    Default Intel "ZAPPA Expandable" mobo docs

    For $1, I collected a nice clean Intel Socket 5 baby-AT mobo with onboard I/O headers- see pic. I'm now waiting for a P1-100 CPU through the mail.

    The Intel AA number 647638-808 gets no result on Intel site or any of the docs resources that I know about. Chipset is 437FX.

    The nearest I have found is on TULARC, labelled ZAPPA EXPANDABLE DESKTOP (P54C-PCI TRITON).

    Everything is in the same place but my board seems a later revision - PS/2 mouse port, clock configurable to 50MHz, CR2302 battery holder - but cache absent (see the vacant SM sites top right).

    Any suggestions where I might find documentation for this board beyond what is on TULARC? The board is well labelled for configuration, but I would like to know as much as possible about the specs before firing it up.

    Its out of a Gateway 2000 system, the datecode sticker is a dead giveaway. Also known as the Intel Advanced/ZP and Advanced/ZE motherboard.

    This should be the latest BIOS (check last four digits when you bring the board up)

    Intel's manual for the Advanced/ZP: http://tulrich.com/tectrixvr/intel_p...995_manual.pdf

    Believe it or not, there is a MR BIOS release for this board (neat!): http://www.giffer.com/public/dos/pmu...s/MR_ZAP30.ZIP

    Brilliant - thanks! I knew this forum was better than G***gle.

    Wonder why this particular board was released with no L2 cache. Anyway, nobody selects a P1 for a permance platform, today.

    It comes from years of repairing computers. Its surprising to see a cache-less board from Gateway, it likely went onto a "cost reduced" Pentium 75 or something. It was quite common for the day with lower end Intel board OEMs like Packard Bell. They were able to mostly get away with it due to the Pentium's higher L1 cache, but there was still a performance hit.
