WordPerfect Does Not Communicate With XMS Dri |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: The customer's Epson Equity MS-DOS 4.01 Reference Manual states that HIMEM.SYS "...serves two purposes: It adds almost 64KB of memory to the 640KB that MS-DOS programs can use, and it provides a machine-independent standard for programs to follow in storing data in extended memory." If it really adds 64K to the base 640K, does WP utilize this memory? Or is this memory still considered to be extended memory, and thus WP does not utilize it? Solutions: The 64K is available as stated in the DOS manual. However, it is only available to those programs that communicate to a driver that follows Extended Memory Standard (XMS) version 2.0. WP does not communicate to the XMS drivers, since it does not use extended memory. WP only works with and communicates directly with expanded memory drivers. WP cannot communicate with a extended memory manager such as HIMEM.SYS. Thus, it is unaware of the changes made by the HIMEM.SYS driver. |
