You may have to pull the chip and program it using an external programmer. Sounds like ti could have gone bad, and indeed a bad BIOS is a fairly common voodoo failure point - for example see https://www.youtube.com/c/vswitchzero - he has videos around troubleshooting this kind of issue.

I love a good 1997 build. Those poor little machines may have had the least staying power of any. You were stuck between a Pentium 233 MMX machine with probably a Riva 128 and an AWE64 with 32 MB of RAM that might retail with all the accoutrements for $2500. Or you could go big on a Pentium II 300 …

Looks similar to this maybe: http://www.win3x.org/uh19/motherboard/show/7209 [doesn't seem to help much, as can't find any more information about it. What jumper settings are you missing?] Thanks! That appears to be it. To be honest, none in particular - the main ones are silkscreened. But there's …

I'd like to find the manual / jumper settings for this board. There's some on the silkscreen but some aren't described. This chipset seems common on dual 386/486 boards but this is a straight up 486 board. https://i.postimg.cc/MT4YqhKk/182745182-10158955941393376-512677951023617509-n.jpg It's marked …

So I fixed it.. Turns out although the board is marked as a J-542B, when you examine the silkscreen further and the manuals for both the J-542A and J-542B it is clear this board is actually a J-542A! Flashing the A BIOS resolved the corrupted screen. bizzare but probably typical of boards of the era …

How does it look when you enter the BIOS? How does it look when booting from DOS floppy (I see a floppy disk error, why ? What CPU and are you overclocking ? Fine, as is the secondary BIOS summary screen. I can boot into DOS. It's a K6-2 500, no O/C, I've tried other CPU's too. The floppy error was …

I have this board, Super Socket 7, Jetway J-542B, that behaves weirdly on the POST/BIOS screen. The top half of the display is always corrupted. Other than that it seems to post. I've swapped out PSU, RAM and tried graphics cards in AGP, PCI and ISA but issue always remains. I've also tried using a …

Hi! Can you upload the drivers for REVEAL / SOUND FX WAVE (SC500)? I've just bought this which seems identical to yours, but can't seem to find the precise drivers online.
