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. Any more questions I can answer directly with e-mail. Lawrence Dee
