The problem:
My Iwill P55XUW TX chipset motherboard (SCSI disabled in BIOS) reboots
after these messages
...
...
Probing PCI hardware <... something ..>
Calibrating delay loop <... something ....>
Then it reboots, and repeats the same thing.
My question:
The IDE disk that I boot from boots ok in an other maskin.
What puzzels my is that I can't see anything written in
/var/adm/messages or syslog from the failed boot when it rebooted. Isn't
he supposed to write back to those files during the boot process ?
Is this why it keep rebooting becource he can't write to disk ?
I've tryed booting whith RedHat boot disk and Slackware bare.i.
Also compiled 2.0.33 whith pathes like
pci-conf2, pci-reboot, pci-sanity-check and reload.
No modules.
Please help.
