OMG........
It works. Mikey99, you were right all along. I finally got an image of MS-DOS 3.10 ready to go and booted the machine. It didn't work any other drivers except those early v1.0 circa 1985 drivers you sent me in DOS 3.10. I didn't try the other newer drivers in DOS 3.10, because what's the point? They don't work for newer DOS versions so why bother.
WHY WHY WHY? Why would they only make the card compatible with one set of drivers that only work on DOS 3.0 or 3.10? Now we're limited to those versions if we want to use our Above Boards?
What I finally did just to test and see if it worked, was booted from a DOS 3.10 diskette, and inserted the earlier driver disk. I ran the setupat.exe program, when it asked me which disk, I selected other. This time it didn't give me the error message that it couldn't find the card so it seemed promising. It finished and then quit the program. It edited the config.sys and autoexec.bat files on my c: drive. I copied those over to the A: DOS 3.10 boot diskette. There wasn't much room left so I only copied emm.sys to the A drive to boot and see if it worked.
I booted from the A drive and it loaded. EMM.sys tested the memory after dos booted. Apparently, MEM must not be a command for DOS 3.10 so I went on my C drive where my newer driver files for Above Boards were and ran chkmem.exe. Thats the pic below.
Now it seems to be working, but it sucks that only dos 3.10 is supported. I never got any messages about it not being supported in DOS 6.22 like mikey99 did, it just said card wasn't detected. WTF.
Anyone recommend a better supported memory board for AT's?
