Booting problem with the old AMIBios.

[Danila]

Hi,
I'm trying to get my old Pentium-100 boot with Knoppix 3.9. I know that the chances to see the KDE are low, but I want to have at least the bash.
I have a TR2 (MS5120 V1) Mainboard from Microstar inside, after updating the BIOS to the last version, that was published the CD is at least trying to boot, but it stops with folowing error:

isolinux: Loading spec packet failed, trying to wing it...
isolinux: Extremely broken BIOS detected, last ditch attempt with drive = FF
isolinux: Disk error 01, AX = 422F, drive FF

Any suggestions how to get it working? with changed BIOS settings perhaps?
