Recently I got my hands on an IBM-brand 486 machine. The owner mistakenly installed WIN98 and now it can't boot; on startup it shows error code "1962". I've removed the hard drive and it's with me now.
This PC uses an IBM-specific BIOS, and I suspect it may be incompatible with operating systems other than PCDOS. So I downloaded a PCDOS boot disk from here, but it didn't work when I tried it. I figure maybe the version is too high, or there is some other reason. Could some expert point me in the right direction—am I correct in this guess or not? Which version of DOS would solve the problem?
One more question: I downloaded the four ZIP packages PCDOS1.10~PCDOS3.21 from the download area, and found that the files inside are all types I don't recognize, like *.izm and *.tdo. How are those used? Please explain.

Thanks in advance!

Then can boot disks for DOSes like MS-DOS, ROM-DOS, FreeDOS, etc. boot it?

MSDOS also can't boot. I haven't tried the others. I'm an outsider to DOS, I'll study more in the future.

On some IBM computers, the motherboard BIOS is on the hard drive. Could it be that you low-level formatted the hard drive?
