Arrrg. I've been meaning to open the cases.

Am quite sure I have all the other parameters (that are settable) back to the way I've always had them but I'm guessing there are values in the BBRAM for the BIOS that are used for setup but are not accessable from the provided user interface via any other means than "Load Defaults". I was using the settings as shipped from Atipa, plus a few little things such as selection of parity memory and reserving IRQ 5 and 10 for ISA cards.

Again, was in a friend's system that has the same cheapo MB this weekend and forgot to look. He purchased a 2.0G Ditto internal floppy tape drive and couldn't get it to work under DOS or Win95. Checking Iomega's web site I guessed his floppy controller on the MB wasn't "1 MHz or faster". Scrounged around here for cards with floppy controllers and the only thing that worked was the floppy port on an Adaptec 1542CF. He's borrowed it for now, but if I think too much about my 1542 spending the rest of its life as his floppy controller, I'd have to cry. Local dealers want $75 for Iomega's special floppy controller card. Ouch. WalMart's online shopper has it for $50.11, still "ouch". -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
