AT (or later) should have a CMOS backup battery - if not on the motherboard, then plugged into the board, probably near the clock crystal. > 6) ide is hot, like I said it will boot to C drive > > 7) swapped the ribbon > > 8) is th MOBO bad? well if it is, I have 2 that are the same "bad" This makes me very suspicious of a virus - which "protects" itself by disabling the floppy. Have you tried scanning the hard drive by plugging it into a working system? Be careful not to access the suspect drive, except to scan it. If a flashable BIOS is not write-protected, a virus can overwrite it, too. If that happened, you will need to replace the code on the BIOS chip, or replace the BIOS chip with one that holds the right code for your motherboard. > Ok I think I've covered everything.

Really old floppies had a removeable "chip" resistor pack (each resistor was about 150 Ohms). Only the A: drive on the end of the cable was supposed to have the "termination resistor pack" installed. The other, B: drive wasn't supposed to have one. Newer drives "compromise" by having a permanent resistor pack, with each resistor about 330 Ohms. The two 330 Ohm resistor packs are in parallel, and act like the original 150 Ohm resistor pack to prevent signal reflections on the cable. Although technically not as good as the original single resistor pack, the newer system where each drive has a resistor pack results in one less hassle to worry about. Have you checked the jumper settings on the floppy? The A: drive (on the end of the cable with a 10-to-16 twist. Check the cable - not all cables are floppy cables.) jumper should be set to the higher of DS1/DS0 or DS2/DS1 (not all manufacturers use the same convention). This, default, setting is actually B:, but the twist reverses it back to A: Boyd Ramsay [EMAIL PROTECTED] To unsubscribe from SURVPC send a message to [EMAIL PROTECTED] with unsubscribe SURVPC in the body of the message.
