Hi, the memory card does really provide XMS?
I have similar one but it serves as EMS and standard p-mode games like Doom cannot use EMS.
The memory bandwidth is limited by ISA bus...
Yes, the memory card has settings (dip switches) for various conditions of memory allocation. You can set all the onboard memory up as XMS, as I have done, or you can setup part of the memory as EMS with two address control ports. This particular card should support LIM 4.0 EMS, which I've been told that the cheaper ones do not.

I'm a bit nervous to leave the DMA speed at 6.7 MB/s, given that 8.0 MB/s didn't work at all.
Adaptec has a DMA test in ROM you can use to safely test the higher speeds without risking data corruption. Open DOS DEBUG and go:
replace c800 with the base address of your ROM if different
I will test this out shortly, since I currently have the system out for troubleshooting HWiNFO and CHKCPU, both of which incorrectly report the CPU. Only Check-It Pro and AGSI v1.23 are reporting the CPU speed correctly.

Good photo report.
The rig turned out great - packed and tight, including the semi-messy cables in the box - for extra retro flavor.
Looking at your screenshots - it occurred to me that i never ran SpeedSys and Doom with that 286 CPU upgrade here (i think). Going to check that soon.
Your PS/2 mouse insistence is admiring :)
The cables couldn't have been neater because the ACARD was VERY particular about not being the last device on the SCSI bus. I tried various cables, terminators, and prayers. Sometimes it seemed like it would work as the final device, but next boot it would not. Some photos may show the ACARD as the final device, but that wasn't the final configuration. I also really wanted the CF card slot bracket to be on the outside of the case, but the length of the ACARD PCB prevented this. I'd have had to dangle the ACARD floating somewhere between the expansion cards, or create an extra long adapter cable to facilitate this. I did not want to bother. I also wanted to keep one slot bay open for the possible expansion of a second Everex memory card.
Because of my KVM's on both test stations, I really want the PS/2. Shuffling around mice is not for me.
EDIT: Note that there are more photos of the build on page 7 of this thread. Looks like the photos got split between pages, causing the first set of photos to be missed, as determined by the views differential.
