As promised, nearly complete setup. Now running Windows Server 2000 as I had a copy in RAID 10 on a 3ware card (array of 4 x 8gb disks), installed the maximum 1gb of RAM and it is running the fastest P3's I could find which are 2 x 900mhz. Now since the picture, I have added a TP-Link WiFi card (TL- …

Wow, been a while, will post an proper update at some point. But: Been using the dual P3 board for various experiments, but it is currently running NT4 Server for a few experiments, so plan to do the following: 1) Keep running NT4 but find a multi-port RAID card and install some small disk modules …

I have picked up one of these boards, because it had 3 ISA slots and PS/2 mouse and keyboard connectivity and some 'modern' features. However, I did not see this thread though initially. My board is a Rev B1, so far I have been very lucky it would seem, I did find a manual for it though before …

Been a fun Sunday, dual p3 board has arrived and now have a front panel of sorts. Adding a sound card has been an absolute nightmare with these SBC's, despite what I do in the BIOS to assign the IRQ, it seems to make no difference. Only way I have found is to use the Intel Configuration Utility and …

Not much going on at the movement, making slow progress as I await various parts to arrive. Using the P4 SBC mostly, but not my favourite, it's PNP bus keeps taking over IRQ5 and 7 despite dedicating them to be ISA only in the BIOS, so the SB sound card is hit and miss at the moment. P4 now is using …

Few bits have arrived, let the fun begin The P4 SBC has 2.8 GHz chip and 1 Gig or RAM, thinking I will actually downgrade it a bit, find the slowest p4 I can and lower the RAM as much as possible. The Pentium overdrive on the other card is mine, was running a few tests. Prefer the P4 at the moment …

Another quick update. Been looking around and Ali Express seems to have a selection of SBC's which seem a fairly goodish price, so saved a bit of cash and been on a little shopping spree, on the way are: another P4 SBC Dual socket 370 I think a similar Microbus SBC to the one seen on eBay a new …

Quick update: Been testing all the PCI connectors on the board, the PCI slot behind the ISA slot is only connected to the other PCI slots for power GND, 12V (-/+), +5V, etc. The single PCI slots are correctly wired together, they connect to the reversed PCI above them, that PCI slot is correctly …

Maybe this was a solution to add a pci (graphics) card to an existing isa SBC [and extend the pci bus onto the board] before it was common to put the pci slot behind the isa slot on SBCs. The backplane shown seems to support both variants. when i follow the traces on the board it seems the weird …

these things are old PICMG standards for embeded/backplane stuff. search for picmg you will find loads of stuff. some backplanes were passive, some were active with pci controllers and stuff. Searched through lots of information on that beforehand for anything on the back to back pci slots, but no …

Well, with an PCI/ISA SBC in and configured to use PCI adapters, thought I would be able just to plug a PCI VGA card in (no VGA on my SBC board) and off I go, but no joy. The ISA slots all work so have VGA installed in that for the time, this is not going to be as easy as I thought, but then again …

Okay, now I am back from the school run, might have a lead on those strange back to back PCI slots, after trawling around the microbus website (who made the backplane) on the way back machine, various other backplane/SBC makers website with not joy, decided just to search eBay for Microbus products …

Bored of reading introductions? The question is at the bottom!

One of the boards has some potential …

This is pretty much as expected, part of me though was in hope someone might pop up and say, 'yes, I worked in the banking industry and we used MS-DOS 6.2x, and also still have copies of the disks'.
