Is there a good DOS benchmark for testing "2D" features that were common in games? Stuff like hardware scrolling, writing to video memory, filling (2D) polygons, page flipping, changing palettes, etc. Well, DOS games usually don't use any acceleration features since those are different between …

Doesn't the P2B have jumpers to change the FSB? At least that's what Google tells me. Of course that may depend on the revision... In that case you could change the FSB from 100MHz to 66MHz.

It is possible that the Geforce256 uses to much current for a socket 7 motherboard. A GF2MX is much more power efficient and not necessarily slower, especially not in a socket 7 system. Phil wrote that it runs fine in your board, though: What is the best graphics card for Super Socket 7? My journey …

I can't see how you either disabled all RAM above 640k or only installed 640k in the 586 so there was no conflict with existing memory. That's a good point. All I did was to not enable shadow memory.. The remaining memory was treated as extended memory which begins beyond 1MiB. Memory between 640k …

I'd say a TNT2 (or G450) might be bottlenecked by a K6-2 depending on the resolution. At 640x480 it will certainly be bottlenecked, at 1024x768 or higher probably not. A Radeon 7000 is slow for the time it came out, but it should still be faster than any TNT2, Rage 128 or G4xx. Not hardware TnL, …

My guess is that the DMA capabilities don't depend on the card but on the mainboard chipset. Several chipsets are able to map RAM into the upper memory area to be used for UMBs, they often don't support DMA for this memory. The card definitely has to be in half-mode, I don't know what the default is …

Win 95/98 was always better and had pretty much no issues with "win 3.1 era" games. People who still used Win 3.1 over 95 probably had a 386/486 @ 25/33MHz instead of a DX2 or Pentium. Or just not enough RAM. 4MB is fine for Win 3.1, 8MB is generous. For 95 8MB is the official minimum and no fun to …

According to http://pclinks.xtreemhost.com/chipsets_pentium.htm the VT82C585VP (apparently the earlies Socket 7 chipset from VIA) supports at most RAM modules with 16MBit chips and should also support SDRAM (still possible that the BIOS or board don't support SDRAM).

Hard to say how the values compare, but if I take ADD as another example this looks good: ADD reg, reg: 2 (386) 1 (486) 1 (Cx486DLC) ADD mem, reg: 7 (386) 3 (486) 3 (Cx486DLC, 5 for cache miss) I'd say the 486 values don't allow for cache misses. The ranges for IMUL in 386 and 486 mean the execution …

I don't think you need a faster CPU with that video card. In glQuake it would probably max out with a PMMX 200 at 640x480, probably similar with Quake II. With a K6-2 good choices would obviously be Voodoo2 (SLI) or Voodoo 3 (expensive in PCI). (A single Voodoo2 will probably bottleneck the CPU …
