Do you have a copy of XP/2000 laying around? Just boot from the CD, format the drive when you are setting up windows, you can partition it there too, all the dirty stuff, do a full format with FAT32. After that finishes and you see the files being copied, cut the power. If you dont want to take the risk of damaging something, (yeah, right) then wait until the file copy finishes and the computer reboots, during POST, cut the power, which is not harmful. Then try your format C: function again, if it fails, try to install 98 anyway, maybe the format you did with XP/2000 will still work with it.
