It details features of DOS 6.22, such as DOS shell; better MemMaker
; improved MEM command; new Del-Tree command; better use of extended memory; smarter SmartDrive; and Drive Space.
We have teased out the necessary conventional RAM on our workstations thus far by using the DOS program MEMMAKER
, but a commercial memory utilization program such as QEMM or 386Max may eventually become a necessity.
One of the outstanding features of MS-DOS 6.0 and 6.2, both of which are now available, is a utility program, MEMMAKER.EXE, that will analyze your configuration and make the appropriate changes for you.
After optimizing with MEMMAKER, I tried using two commercial memory management programs, QEMM386 (Quarterdeck Office Systems, Santa Monica, Calif.) and 386MAX (Qualitas, Inc., Bethesda, Md.), to increase the amount of conventional memory even further.
Like MEMMAKER, both QEMM386 and 386MAX have automatic setup programs that evaluate your configuration and determine the best way to place your DOS, device drivers, and TSRs in memory.
Although we will not discuss option 2, users should be aware that DOS 6.0 and 6.2 versions come with a memory management utility called MemMaker that can do some sophisticated memory management.
Many of our machines were using DOS 5.0, which does not come with the MemMaker utility, so we began by tinkering with our configuration files.
It was originally installed to take advantage of two utilities that Microsoft shipped for the first time in DOS 6.0 -- DoubleSpace, a disk compression utility, and MemMaker, a memory manager.
Running MemMaker, also with Express Setup, took only a few minutes.
The results of running CHKDSK after loading DOS 6.2, deleting the remains of DOS 6.0 with the DELOLDOS command, deleting the STEPUP files, and running MemMaker are presented in Figure 2.
