Thread: Anyone have the BIOS for a PCI54ST-1?

  1. #1

    Default Anyone have the BIOS for a PCI54ST-1?

    Recently pulled this out of a box, in 2004 the system stopped booting, I didn't have much equipment at that time so I boxed a load of stuff up for the future, most of which has since been fixed. It appears the EEPROM containing the BIOS has failed, can't read anything from it if I place it in another machine; instead of hot-flashing, I was trying to "hot-dump" - sounds wrong on so many levels - the BIOS to check it's integrity, results in claiming an Unknown EEPROM type and no data is readable. I believe the system had Award Bios but the only info on the top of the EEPROM is two letters "H.T." - heh, my initials.

    TMC Research Corporation - PCI54ST

    Ex-military. Uses SiS 5511, 5512 and 5513 chipsets.
    Socket 7 Pentium up to 150MHz.
    Weird board, only Socket 7 I have seen with barrel battery (removed).

    Wondering if anyone has the BIOS, can dump the BIOS or knows of one that may be compatible - presumably some very similar motherboard might work, I have a few EEPROMs spare.

    Edit: By all means make fun of my oversized feet (seems my boot is in the bottom of the first image).

    DOSBox sucks, my Casio is better than your Roland and my clone is better than your overblown proprietary box.

    Not Sure, but give it a good try.

    Here are 3 from Asus that use the 5511 chipset, use due diligence prior to experimenting.

    And here are a pile more from Asus that have possibillhillies.

    Couldn't locate the original. As a matter of fact, the old TMC website via the wayback machine doesn't even list that board.

    Final edit, If you do try one of the Asus BIOS, the P/I-P55SP4 ( )
    seems closest to your board.

    If you send me a PM with your e-mail adress, then i will send it to you.
