- Excellent answer Doc, but just in case Art didn't completely catch
- what you meant, I'll clarify.
- QRAM allows you to load device drivers, TSRs, buffers, etc into high RAM
- rather than conventional memory ( the dreaded 640K limit) allowing bigger
- programs to run, larger files to be edited/manipulated, etc.
- QEXT.SYS, in managing extended memory, allows those DOS programs requiring
- more than 1mb RAM like 123 Release 3.1 to run when combined with those 286s
- with more than 1 mb RAM.
