    Default Need help identifying 386/40 motherboard

    I just got this 386/40 computer and would like to know the manufacturer of the motherboard. I suspect it is an American Megatrends 386 motherboard.

    It has MB-1333/40 MKA-F Ver:2 printed on it. The BIOS ID string is 30-200-001223-00101111-111192-MXIC-F and the model shows as MB-1340MKA-F on the post screen. The closest match I get is a MB-1333/40 AEQ-K/AEG-K which is an American Megatrends 386 motherboard. Any help would be appreciated.

    So far I have been able to determine this is a Biostar motherboard with a MACRONIX MX83C305FC/MX83C306FC chipset. The chipset has an integrate 8K L1 Cache. Very interesting board the more I look into it. I can't find really much information on the chipset. If anyone knows where to locate the technical docs for it, that would be appreciated.

    I found that one on stason.org as well, but unfortunately they are not the same boards. My does not have any cache memory except for the 8K built into the chipset.
