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

XX X XX10XXXX /AROM=D000-D3FF /xst=D000X X X XX11XXXX /AROM=D800-DBFF /xst=D800X X X XX01XXXX /AROM=C800-CBFF /xst=C800

Note: Only include the text in italics (/xst=...) if you are installing QEMM

6.0or 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.
