Unix cyl ovf please help

i have windows 98 installed in my computer and i'm trying to install unix sco 5.0.6 . i'm using partition magic to have both OS on the same computer.

The unix installation goes fine but when it's come to the point to give me the boot: it says CYL OVF.

I heard that is a bios problem .

Please can somebody tell how to fix this problem.

I really need help with this.

Jose thanks

BIOs errors need to be corrected by upgrading the BIOs or setting the appropriate flag in the BIOs (if one exists).

What BIOs and version are you running?

PhonenixBios 4.0. release 6.0
Bios revision GC.M1.63
S3 vga bios version 53.01
is a hp omnibook xe3

Neo you have no idea how long i've benn working with this computer.

Thanks a lot
