Hello,
I've recently decided to build a dream 486 machine but I am having issues with the motherboard. I was hoping for some ideas for testing that I may not have thought about. The board was apparently tested (and working) according to the ebay seller but it seems DOA. The board does not POST nor does it beep at all, even without RAM installed (I should get a long beep without RAM). After configuring the jumpers according to the documents I have for this board, testing the power supply (which was new), swapped out the CPU, removed the ram, I am still not getting any beeps from the PC speaker nor video signal using an S3 ViRGE 2MB. Also double-checked the PC speaker connection and swapped it out for a tested one as well.
System specs:
Motherboard: M-Tech R418W2
CPU: Intel A80486DX-33 SX419
Cache: 256KB 32x8
RAM: The board came with 4 FPM SIMMs but I have EDO sticks as well. I have tried them all. (But not the EDO and the FPM at the same time, of course.)
PSU: AT 300W
The motherboard documentation I have been using is located here: http://motherboards.mbarron.net/models/486pci/r418v2.html
Is there anything else that I can try? At this point I'm pretty sure its a dead board but I'd like a second opinion.
