QEMM-386
If you are using QEMM version 5.0 or higher, there is a file called MCA.ADL
that QEMM uses to identify option ROMs in the system. To make QEMM
aware of the MCMaster's Option ROM, you should edit MCA.ADL to contain
the following lines.
These entries need to be in order by board ID (the four-digit hex number before
the product's name at the top of each
entry), so be sure and insert these lines at
the appropriate places in the ADL file.
008E Kingston MCMaster 486
X X X XX10XXXX /AROM=D000-D3FF

X X X XX11XXXX /AROM=D800-DBFF
/xst=D800
X X X XX01XXXX /AROM=C800-CBFF
/xst=C800
Note: Only include the text in italics (/xst=...) if you are installing QEMM
6.0 or higher. The /xst switch is to support QEMM 6.0's Stealth
Mode, as explained in the next section.
Some releases of QEMM might already include references to the MCMaster in
the MCA.ADL file.
QEMM 6.0 Stealth Mode
QEMM version 6.0 has a "stealth" mode, in which it attempts to free up more
upper memory blocks by hiding the ROM BIOS and option ROMs. Consult
Quarterdeck's documentation for a detailed explanation of stealth mode.
Unfortunately, the MCMaster's option ROM can't be "hidden" in this way
without causing problems for the MCMaster.
Quarterdeck has provided a way to exclude an Option ROM from being
"stealthed." Edit the MCA.ADL file as shown on the previous page, and
include the /xst=... switches as shown. When QEMM386 starts up, it reads this
file and uses it to locate the MCMaster's option ROM.
