I had this board for a while, had to replace the VGA connector because it just stripped away when removing the cable.

Was wondering if anyone had the latest Bios version.
Does anyone have a version with SDRAM? Any idea of the chip I could try to solder there?
Recap if you don't want to read the whole thing:
Supported cpus:
PIII :Coppermine up to max (tested), no Tualatin;
C3: up to Samuel2 core (all tested worked).
Celeron: Mendocino (333 to 533) + Coppermine (up to max, 1100)
About the SDRAM sockets:
they come unpopulatated (TSOP-II 86 pins) and you can only use "shared" memory for the onboard TNT2; max 32MB.
If soldered, the two SDRAM chips are recognized and used, but in BIOS shared memory must be set to "none" (0 MB) to work.
Local buffer memory used shows at POST.
I couldn't make 3D tests because I failed soldering the two chips and many traces got damaged, but it does work.
Micro soldering is difficult, you need a microscope and good skill, also the working area isn't very large.
I was partially successful with 16 MB, but I think that 32 is feasible.
Video ram speed depends heavily on Bus speed.
