I think quite a bit of knowledge is actually lost over time. Some people tend to spend a bit of time and effort trying to learn it over again and with the internet those people are just easier to find. The hardware is dead simple compared to current and some “restricted “ info is in the public …

The BIOS is detecting it as a 486DX2, but Windows is able to ID it as a AMD processor. I've ran a program called CPUCHK, that tells me it is an AMD 5x86 running at 100MHZ. My understanding is that one of the reasons that the AMD chips are so compatible is that they are good at lying to the BIOS. …

Out of curiosity, What does the bios recognize the AMD CPU as ? It may take a long time for him to get the chip. The 66mhz version of the system and 50mhz version both had the same bios so hopefully IBM at least had dx4-100 support and it should see that. IBM was known for dirty tricks so he should …

Back when most ppl had 640K and Windows was just edging into people's consciousness, it was kinda regarded as a klunky DOS task switcher, and a desirable feature of DOS apps those days was to be "windows aware" not sure if that defines much really, I guess that it was well behaved, maybe could use …

I’ve often wondered why 8087/80287 weren’t made to be interchangeable Then 8088 folks could “upgrade” to a slower more feature rich FPU and 286 folks could reuse their old reliable when upgrading Seems like a waste considering the 8087 had less overhead and functionally everything needed to support …

Not best but most of us enjoyed the quirks of a Soundblaster, In my case my first non-Tandy sound was out of a vibra 16. So while Duke may have been composed on high end hardware it was usually enjoyed in classic scratchy 8 bit samples on your 486DX2 PS Dukes soundtrack is available in CD quality …

If you plan on sticking with Intel get the DX4- 100 overdrive appropriate for your system It will easily run at 75mhz and you can easily swap the crystal for 100mhz operations at a later time should you choose to take it on

If you can find an interposer the P24t will be the fastest. There also should be ways to force other bus speeds no matter what if your willing to dig and mod. Cyrix and AMD 5x86’s with a voltage regulator will run 4x25=100mhz as well Your onboard video and cache situation will hold you back even …
