ACPI with old bios can`t get work

[gkali]

Hello!

I`m running a Netfinity 3500 with ubuntu server jaunty.
My problem is that my BIOS is from 98 and it writes : it can`t be older than 2000 and i have to use acpi=force.
I gave grub a acpi=force but then it can`t load the root.
Loading, please wait...
// takes aprox. 30 secs
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay
- Check root
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/md0 does not exist. Dropping to a shell!

Thank you in advice!

had that happen - don't know the solution, but Arch Linux installed just fine on it.

actually, (if it helps) I _think_ the problem comes from missing kernel-drivers for long outdated hardware. For example I can't use my old sb awe64 under modern linux kernel: not supported anymore (at least by default).
