My cousin brought over his Compaq pc [winXP] which had a very bad virus, when I checked the HD was shot so I took a working HD out of my old Dell PII [win98] and placed it into the Compaq without changing anything in the BIOS only to get this message when booted up "No operating system found", I then took the HD out and put it back into the Dell pc where it came from and to my surpise got the same message there, someone told me this "this sounds like you have the CIH virus that overwrites the BIOS with garbage. It was on that drive you put in your other machine, and has now infected your other drive and possibly your other machines bios. It also wipes the hard drive(s). http://www.geocities.com/SiliconValley/Heights/3652/remove.html In this case the AVP antivirus program on a write protected floppy would be the tool of choice. As for flashing your bios, good luck with that. Shouldn't be too bad a problem for a compaq but if you got some cheapo motherboard, that may be an entirely different case. You'll have to look closely at the bios chip and get the right bios flash for it." So I went to the site in the link above and proceeded to follow it's instructions to get my old Dell pc up and running again with win98 but I think my first problem here before I can do so is that the only pc in my house that still has a floppy drive is my son's Dell PIII which has win2000 and from my reading up on OS and Bios e.t.c, it appears to me that I need to create the floppies on a pc that has win98? Can anyone advise me how to proceed from here please? Thanks.
