Diskless Client hangs on PCI Root Bridge

I'm trying to run a diskless client from notfred (CD version) on a HP/Compaq dc7800sC9 (Core2Quad 6600) but it always hangs with this line as the last on screen:

ACPI: PCI Root Bridge [PCI0] (0000:00)

Anybody got an idea what I can try to get around/past this? Much appreciated.

That's the kernel hanging during boot. Things I would check for are a new BIOS version and also see if there is an option in the BIOS to enable more ACPI stuff or disable it entirely. A newer kernel version may help - does it boot with an Ubuntu x86_64 live CD?

I'll try that thanks!

Your stuff is working like a charm using a tftp32 server at home ... PXE booting about 10 machines and folding like crazy :) you are my PPD hero 8)

hmm .. I've tried disabling the Power management in the bios but to no avail ... this problem seems to appear in other Linux distributions as well and the suggested option is to run the kernel with acpi=off parameter ..

Is there any way I can make this change? I must admit I'm a complete linux/unix nitwit so any pointers would be helpful ;)

You're going to have to unpack the .iso file, edit the file isolinux.cfg to add that parameter (to all 4 places would be best) where the other parameters are passed in, and then rebuild the .iso file. This should all be possible under Windows with the appropriate software, but I don't know what that software is, I use Linux only.

That's not hard to do ...

Do I add the ACPI parameter to the KERNEL line or the APPEND line? (sorry really don't know nothing about Linux :roll: )

I tried both with a USB stick (got tired of making coasters :wink: ) but no luck ...

This is what I'm trying at the moment:

LABEL fold
   KERNEL kernel32 acpi=off
   APPEND initrd=initrd USER=Sven.VdS TEAM=34517 BIG=big MEM= ADVMETHODS=yes SMPCPUS=2 BACKUP=15 REBOOT=enabled INSTALL=no BENCHMARK=no BLANK=0 SAMBA=2 GROUP=PXETEST PROXY_HOST= PROXY_PORT= PROXY_USER= PROXY_PASS= INTF= IP= MASK= GATEWAY= DNS= TFTP= SHELL=no


Is there an alternative syntax to do this? (or is mine wrong?) :(
