Wow Great of course most old boards will work if the MEM size is set larger than what is actually installed. Here is my edurcated guess for mem settings: JP1 : Parity, 1-2 = EN, 2-3 = DIS (is near BIOS chips) SW2: s1 thru s7 = size SW2: s8 = DRAM W/S (or speed). off = 70 - 120ns, on = 100 - 150ns …

Everything looks good. J7 is set correct. Are you sure you have the PS/2 port wired correct ? I have a pinout from Asus that shows their 6/8 pin PS2 port for most 486 and pentiums like this: 1 2 3 4 : 1 =Gnd, 2 = Data, 3 = NC, 4 =VCC, 5 = Clk, 8 =NC 0 0 0 0 0 - - 0 5 6 7 8

Good job FAMICOMASTER ! Think I would stick with the original BIOS until you get the KB thing figured out.

You can also leave as little RAM as you can and test single bank - if you stumble upon error - it contains bad chip - replace half of the chips with chips you removed... That is what I was going to suggest. Take all out but bank 0 and test, if passes then install bank 1 and test, etc. Also you …

Hopefully that will work, according to the manual for UM4981 AIO R2.1 the CMOS and RTC are located inside the UMC8498F main chip. You could also try shorting pins 2 & 3 on the ext. battery connector (with computer off and ext. battery disconected)..

checked a few manuals and the Shuttle HOT-553 has the Data and Clock (pins 1 and 5) swapped on the motherboard connector compared to the image Repo Man11 posted, the others pins are the same.

I can't find anything yet but can tell from your good pics that the board only supports 33Mhz 386 and has 32k cache. Comparing to the later rev on Stason.org would say with great confidence that SW1 is for cache size and SW2 is for ram size. It appears the cache is set to 32k and ram is set for 4Mb. …

Could be a supply issue. Do you have a digital voltmeter ? If so check the volts while it is connected to the motherboard and turned on. Should get the 5v 12v -5v and -12 v within +/- 0.2 volts on the main power connector. Here is the standard AT PSU pinout: http://www.minuszerodegrees.net/5150_5160 …

page 44 of the manual shows the CMOS clear jumper (J48). Are you sure the ram is good ? Have seen old boards report bad video card when the ram was the real issue. Also if trying an ISA card put it in one of the ISA/VLB slots or the ISA nearest the PSU power connectors.

I only have a single stick of ram. I did notice a couple caps with a slight bulge on the top and one that looks like it may have leaked a bit right next to the CPU, so I'm guessing bad mobo. Did you try the the one ram stick in all the mem slots ? Any bulge in a cap is a bad sign and any that …

NV20 is a Geforce 3. Probably a Geforce Ti-200 based on the fan and heatsink size. I see a part/board number in top right but can't make it out, can you take take a better "non angled" picture ?

Looking for a floppy drive in my boxed up junk stumbled on this Canon MD7511-C6 dual floppy so thought would give it a try. Works fine after cleaning and lube and thought would share some info: Make sure you set drive A=1.44Mb and B=1.2Mb in BIOS. Use the second (straight wired) floppy cable cable …
