I have this 486 motherboard that just won't boot. I got it with all the jumpers removed so I tried to set it up by looking at a photo of a similar revision board I found on-line. Not all jumpers match tho and the board has no battery atm. Any suggestions?
At first glance, it doesn't appear that there is a voltage regulator on-board. So, you can only install 5V CPU's.

Yeah, there isn't one. I tried to test it with a 5V DX2-66 but only got a black screen. I'll see, if I can find the board on the website you linked. Thanks.
its a shuttle HOT-419.

More specifically a Shuttle HOT-419 VZ. There are other revisions like the R1/RZ, it is almost identical to VZ expect it has extra 4x30pin memory slots. Then the R2 sports a voltage regulator, and R3 has Cyrix/AMD 5x86 support as well.
Here is the jumper settings for version VZ: https://www.shuttle.eu/_archive/older/de/419v … tm#konfiguratio
Just to make things clear, the motherboard came with NO jumpers installed at all. Zero. So, I need to know where everything goes, not just CPU, FSB, cache, etc. I see that the Stason website has most of those listed... will try my luck tomorrow.
EDIT: after inspecting the board again, I found what seems to be a destroyed jumper header on the left side of the CPU socket. Some of the chipset pins also appear to be shorted, at least one is broken and several appear damaged/mangled. I don't have the equipment to fix this but the rest of the board seems fine at least cosmetically.

Let me know if you need jumper settings that is not documented, I can check them on mine.

Probably why all jumpers were removed. Someone thought the board is beyond repair and took all the jumpers for spare.
