Hi, two weeks ago I was wondering in a local flea market when I found a little and cheap motherboard (5 euros). ECS P6VEM3 is her name.
After some cleaning it was time to test, first problem: the board didn't always booted, the fix was reflashing with the right BIOS, in the ECS support page for this board we can find 2 BIOS files, one for embed NIC and other for the models without NIC (mine dont have NIC) and it was flashed with the wrong BIOS file. Now the board always boot.
Second problem: the board didnt keep the BIOS settings when powered off. I replaced the coin cell but same thing, I have here some EPROM chips, found one similar and flashed again. Now it saves the settings.
For the case I have one that as offered to me by a good friend that is also an member here.
In my spare box I have found an 128 MB memory stick SDRAM 133 Mhz to match the frequency of the C3 chip (1 GIGA PRO @ 733Mhz).
For storage an old PATA 160GB hard disk.
For sound I found in my magical spares box an YMF724 bought some years ago for 2 euros.

My main goal is an flexible W98/DOS machine going from 386, 486 and Pentium class, so why not enjoy some 3DFX capable titles? Once again magic spare box to the rescue and I found a Voodoo1 card.

Using SETMUL the result is outstanding. Some pics now
