Unfortunately I don't have any programmers and I don't really want to spend CAD $100 on something that I may only use a couple times. Thank you for the suggestion though! I understand. But I found a picture of this board, and there was a sticker on the Bios. Yours does not have it, so that is …

Unfortunately I don't have another CPU that will work in this board. This CPU was pulled from a working system. Before throwing the board away, check the bios. You need a EEPROM programmer, like a TL866II-Plus. Unfortunately I don't have any programmers and I don't really want to spend CAD $100 on …

Glued 6 small heatsinks on the top. Does it now run at 33 or 83MHz? 33MHz, I try to short the GND dot and Sensor dot with a wire, but it failed to boot. Any way to work around to get 83MHz back? Thanks. I guess it ran then at 83MHz when it failed to boot. It might simply be broken, maybe it was run …

I'm having trouble trying to upgrade the RAM on my DELL 425s/L According to the manual the machine should take up to 64MB RAM. I am forever stuck with 03360K RAM no matter what sticks I try, its either that or the machine wont post. When I got the machine it came with a stick of 8MB EDO RAM but the …

I've just learned that Windows 98SE won't install on a 386 - the minimum is 486. Any idea why? Is this just artificial limitation, so that nobody complains that it runs sluggish on a 386 ? Or it actually uses 486 instructions somewhere? Is it possible to make it run on a 386 via some patch, perhaps …

I had Windows 98se running on 8mb ram with a 386, the mouse cursor would hop around and freeze any time there was some sort of activity 8MB is not enough for Windows 98SE. Even with a faster Pentium CPU. You should have done the test with 32MB RAM for example. EDIT: The video above is like that, …

Done. Finally I got some bloody W29EE011-15 chips. Of course I had to try the 2800 Bios immediately. What shall I say? It works much better with a 1Mb chip.

Really exciting! The Pentium OverDrive 83MHz works! Is this a modified Pentium Overdrive? Without fan normally it will run only on 33MHz, so with multiplier 1. That would be slower than a DX2-66, but still good to install Windows XP, haha. Where did you get those Winbond W241024AK-15 chips from? …

I need to change my Debug Card before proceeding! I disagree. I would first make a sure that I have a working pair of FPM SIMMs. Is RAM error, won't it give some BEEP CODE?! Can you suggest any eBay listing? As far as I know the mainboard needs at least the first 64 kiloByte to do something. So …

@Thermalwrong and @TheMobRules I was not aware of difference between EDO vs FPM RAMs, but these RAMs (which I refer as EDO RAMs) are actually used with this motherboard/system. See the Green pair, it came with the complete PC set. The Yellow pair was bought as upgrade. These are not eBay products. …
