One particular point, if you require EMS and UMB, then move the EMS page frame down to the top of the video ROM to avoid splitting the UMB space. AT2 states 8MB+ of EXTENDED memory, seems it uses DPMI with GO32 - I thought DPMI didn't need EMM386, but EMM386 is compatible with DPMI. It's possible …

If the 1000uF 10V are for CPU Vcore, then you could drop them to 6.3V models, I just can't think of anything inbetween 5V and 12V that would be on a motherboard. CPU Vcore would need to be low ESR, so maybe in the original, 10V caps had better ESR?

Those 1000uF 10v are astonishingly expensive... are the 16V ones any larger, if not you could substitute those. Oops, misread, those are 100 not 1000 Also, trying to figure out what would need 10V caps on a motherboard The ATX PSU delivers 12V (16V caps), 5V (6.3V caps, 10V could be there), 3.3V ( …

If the EMS requirement can be satisfied by 4.0 spec (not compliant with 3.2), then you could try P0=B000 P1=B400 P2=D800 P3=DC00 Before that, try the HIGHSCAN parameter to see if it can allocate into the E000 block - it only needs to find one more page ... E000-E3FF and it could allocate a D400 page …

I'd be tempted to add a UDMA driver to the set, either Triones or XHDD / XDVD2 for optical, as you can get improved DOS disk performance. Might also be worth looking at non-EMM386 UMB like UMBPCI if you need to max conventional memory while remaining in real mode. FASTVID may also be worth a go
