It is working well and I thank you for your help, as well as everyone else who responded. Your advice, suggestions, and inspiration led to my success.

I am very impressed by how thorough, at least in appearance, the Borland EMS test is. The only test the failed was the last test, something about Function 19, Non-volatile handles not supported.

I went in and ran Manifest to show me the memory map with nothing loaded; no autoexec and no config. I found some available memory at C800 so I adjusted the device line to: DEVICE=C:\DOS\XMA2EMS.SYS FRAME=C800 (and behold it worked, it was the only frame the system showed available along with...

Both lines tested in config.sys separately, the adapter would test up to 1024K and then fail...

Adding FRAME=E000 causes the driver to fail load. The complete line is device=c:\dos\xma2ems.sys frame=e000 p0=c800 p1=cc00 p3=d400 p254=d800 p255=dc00

Here is what the ROM Dumper was able to pull; using the -full switch: 1. C000C5FF.ROM = PhoenixVIEW VGA Compatible BIOS (VGA Card) 2. F000F7FF.ROM = 62X0280COPR IBM CORP., 1981, 1985 (assume IBM BIOS?) 3. F800FFFF.ROM = 62X0280COPR IBM CORP,, 1981, 1985 (assume also BIOS?)

There's nothing in the ROM socket of the card, unless the card has its' own separate ROM on there someplace.

I found one of those cards, without the SIMMs, for what I call "stupid money".

Each AST expansion only adds 1.5 megs of extended RAM. Since the IBM card is a true IBM expanded memory card, I thought why not add that. Using QRAM's Manifest, here is what I found, assuming accuracy:

I have installed in this PC/AT, a Phoenix VGA card, Intel 8/16 LAN card, 2 AST memory expansion cards, and this expanded memory card. I'm not sure I can move it or how I would.

Yes I did but I went back this afternoon with a clear head and tried those config.sys lines again and did make some progress with this line... "device=c:\dos\xma2ems.sys p0=d000 p1=d400 p2=d800 p3=dc00" ...and this is the new result, so there is movement, but as you see in the screenshot, it...

Did you ever have any problem with the driver? I'm having this issue... https://forum.vcfed.org/index.php?threads/ibm-expanded-memory-card-driver.1239774/#post-1273124

I tried that as the only line in config.sys; I even tried just "device=c:\dos\xma2ems.sys (which was supposed to poll the system and it would tell you which frames were available and I would get this: Boot up Advanced Diagnostics 2.07 for PC AT and here would be the results; passed... so I am...

Chuck, thank you. I have some useful/less trivia for you. I was able to snag some IBM DOS 4 & 5 from Texas. DOS 4 appears to be IBM for IBM release where the DOS 5 appeared to be IBM for other OEM releases. The documentation in both versions mentions XMA2EMS.SYS and XMAEM.ASYS. DOS 4 disks...

I will attempt to scan and get it to you, please PM me if there is an e-mail address or other method I can use.

Did anyone get a digital copy of these; images, et. al?

Because the box it came in and manual that came with it say so. The manual only provides information on how to install it into a 5160, 5170, 8530, and 3270 PC and setting backfill for base memory in each system. There was an updated version of standard IBM diagnostics but no driver disk also...

I picked up the IBM 2 meg expanded memory card; has a parallel port with it, but no driver came with the box or documentation, and I'm wondering did the card come without a driver, and if it didn't, what software might have used the card natively, and if it did have a driver or a compatible 3rd...

I'll have to forgo it for the time being and use the XENIX 2.0 images and see if I get different results.
