When overclocking anything, it's the luck of the draw. Not every seemingly identical kit will clock the same. You're unlucky that your kit doesn't overclock, another of the same model and specs might overclock amazingly.

The large online retailer I normally buy new stuff from has hardly any new cases with external drive bays. 3.5" is impossible to find, as are budget cases with external 5.25". Cheapest with 5.25 is approaching £100! Time to explore a few other sites. I have lots of old cases, but will be wanting a …

Went to the local second-hand store and to my surprise they have a bunch of old hardware around for next to nothing. So I'm back with: - A Matrox Millenium G400 16MB - Intel 486 SX-25 - Intel 486 DX-33 - Intel 486 DX4-100 supporting write-back - 2x Intel Pentium 166 with different markings - AMD K6 …

Welcome! Some members even consider early Core CPUs/systems to be retro, so most of your kit would qualify. I'm one of those members. The first C2Ds released in 2006, that's 17 years. 3-4 years from now there will be a generation of legal adults who haven't been alive when the latest C2Q CPU …

I wrote some code to detect CPUs and FPUs some years ago, with the non-CPUID stuff based on Intel examples: https://sourceforge.net/p/cpuinfo/code/ci/default/tree/CPUInfo.c It can at the very least detect the family of CPUs and FPUs that do not have CPUID, so it will know if it's a 8086, 286, 386 …

Thanks. Can you please send me the modified code, so I can add it to my code? It all looks how I intended it to. Not sure when/if I'll add clock speed detection.

Does the original Memtest (not Memtest86) work on older systems?

Thanks. I never tried writing code to detect what fpu was present. It was never written as release code, I merely offered the CPU detection code for anyone who wants it. I'll have to see at some point how to detect what fpu is present, not sure how to go about that. Will have to do some research on …

Does it not find the ID any other way? Such as from the BIOS? It's difficult on some systems, but I didn't have enough boards when I wrote it to test as thoroughly as I hope to when I finish organising things in my new home 😀

Ray, I just sent you my CPUID code (it stops shortly after x64 cpus came out, has a lot of old data). It's public domain with a copyright, so can be freely shared and used as long as I am given credit for code I supply. I also have data relating to various 808x versions that is not yet in the files, …

Sorry to be that person, but the best way to end the angry comments is for both of you to just ignore each other. I see a useful thread at risk of getting moderated if everyone can't just be nice to each other (or quiet, that would work as well). I don't know what happened in PMs, but somewhere down …

If you don't want to use a throttling utility, I'd stick with the 1.1 GHz Athlon. The XP will be far too fast for some DOS games, and the 1.1 GHz is period correct for 98 (there were two socket A 1.1 GHz, both released in 2000)

I thought it was easiest if you install DOS first, then XP. Haven't set up a dual boot in almost 20 years though (I'll be doing more retro stuff to test everything in my collection once I get my new house organised, so I have room to work on stuff without storing half of it in a damp garage)
