Note: Environment variables are set in CONFIG.SYS only at the end of CONFIG.SYS, regardless of where the SET command occurs. Consequently, these settings cannot be used by device drivers, and this command is generally only used if environment variables are required by TSRs loaded via the INSTALL= command, or if the application is being used as a command shell (e.g., turn-key application).

    RAM disks allow the PDT 3400’s RAM to be organized as a simulated disk to allow writable data storage. To create one or more RAM disks, use the Symbol RAM disk driver RDISK34T.SYS which is included as part of the Symbol PDT 3400 SDK.

  • Page 94: Using Emsalloc.sys To Increase Size Of Ram Disk

    Total 4096 KB (4 MB) To allow more flexibility in allocating RAM memory, Symbol supplies an EMS Allocation utility, EMSALLOC.SYS. This utility allows you to allocate less memory to MS-DOS, leaving additional memory available for use as EMS memory. The RAM allocation for MS-DOS can be adjusted from the default 640 KB down to a minimum of 256 KB.

  • Page 95: Using Stacker To Extend Ram Disk Storage

    Note: The amount of EMS memory and RAM Disk allocated must be balanced by the amount of RAM required by MS-DOS, by applications, and by Symbol-supplied drivers. For information on loading the EMSALLOC.SYS driver, refer to the section EMSALLOC.SYS in Chapter 4.
