So my replacement motherboard arrived and of course it has no documentation and I don't know what I need to setup jumper wise... a Micronics Socket 5 MB55061379 Motherboard.
All the Micronics motherboards I have include silk screened markings for each set of jumpers. I think you are reading the wrong label for the model number. http://stason.org/TULARC/pc/motherboards/mpent_6.html has a selection of Micronics boards and hopefully your board will work like one of the ones listed.
I was surprised to find an external battery connection on this board. It'll be so much better than my old Intel Plato board because of that... And this board has 5 instead of 4 ISA slots... So I have 2 ISA slots free if I ever want to add Roland MPU for MIDI output or other things. I had a brain fart and forgot that PCI cards screw in the opposite way that ISA cards do, so none of them are blocked.
Provide a picture of the RAM. Might be able to recognize one of those weird variations that only work with specialized hardware.
Common causes for working RAM failing would be dirty or broken SIMM sockets. Check those carefully. I know the documentation does not suggest it but some Micronics motherboards would work if RAM is placed in Bank 1 even if Bank 0 is left empty.
The ram looks new. And it's 2 8mb x36 ram which the documentation says to put them in bank 0 with the others empty. But I don't know if the ram is good and they cpus I was trying to use were bad or the CPU or the graphics card isn't working so nothing on scree, It could be a number of things. I'm getting fed up.
12 chip SIMMs are tricky beasts. Some used partially failed chips and relied on circuitry to only access the working sections.
I will try to open up my Micronics Pentium 90 and see what memory is currently installed. It is an PCI-EISA combined bus but I think the memory requirements were the same as your board. I won't be able to do it this weekend though.
Thanks for looking but I'm in the process of buying a working system for less than what it would to get my Gateway 2000 fixed. I'm putting this mess with behind me. This new system uses a CR2032 for CMOS data so I'm never going to have to worry about an RTC again.
