I was recently given an AST 386SX/16 that is broken and I need suggestions on getting it repaired. My brother-in-law, who is not at all technical with computers, said that he had taken it somewhere to be looked at and that the diagnosis was "the mother-board is broken". What specific problem that encompasses I don't know. The AST has its processor on a peripheral card that plugs into both the AT-bus and another type of bus. I believe that this is a "feature" to allow users to easily upgrade the processor. Does anyone know if this card is what the repairman would refer to as the "motherboard" or does he mean the large board that contains the bus slots and built-in disk controllers? Any guesses as to how much a replacement AST386sx card (or better) costs these days? The computer is also lacking any floppy disk drives and the monitor was kept by the former owner. I had someone here at work take a quick look at the machine and we put a monitor and card into it to see how far it gets during power up. It successfully checks memory (1M) and then it prints out: INSTALLING SYSTEM BIOS IN SHADOW RAM and just sits there. It never accesses the hard drive or the floppy that we plugged in. Anybody want to guess what is giving it problems? We tried all the permutations of slots and cards and no difference. If anyone can suggest a fix, diagnosis, or let me know if there is any hope of this thing being resurrected, let me know. Otherwise, I may just part it out for pieces. If I can get this thing to work I will be in the market for a color monitor and controller card, and a floppy disk drive or two. This computer also came with no documentation. If anyone has a copy and would like to FAX me it, I would be eternally grateful. Patiently wondering.... -- Bruce T.
