I have this same problem on my Compaq Presario. I think that this is because the BIOS was shadowed and used some writable-RAM somewhere. Linux seems to do a 'warm-boot'. The result being that some of the stuff that the BIOS counts on was wiped out by Linux, i.e., stuff from E000:0000 -> E000:FFFF (the BIOS is normally at F000:0000).
My 'fix' is to cold-boot, i.e., processor reset during the shutdown.
Cheers, Dick Johnson
Penguin : Linux version 2.4.18 on an i686 machine (797.90 BogoMips).
Windows-2000/Professional isn't.
