The Solution

The solution is to edit your CONFIG.SYS after the installation is done. Make
the disk cache about half the size of the MCMaster memory.

Version 3.0 of SMARTDRV does not need to be as precisely "tuned" as it used
to need to be. Previously, you had to balance the size of the disk cache against
the memory needs of your Windows applications. (Microsoft's MEMSET did
this for you.) With Windows 3.0, in 386 Enhanced Mode, Windows and
SMARTDRV will share the memory dynamically, depending on current
conditions. If Windows needs to grab more memory for other uses, it will be
able to. To read more about this, consult your Windows 3.0 documentation.

For a MCMaster with 4 MBytes, the entry might read:

DEVICE = C:\WINDOWS\SMARTDRV.SYS 2048 512

The first parameter specifies a maximum cache size of 2 Megabytes; the second
specifies a minimum of 512K. This should work for most users.

OS/2 2.0 and higher

For OS/2 2.x to work correctly with the MCMaster, the MCMaster's memory
configuration must be set to "Unmapped." Since OS/2 2.0 is "aware" of the
MCMaster and will load itself into the MCMaster's 32-bit memory, this does
not cause the performance problems that it would with other operating systems.
For more information on MCMaster memory modes, read "Memory Options".
