Memory Device Drivers
If you do not specify any parameters, EMM.SYS uses the default values for each.
Numeric values (nnnn) should be specified in decimal unless specifically noted otherwise
in the following descriptions.
Memory sizes should be specified in kilobytes (1024 bytes) without the last three digits at
the end of the number; for example, 32,767 bytes would be specified as 32.
A one- or two-character abbreviation is available for all parameters as listed in
parentheses after the long form version. For example, the abbreviation for the include
parameter is L.
Caution: If you plan to reassign address space in memory using some of the
following parameters, it is wise to first back up your hard disk drive. You can
inadvertently assign system ROM and almost surely crash the system and possibly
lose hard disk data while EMM.SYS loads.
Alternates = nn (A=) selects the number of high speed alternate mapping contexts
available. The default is 04.
Badremapped (BR) specifies that bad blocks may have been remapped by the system
BIOS. This only occurs with a BIOS that supports this feature. Bad block remapping
occurs only if this parameter is selected.
BufferDMA = nn (B=) specifies the size of the directmemory-access (DMA) remapping
buffer. The default is 32, sufficient for most standard operations. You can set the size of
the DMA buffer to any value from 16 KB to 128 KB if devices with specific requirements
are present.
