I bought an ATC-1425B 486 motherboard. It seems nice: PCI slots, EDO support, etc. The board was advertised a working with photographic evidence. It comes in the mail a few weeks ago. There's some surface corrosion on some of the metal parts and surfaces, including the simm clips, but nothing too bad it seems. Tonight I'm finally able to start messing with it. I find my correct CPU and voltage settings for the jumpers, install a known good Trident PCI VGA card and . . . .
1 Long Beep, 2 Short Beeps (AWARD Bios). Try another PCI slot. Same thing. Try the third PCI Slot. Same thing. I switch to a known good S3 Trio64 and then a known good TNT2 M64. Same thing, regardless of the slot I use.
Now I'm getting annoyed.
For some reason I decided to switch RAM around and try some different SIMMS. The simm clips are a little stiff due to the corrosion. I get the simms in. Now its one constant beep or no sound at all. I take a look at the SIMM slots. SIMM1 has bent pins.
What should I do? At a minimum, I'm going to need to replace one or more simm slots, but my soldering skills and equipment are mediocre. But, even then, I'm not sure what to do about the video card issue. Striking out with all three cards in all three slots makes me think there's something wrong with the board, but I don't have an ISA VGA card to test the board with.
