Interesting. Can you boot to floppy and then format the HD and then run
sys c: on it and then boot to the HD? Also try running fdisk and killing
all the partitions and recreating the primary.

Yeah, as a matter of fact I tried that.

I reset the CMOS and was able after that to access BIOS via F1. I set
the boot order to boot to CD, and now can load the OS from the CD.

Also try F12 and F10

Yeah I tried those. I guess the BIOS was just scrambled. I can access
it now.

Thanks for your interest.
