Well, and I have 20 MB (out of 32) in my 386sx.
4 MB are allocated for EMS. Topcat chipset.

It even runs Windows 95B.
SB 16 ASP plays ADPCM compressed Windows sounds.
ET4000/W32 ISA allows full window moving.
1542B does busmaster SCSI transfers.
I yet need to find a good network card.

Yes, it is still a 386sx. Any tasks that require CPU power are terribly slow.

Sorry for going off on a tangent here. Do you have a photo of that ET4000/W32 ISA card ? Is it already listed on TRW ?
The only ISA w32 is see there doesn't have a bios listed. C/Would you supply it?

I just opened a thread on TRW discord with photos and a BIOS image on behalf of Disruptor. I've attached the photos here as well, expecting the forum software would reduce the image quality, but it seems the allowed file size has been increased, so you can enjoy the images here in full quality as well.

FCC ID: KAZET4W32TCISA is a graphics card with Tseng Labs ET4000/W32 chip for personal computers with ISA bus.

Oh, that FCC ID is funny. KAZ is the vendor code of "Trident Computer Inc" in Taiwan. This sounds very similar to, but quite likely is entirely different from "Trident Microsystems", an American company known for its TVGA line of graphics chip, most of them having mediocre performance.

All worked allthough having 16mb installed. Maybe that was a mistake.

Please test with 8 or 12 MB of RAM.
Note: A 386sx just needs pairs of RAM. If you have 4 banks for 8 modules, try first 2 banks with 1 MB modules and 3rd bank with 4 MB modules. If you have 2 banks for 4 modules, try 4 MB modules in 1st bank and leave 2nd bank blank (or try whether 1 MB modules are recognized for 10 MB).
Thanks in advance.

I re-run the benchmarks while only having 8MB installed:

PCPBench: same results
DNRATE VGA: 11
DNRATE VESAVGA: 13

Conclusion:
1. There is a performance increase due to LFB VGA in some scenarios (Duke=yes, PCPB=no)
2. There is no difference in overall-performance nor performance-differences between 8MB vs 16MB RAM while using LFB. Is this strange as LFB might be located at 15MB? I dont know 😒
