Greetings,
I would like to ask for advise on how to troubleshoot a motherboard to make sure that it is absolutely dead.
I recently purchased a 286 board.
For a couple of images with the memories taken out click here
There is nothing on the board to identify it, so I looked at stason and I found a pretty similar board (only difference is how the ISA slots are arranged?). It is a Peter 286 S?
So what I have already tried:
Fitted it with a PC speaker, an old Trident card, keyboard and a 200 W PSU. Tried with a 16 Mhz Harris and later with a 10 Mhz Intel processor. In both cases:
- I get NO beeps
- I get NO screen
- ALL the lights on the keyboard lit up and stay on, they don't go out.
After this, I've taken out all the on-board memory chips and put in 2 30pin 1 Mb SIMMs. Same result.
Tried it without a video card AND without a cpu. Same result: no beeps, no nothing, keyboard lights stay on.
Could you please tell me what I should try next?
