Elsa supported Multi Graphics (up to four Winner 2000 Pro/X) with one large Desktop in its Win 3.x Driver and above. So yes, Win95 can be used with Multi Graphic Cards / Displays. But don’t know whether its possible with Onboard CL 5429 + Elsa S3

In this case you should make sure, that both graphic cards use different ressources (IRQ/adress). So you should chose a graphics card, where you can switch/disable the ressources.

For DOS / VESA graphic modes (Doom, Quake, PCPBench, etc.) i got the same framerates with 486 Dx2 66 with following ISA cards: S3 801 ATI Mach32 ET4000AX I would assume, that the S3 928 ISA and ATI Mach64 ISA would perform equal in DOS to the cards above. Also some Cirrus Logic cards should be on …

Sounds that V-sync is active. Look for an option in the driver to disable it. And it seems that both chips are working correct.

Dual CPU gives me the feeling and the experience of double horsepower in Multitasking Apps. And it fits much more the desire for a special retro built. Some, maybe the half, of the Q3 engine games support the SMP feature (without crashes) like Q3A. Which results in appr. 20% higher frame rates over …

You can use your Am5x86 as a DX4 100 with 3x 33MHz to „emulate“ the AMD DX4 100, so you can keep it installed and switch between the classes. The AMD DX4 100 arrived the marked in the end of 1994 the intel DX4 100 in Q1/94. The intel has some improvements over the AMD, one is the better …

If you use more than one VLB card with 40MHz the transparent mode gets buggy. Also switching JP26 (D-ND) can help. And i found out long term stability issues (sporadic crashes) with the 10ns ISSI 128k8 chips (several batches from several vendors) at clocks over 33MHz. The latencys didn’t matter, …

Yes, POD5V83 ran wonderfully on those late PCI486 boards with WB support. But the reality is almost anyone who owned such a board probably had at least a DX4 or probably a 5x86 already. So in my opinion it's not a realistic upgrade scenario. Maybe we misunderstood, the intel Plato is the Premiere …

Did you try the MMX Overdrive on the Plato or do you know whether it is running on the Plato? Physical it should but the BIOS needs the sufficient microcode patch.

Very nice job, impressive. For best performance with your SV2GX4 you should activate the dirty bit in your BIOS in L2WB. Therefore you have to modify some registers and update your BIOS. The official BIOS doesn’t support dirty bit. The Am5x86 runs well with L1WB together with the AHA2840 (2842 is …

I think you can find an overclock option for the ATI card within the regular driver (Catalyst Controll Center). The GPU itself is maybe easy to overclock, but the RAM could be selected for the lower clocks and so more difficult to overclock. Maybe you can obtain the AIW with 128MB and w/o FireWire, …
