I am currently using a program from QuarterDeck called "QRAM 2.0" which has the ability to extend conventional memory beyond 640k (if UMB is contiguous), and load drivers into UMBs. I have so far managed to free up 144kb in UMBs and have successfully loaded all of my drivers into it. However, it would be really nice if I could load DOS into UMB as well. The DOS= line does not work on an XT as far as I know, because it requires HIMEM.SYS to be loaded first. That is normally how one loads DOS HIGH. Despite what logic says, DOS=UMB does not load DOS into UMB, it just allows DOS to manage UMBs, which won't work on an XT.
I suspect that loading DOS UMB would require some kind of proprietary software. It's very possible that QRAM has the functionality built in, but I don't have the proper documentation, and the read.me file does not cover all the specifics of the software. Does anyone in here have experience with QRAM, or any other software that can stuff DOS into the UMB on an XT?
