ID:EX Microsoft EXCEL 2.1 in DESQview
Quarterdeck Technical Note
by Stan Young
QEMM-386 is compatible with EXCEL 2.1. However, if QEMM is loaded
in your CONFIG.SYS file, EXCEL will always report that the QEMM
driver and itself are incompatible. This is because the EXCEL
installation program, which seems to use code from the Microsoft
Windows/386 installation, scans the CONFIG.SYS file, finds QEMM,
and assumes incompatibility. It makes no test of the driver.
You can install EXCEL in the following way:
Rename the QEMM.SYS file on your hard drive to QEMX.SYS and
modify your CONFIG.SYS file to specify:
DEVICE=QEMX.SYS EXT=64
(QEMM 5.10 and later installs a driver called QEMM386.SYS, not
QEMM.SYS. If EXCEL 2.1 has the same negative reaction to
QEMM386.SYS that it does to QEMM.SYS, the rename to QEMX.SYS
should work for the recent QEMM's as well as the earlier ones.)
QEMM will boot up fine under the new name. Then simply install
EXCEL. EXCEL will place a driver called HIMEM.SYS in your
CONFIG.SYS file. HIMEM.SYS should not be loaded with QEMM 5.00
and later, which performs the same functions as HIMEM; delete the
HIMEM line from your CONFIG.SYS in this case. QEMM 4.23 can
coexist with HIMEM.SYS; it may be necessary to put the EXTMEM=64
parameter on the QEMM line in CONFIG.SYS, and possibly to play
with the order of the HIMEM.SYS and QEMM.SYS drivers.
After you rename the QEMM.SYS driver, EXCEL will not complain
about its presence in the CONFIG.SYS. EXCEL will be able to
function and will use the expanded memory provided by the driver.
Once EXCEL is installed, you can rename the QEMX.SYS driver back
to QEMM.SYS and change the CONFIG.SYS file to reflect the
original name if you desire, as EXCEL makes no further tests of
the system and will be able to use the memory regardless of the
name of the driver. However, you might want to skip this step:
the driver will work fine under any name, and renaming the file
to QEMM.SYS will cause the same problem if you have occasion to
run the EXCEL install program again.
