Re: Pentium MMX Retro-PC

So, time for another update! Today I took my 32 GB CF card that I tested yesterday and took the plunge to install Windows 95 with USB support on it. Now my particular version of Windows 95 does not boot from CDROM, and given I have no empty floppies and no way to burn a CD, I had to get a little …

Re: Pentium MMX Retro-PC

Well, I found some demos and used the Glide2x.ovl from the original driver. I'm happy to report the Voodoo2 still works, after being thrown around for almost 20 years in bins, boxes and generally not being taken care of (I now realize what a sin this was! :lol:) Amazing, hats off to Creative (It's a …

Re: Pentium MMX Retro-PC

You do realize that cache hit rates for most software are typically at least in the 90% region. That means that 90% of the time the CPU wants to read or write memory, it will find the memory it wants to access in it's cache or the L2 cache. The The video you linked from LGR showed that adding the …

Re: Pentium MMX Retro-PC

That all being said, let's get back on topic. The PC is now in it's final position just left of the other PCs: IMG_20180816_082620.jpg So what I managed to do in the meanwhile: - Got a new-ish Microsoft PS/2 mouse, which solves all the problems the old COM-port mouse had with it freezing in Windows …

Re: Pentium MMX Retro-PC

Dude, read some info on how L2 cache works, really! You are completely misinformed. The size of the code is irrelevant, as it's about RAM blocks that are accessed often (either code or data, doesn't matter). That's also where the 64 MB limit is coming from. There's a TAG RAM chip which can hold …

Re: Pentium MMX Retro-PC

No, that's not how cache works. Whenever data is loaded from RAM, it will end up in the cache. Next time that data is needed, the CPU can access it much faster. Or simply put: memory throughput is much higher when cached. The size of a program has nothing to do with that. The problem with more RAM …

Re: Pentium MMX Retro-PC

No, what we mean is that the L2 cache does not work at all with memory addresses above 64meg on the 430TX chipset. Yep, I got that. Which is why I explained what I did. Still, I don't think it will matter much. Sure, it will matter if large parts of the program can be cached into the cache - which …

Re: Pentium MMX Retro-PC

That board has the Intel 430TX chipset. You do know it can only cache up to 64mb ram? As others have mentioned, 430TX can cache a max of 64MB. Use any more and it will probably slow down your system provided your system doesn't require an extensive amount of memory. 64MB should be fine :) No I did …

Re: Pentium MMX Retro-PC

Well, you're not going to get far with MIDI in DOS with that CT4170 unless you have an external module as it has no onboard synthesizer. I would get a real/better ISA card for that. Also I'd be on the lookout for a replacement for that Rage card for something that's a bit more DOS compatible …

Pentium MMX Retro-PC

Hello fellow vogoners! I have been reading this awesome forum for quite some time now; and inspired by all this talk and the great retro content on YouTube from the likes of LGR, Nostalgia Nerd, Metal Jesus Rocks, 8-bit guy, .... I decided to get a retro PC build of my own going. I had been …
