Btw, testing with a Klamath would be one of the things I would try as these are almost surely supported. ^this When you look at the timeline for this particular motherboard it is imo not at all clear that it should work with any other PII cpu than the Klamath on which the design (+ BIOS) was based. …

... But it only supports CPU up to 333 Mhz. Time for a BIOS update! That may be so but if you want to update the BIOS it seems(?) possible that you can only do that via software with a cpu installed that is actually recognized by the BIOS. In other words, you may need a may 1997 release, 2.8 volt, …

I chose 80 because it looks clean. 99 just would not look right no matter what. I had it at 66 before but got tired of it. I think the display is a quintessential part of the 486 vibe, which is why I love it. One option is to find a 2.5 digit display, if your front is exactly the same as the one I …

@evasive One question, maybe a silly one but I'm trying to improve my understanding here. His BIOS chip has a sticker that says [02/25/99] which is 8 months before the Coppermine was launched. If he needs to upgrade his BIOS for Coppermine support (if that is at all possible) should he not begin …

I just looked on eBay, there are a few for sale, but the prices are not very appealing, especially for a CPU with an easily cracked core. They are in general prohibitively expensive and maybe only worth it if you are seriously after the fastest s370 coppermine for an in-spec 440bx system. Anyway, …

The bridged ones could be for 2pin LED input signal from motherboard and the turbo LED on the case? (another 2 pin). I have a display with a similar set of 4 connectors (see photo) and in combination with a later 486 mobo only the 3-pin turbo switch connector (red-black-white) and the 2-pin 5volt …

Not meaning to start a debate, just for general info. The standard Intel SECC (PII and PIII) cassettes measure 14 millimetres width at the sides. The Foxconn measures 16 millimetres. I do not rule out that there may be common retention clips out there that can accomodate the Foxconn sink without …

interesting, do you have a more detailed picture of that? to me the heatsink looks like it's exactly the same width as a PII package with the nubs on the side: The nubs on the side are not the problem, nor is the width. These (server) heatsinks have a projection that is bent towards the back on …
