MS-DOS Internal Commands
The DOS Command
Description:
Specifies that MS-DOS should maintain a link to the upper memory area, load part of itself into the high memory area (HMA), or both.
Command Syntax:
DOS=HIGH|LOW[,UMB|,NOUMB]
DOS=[HIGH,|LOW,]UMB|NOUMB
Explanation of Syntax:
[UMB|NOUMB]specifies whether MS-DOS should manage upper memory blocks
(UMBs)created by a UMB provider such as EMM386.EXE. The UMB parameter
specifies that MS-DOS should manage UMBs, if they exist. The NOUMB
parameter specifies that MS-DOS should not manage UMBs. The default
setting is NOUMB.
[HIGH|LOW]specifies whether MS-DOS should attempt to load a part of
itself into the HMA (HIGH) or keep all of MS-DOS in conventional memory
(LOW). The default setting is LOW.
Command Use:
This command can only be used in the config.sys file.
