= SUMMARY =

The following information is from the MACH 20 README.DOC file for version 1.0.

Setting Up SMARTDrive
The INSTALL program on the MACH 20 Memory Plus Installation disk can set up your system to use SMARTDrive. INSTALL automatically copies SMARTDRV.SYS from the MACH 20 Memory Plus Installation disk to the disk you use to start your computer. If you have the minimum of 256K of available expanded memory required to run SMARTDrive, and you choose to use SMARTDrive, INSTALL will also add a SMARTDrive command line to your CONFIG.SYS file. If you don’t have a CONFIG.SYS file, INSTALL creates one for you. The SMARTDrive command line has the following form:

DEVICE=[d:][path]SMARTDRV.SYS [size] /A

where [d:] and [path] are the disk drive and directory where the SMARTDRV.SYS file is stored. The /A switch specifies that you have expanded memory. [size] is the amount of expanded memory SMARTDrive will have. INSTALL determines how much memory to set aside for SMARTDrive based on the amount of available expanded memory and whether you plan to run other programs that use expanded memory. The program gives you two choices: either set aside all of the expanded memory for SMARTDrive, or set aside half (or 256K, whichever is greater) for SMARTDrive and leave the rest for other programs that use expanded memory. At least 256K of available expanded memory is required to run SMARTDrive (256K is the default size parameter). Once SMARTDrive is installed, the program is operational the next time you start your computer. From then on, SMARTDrive will start each time you start DOS.

Specifying the Memory Amount Allotted to SMARTDrive
If you want to specify a different amount of expanded memory for SMARTDrive, you can edit the SMARTDRV.SYS command line in your CONFIG.SYS file. However, if you plan to run an application that uses expanded memory, make sure you specify a size that leaves enough memory for that application. WARNING: If you specify more memory than you have available for SMARTDrive, you MAY DESTROY THE CONTENTS OF YOUR HARD DISK. To determine how much expanded memory you have available, add up the amount of standard memory in your system and the amount of memory on your MACH 20 Memory Plus board. Then subtract 640K (the amount of standard memory plus backfill from Memory Plus) from this total. If the result is less than 256K, you don’t have enough expanded memory to run SMARTDrive. If the result is at least 256K, you can select any amount of memory between 256K and the total to give to SMARTDrive. SMARTDrive will round up the amount to the next highest value that is divisible by 16.
