC6 to do the installation.
BIOS 1.09A makes no difference.
Both the i386 and x86_64 version of FC6
work.
I've also tried the i386 xen kernel and
have installed w2k and wxp as fully
virtualized guests.
The virtualization needs to be enabled
in the BIOS.
I do have some problems with the NIC,
it looses connection at gigabit, I had
to connect the NIC to a 100Mbit switch.
This occurs both in i386 and x86_64,
with or without xen. |

One funny thing:
I've tried booting the HP Insight Diagnostics,
version 7.7.0 A on this machine (this
CD is Linuxbased).
It doesn't!
If I raise loglevel to 9, I get the usual
kernel messages during boot, and it hangs
at the same place as my Fedora boot:
ACPI: Assume root bridge [\_SB_.PCI0] bus is 0
I can boot the CD if I add acpi=off
So the machine fails diagnostics :-) |

Shalom,
Its pretty clear Linux should NOT be used on this box.
If you want support you should probably contact HP and demand it. This is typical of entry level HP computers though its mostly laptops with this problem that I've seen in ITRC.
Truth in advertising there is nothing on the HP website saying anything different.
Before you buy, look for the penguin.

i think pci=1 should change the irq routing, which would appear reasonable.
I'll save You the rant over broken BIOSses being delivered. But I can't share the 'support' reasoning at all - if You buy a PC You should get a PC that adheres to standards to some extent. |

My dc7700 is running SuSE 10.1 very well
The installation was smooth. I used the boot CD to perform a resize of the NTFS partition, repartition the disk and finally install on new partitions.
The only issue is with the sound system. but this seems to be fixed by using ALSA.
To be honnest I must add that neither knoppix nor gparted were able to boot. Both distro had a kernel hang-up during the PCI probe step. Fixed with SuSE :-) |

Would someone who got the sound to work with the DC7700 and Linux using ALSA care to share how they did it? I'm running SuSE Enterprise Linux Desktop 10.1 and I haven't been able to get the sound to work. Other than that, it has been running flawlessly using the acpi settings previously mentioned in this thread.

Nancy,
You have reached the team who specializes in addressing Linux problems
raised by customers who write to HP. I am a program manager and
experienced software engineer, not a helpdesk responder.
I have been investigating this issue and obtained the following
information from my contact from the dc7700 product group.
When Red Hat releases RHEL 5.0, the dc7700 will not be certified, but
it will install on the machine. There are some visible bugs which you
can work around. These are:
1. RHEL 5.0 will only install if the kernel flag 'acpi=off' is
supplied at boot time (either by the user, or permanently set in
/etc/grub.conf)
2. The accelerated graphics driver from Intel has a serious bug which
causes the display to become unreadable if you switch to a tty.
If this happens, the only remedy is to reboot the machine. If you
change your video driver to vesa, the situation is a bit better
because you can fix the problem simply by bringing the machine
down to runlevel 3 and then back up to runlevel 5. It's best if
you never switch to a standard tty to begin with.
3. Audio plays only out of the front jacks. This should be fixed in
the next version of ALSA (1.0.14rc3) but you would have add that
to the system on your own.
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1081719
also has some information about Linux on the dc7700 that you might
find useful. (Try booting with "pci=conf1".)
If I have not addressed your concerns, you can reply to this message
and our Linux team at oslo.helpcustomers@lists.hp.com will make an
effort to assist you. Please understand that because Red Hat will not
be certified on the dc7700, your configuration is not officially
supported by HP. Therefore, we can only make a "best effort" to
help. I regret the imprecision of David's choice of words.

Hi,
I have the same problem on a fresh DC7700pC with :
- Processeur Intel Core 2 Duo E6300
- Chipset Intel 965Q Express
- LAN Intel 82566DM Gigabit
I understand than Maarten Verwijs said that kernel 'must' be at least '2.6.19' to work on.
He said also "The Knoppix method will work on DC7700 when Knopper releases a knoppix cd with 2.6.19 kernels"
Now, the Knoppix 5.1.1 has kernel 2.6.19.1
Must I use the 'all' method, or it is a simplest way to obtain a basic linux box (any distro) to act as devel server (ie. install Knoppix on HD) ?
I have tried only Centos 4.3 and RHEL 4.0 at this time and search for distro with 2.6.19+ kernel 'in case of ...'; any suggestion ?
Thank |

I'm running DC7700 with Linux since December. To be honest it was hell to setup the machine for the first time.
The only difficulty I had was the limitation of only 1Gb RAM. This is solved with bios version 2.09.
I've customized the FreeDOS image and aded the MEFlash program and the DOSFlash program.
If you want to run MEFlash under Freedos you have to run Freedos without himem.sys and emm386.
Currently I run the 2.6.20.1 kernel with ACPI at kernel level disabled.
A basic configurationfile of the 2.6.20.1 kernel is attached. |

Hi everybody,
I have at work several machines like this. We tried using RedHat 4 Enterprise with no success. Fedora 6 worked with the already known workarounds like pci=nommconf, but it still had strange problems related to Video Graphic Adapter and Network. We got strange small hiccups if I ran glxgears, but If I have restarted the network daemon it was working correctly.
With Fedora 7 it installed ok, but the problems continues. Same hiccups with Video driver (even if it has the intel proprietary now), but now if I restart the network, the keyboard won't work.
My conclusion is that there are weird conflicts on hardware sharing, and I was not able to fix them. Sometimes unloading the e1000 driver and replacing it with e100 driver seems to work.
With the latest xorg updates from today, I don't have any hiccups in the system, but the graphics adapter still has problems.
We are going to change these machines with something else next week. It's ashame. |

After the latest updates from in F7 I don't have any more interrupts when moving the mouse on the screen.
More, I have found a way to make glxgears (opengl applications to run without interruptions).
- service network stop
- rmmod e1000
- modprobe e100
- service network stop
It seems that somehow the e1000 driver is having a conflict with the video adapter. Removing it and using e100 solves the problem.
Good luck |

Some Linux distributions OpenSUse 10.2 have a problem partitioning hard drive because some dc7700p systems have two hard-drives in RAID configuration. Installation fails. So, do not buy any configuration that has RAID config.
You can go to BIOS and disable RAID and attempt to install Linux on the second hard-drive. OpenSUSE 10.2 partitioning process still fails. The partitioning seems alright, but I think the failure occurs when the file system gets created.
You can install by having only one hard-drive in the entire system. Unplug the Windows hard-drives.
Intel Q965/Q963 driver does not work in Linux. If you only want 1280x1024 configuration in Linux, this is no problem because it uses frame-buffers and not the graphics adapter itself (basically Q965 is useless). You have to buy some other video card to get higher resolutions.
Bottomline: If you want to run Linux, this system not a good choice. There are many other machines or vendors that offer a much smoother solutions for Linux. If you want to dual-boot with Windows, this machine is next to useless. You never know if the future Linux versions will be compatible with the hardware.
Going forward, there will be no more HP system purchases from me for my business if I need to run Linux or dual-boot. For such systems, I am going to a vendor that sells Linux preinstalled (OpenSuse specifically). Certification is not enough. I would like full pre-installation and full business-class support. |

A few remarks:
support for hdparm is since the 2.0 kernel.
Then the previous poster. I absolutly don't agree with you about the poor support of OpenSuse with de DC7700. Most software raids work poor in linux (not only driver-support but also performance) Therefor are good alternatives.
I installed at about 20+ DC7700 machines with Linux and I only had to put off ACPI (which I post before).
Kind regards,
Gerjan |

Well Gerjan,
You might want to share your secrets in detail.
When we contacted HP Israel about Linux and the dc7700 system, their response was to tell us to buy another platform.
The dc7700 has no HP support for running Linux. Nor does Red Hat support his platform.
I reiterate my earlier commentary which is to not use Red Hat or any other Linux on this hardware until HP provides offical support. That is Corporate policy where I work as well.

We have a bundle of these dc7700p machines here running ubuntu.
We've had nothing but problems (slow, glitches, crashes) UNTIL we updated the bios to v2.10.
Just testing now but it is screaming along now. Havent tested sound or anything yet tho.
Regards. |

Machine: dc7700 with E6600 + 4G/667 + nvidia nvs285 + 2x80G Hard disk.
(don't ask me why I have this setup. If I had a choice I wouldn't touch branded pc's with a 1 mile stick).
I have had this machine for a couple weeks now and successfully installed FC6 on it (initially 2.6.18 and was updated to 2.6.21).
It was working quite happily. A couple of nights ago I shut it down, and the next morning nothing was coming up.
I had disabled the yum updater in case you want to know, so nothing was updated behind .
I have winxp there as well.
A couple of symptoms that I have noticed.
1- After Pressing F9/F10 it takes almost exactly one minute for the menus to appear.
2- When doing memory test the first 3584MB of testing goes relatively quickly, but then suddenly it slows down by around a factor of around ten. But the memory test doesn't report any problems!
3- The diagnostic tool passes all hardware. However, it does not list the two hard disks.
4- When I run the "linux rescue" from the dvd I can actually see all my partitions and have been to run fsck on all of them, and they are clean. I have also rewritten the MBR from grub command line.
I had an online chat with an itrc guy, but it was expectedly fruitless.
Has any one seen a similar problem?
Thanks |

More info.
After about two or three minutes, the system comes up with the "non-system disk or disk error" and stops there.
It is from here on that I can use my hp diagnostic cd or FC dvd. |

update:
I reinstalled linux (only as much needed to get a system up). The install went fine, but the problem still persists, i.e. it comes up wih "non-system disk or disk error"
It should now have a fresh MBR, and /boot.
I appreciate any ideas that might shed some light on this.
I probably should mentions that I refreshed the bios at 1.10. |

amx,
You are not the author of this thread. At least I think not.
You need to write your own question so that if someone provides you a useful answer you can be a good ITRC community member and award points.
Bottom line here has not changed. You CAN NOT use this system effectively with Linux. time to move on.

SEP,
No I am not the author. But I really want to get the problem solved.
This thread seemed like the closest match.
Whether in general dc7700 is having problems with linux, it does not change things.
It would be in everyone's interest to know what is causing it, and how to avoid and even better solve it.
So far the acpi has been identified as a source of the problem, but not in my case.
amx |

Open your own thread. That is the way it works in ITRC. No help from me at least until you open your own thread. Link this thread in.
As I mentioned this system does not do Linux. You can add your own NIC card and then it will do Linux. No more help from me until you open your own thread.

Update:
The whole problem was caused by a dead hard disk, where the winxp was located. The bios was pretty hopeless in identifying that, so was the hp diagnostic tool.
Everything had to be reinstalled.
I have installed FC6 and did the latest updtes, and it is working well.
So I guess dc7700 CAN do linux.

Shalom and congrats.
I'm glad it works for you amx.
Two issues.
1) Its not supported. If you have a problem HP probably won't help.
2) I don't understand why you can't follow the guidelines of the itrc community. You don't hijack other peoples threads and ask for help. Fittingly you got no help and figured it out yourself. ITRC works as follows. You write your own question and you reward the help you receive with point assignment.
I have yet to run into someone as hardheaded as you amx. That helped you fix your problem and takes you outside the community of ITRC.
Take a note from the original question.
HP Official phone support does not want to open a case as linux is not a supported platform.
LOL.

We have a new HP dc7700p and can install RHEL 4 and 5 OK but there is no network support for the Intel e1000 network card. Thus the network drivers had to be loaded manually.
The problem is that we are using network kick-start process rather than a direct DVD installation, so that we can get a custom LINUX configuration for our organisation with custom applications etc.... I have been reading about making a driver disk via kick-start but no luck yet.
I notice that the dc7700 is not on the Linux Certified list.

I had good luck so far with RHEL 5 Desktop on the dc7700U (Ultraslim model).
Would not install initially so I did two things after reading these forums:
1)Updated the BIOS to the current version (786E1 BIOS) version 1.13 Rev.A, August 27, 2007.
2)Standard install failed still, so went into options right at the start and typed: "linux pci=conf1". This allowed me to start and complete the install.
System status: ethernet works fine.
Switching out and back into TTY7 fails, but can still swich back to another TTY.
Onboard sound does not produce sound.
So same results so far as has been described in these forums. I plan to investigate further with video and sound drivers. |
