SUMMARY
The following are suggested settings for the SMARTDrive and RAMDrive device drivers with Windows version 3.0 standard and enhanced modes. These settings are based on the total system memory in the machine. Note that in the table, &quot;SMARTDrive Size&quot; refers to the minimum cache size. You specify this size as the second parameter to the SMARTDrive command line in the CONFIG.SYS file. The second parameter is available starting with SMARTDrive version 3.03. For example:

Device=C:\DOS\SMARTDRV.SYS 2048 1024

Page 536 of the &quot;Microsoft Windows User's Guide&quot; suggests installing a 256K RAMDrive and then setting the TEMP environment variable to the RAMDrive drive letter. This is possible to accomplish but NOT recommended by Microsoft.

Using a small RAMDrive for the TEMP variable and printing large jobs will cause problems. The minimum RAMDrive setting depends on the total memory installed in your system. The RAMDrive is installed in the CONFIG.SYS file. For example:

DEVICE=C:\DOS\RAMDRIVE.SYS /E 2048



Standard Mode
If standard mode is your normal operating environment, the following is true:   Megabytes       SMARTDrive      RAMDrive        Set TEMP to                   Size            Size            RAMDrive? -      --              ---
