on your computer. However, to use LIM-EMS, the EMM386.EXE and HIMEM.SYS drivers must be assigned in your CONFIG.SYS file as described below.

LIM-EMS and Software

Expanded memory requires two things for use:

The application you use must conform to the LIM-EMS standard.

To determine if your software can take advantage of expanded memory, refer to your software documentation. The manual should tell you clearly if your package can use expanded memory and may even tell you which version(s) of LIM-EMS it supports.

Your CONFIG.SYS file must contain the HIMEM.SYS extended memory driver and the expanded memory driver EMM386.EXE. These programs control (drive) access to expanded memory.

The following is an example of a CONFIG.SYS file with the extended memory driver in the fourth line and the expanded memory driver in the fifth line:

buffers = 30

files=30

device=c:\dos\setver.exe

device=c:\dos\himem.sys

device=c:\dos\emm386.exe

dos=high

LIM-EMS and Optional Additional Memory

T2150CD series computers come with 4096KB or 8192KB of RAM memory. If you plan to use large spreadsheets or process complicated graphics, you may want to expand the computer’s memory capacity by installing optional memory cards. Refer to Chapter 12, Optional Devices for more information about these cards.

RAMDRIVE

You can further enhance the performance of your computer by creating an MS-DOS RAMDRIVE, which simulates a physical disk using RAM. With no moving parts, a RAMDRIVE is much faster than a diskette or hard disk and it saves battery power. Loading programs or frequently accessed data files into a RAMDRIVE speeds up your software.

The MS-DOS RAMDRIVE feature lets you create a RAM disk from 4KB up to the total amount of available memory. RAMDRIVEs are supported by the AutoResume feature.
