                         MMIDD New Option
                Document rev 1.00, December 5, 1991
     A new option has been added to the installable device driver
MMIDD for the 16 bit MicroMASTER 386.  The version is 1.03 and it
is to be used with MicroMASTER code rev 1.21 or later (it checks). 
The new option is r where r stands for relocate.  This will
relocate the resident interrupts (int 15h, 13h, 75h, 4bh) from the
top of conventional memory (9f00h segment) to lower memory in the
device driver.  This eliminates problems with programs that don't
know how to deal with memory being used between end of low memory
and the extended bios data area (like Windows).  It also sets up to
look for emm386 (and possibly some other LIMulators) and envelops
it to work properly with the VDS calls (int 4b).

     Other options are:
     i to install a cache toggle (SysRq)
     s start MicroMASTER (only used with i to start and install
cache toggle)
     blank will start the MicroMASTER

     examples:
     device=c:\aox\mmidd.sys r i

     The above command will replace the resident interrupts with
ones located in the device driver and install a cache toggle.  The
board must have already been started (ie not started by the device
driver).

     device=c:\aox\mmidd.sys

     The above command will start the MicroMASTER and put the
resident interrupts in the device driver along with the emm386
watcher.  If the board was already started and error is displayed
and no interrupts are replaced.

     device=c:\aox\mmidd.sys i s

     The above command will start the MicroMASTER and put the
resident interrupts in the device driver along with the emm386
watcher and a cache toggle.  If the board was already started and
error is displayed and no interrupts are replaced.
