That's it! Great job @unspec. I wonder what particular computer was compatible with it. It seems like it's a very niche thing.
Re: Soyo SY-6BA+ Not recognizing all memory
Posted on 2025-05-27, 17:41
I remember mixing and matching DIMMs for a SY-6BA+III because it only supported certain combinations of modules simultaneously (and in a specific order too). I'd suggest getting other DIMMs and trying different slots and combinations.

Hey Jan! Thanks for that link, it's very enlightening. So 1DA1 should be the latest BIOS for v1.2 according to SOYO themselves. I tried it and after some basic testing I noticed some instabilities (Write fault error reading C) that I hadn't noticed with the original 1CA2 BIOS. Also, that BIOS …

SY-5EH revisions v1.2 vs v1.3

The SOYO SY-5EH5, also called SY-5EHM, has a lot of revisions. What are the actual hardware differences between v1.2 and v1.3? I couldn't find any, yet according to Jan Steunebrink they should use different BIOSes. http://www.steunebrink.info/k6plus.htm 5EHM v1.2 Original BIOS: 5EH V1.2- 1CA2 10/21/ …

Basically they use the CPU for certain operations, which slow everything down. There isn't much more information about how it really works. Also seems not everything is 100% implemented. That explains why Doom performs relatively worse than Quake, which I think uses the FPU more than the ALU. For …

The Presario was designed to be non-upgradable. A few things I never bothered looking at, is 1. Are the 16 bit isa lines still accessible off the chipset somewhere 2. Is the pci bus still there on a chip somewhere (signalling using bodge wires would likely be terrible) 3. Was the 80mb ram limit …

My guess is that they focused on performance for VESA modes, as they are faster and easier to work with. All other modes were merely emulated for backward compatibility. I see. It shows a lack of seriousness and commitment. But probably the budget was low. I can't understand how you can emulate …

Maxing out Win95 conventional memory
Posted on 2025-03-18, 07:07
The whole point of this is research is to free up as much conventional memory as possible on machines that are not compatible with other memory managers, such as UMBPCI, while remaining in real mode. I'm using HIMEMX since it appears to be 100% compatible with HIMEM.SYS (is it?) and it frees as much …
