For what it's worth Gary, just tested it with my 8088 (for the first time!). Works fine.
Unfortunately I'm winding things down here for a 2 week vacation in Europe. Not back until mid-July. So I won't be able to help much, but I have been using this board in all kinds of situations in the past few weeks, never a problem, even a new V2 CPLD driven 80386 prototype at 10MHz on the bus. One thing though, this is a second batch of boards made by PCBCart. It's the same Gurber files so there should be no changes, but you never know. Dave Fry, you are the only one with the first batch board. Do you have our 8088. Also can some other users out there check their 8088 with this board.

Subject: [N8VEM-S100:7300] V3 IDE with MSDOS
Looking for troubleshooting ideas....
I've put together the V3 IDE board, and it works perfectly with CP/M and the Z80 board.
Both IDE slots work fine in CP/M and I'm using the same flash memory cards and SYBA adapters as I used with the V2 card.
Unfortunately I can't get it to boot MSDOS.
Using an 8088 CPU card.
The card won't access properly using QO33,80/QO32,2B/QO30,00 etc either under the 8088 but works perfectly using the Z80.
I've tried swapping cards, adding I/O wait states on both IDE and CPU cards, swapping GAL's, swapping IC's, stripping most other boards from the system etc.
Thanks in advance for any ideas.
- Gary
