"expanded" memory w/ xenix 2.1.3

[RICHARD RONTELTAP]

If you have 1MB RAM in your pc/it, it will be 512K base, and 512K
extended memory. (I think this is the RAM you miss).
 
You have to tell the Intel board that there is already 512K RAM of
extended memory in the system. (You can do this with DIP switches) 
That's all!
 
Don't forget to set the extended RAM to 2560K (2.5 MB) with your
diagnostics program.
