ROM-DOS 6.22 Command Descriptions 3-49

D O S

CONFIG.SYS

Purpose

ROM-DOS can be loaded in special memory called the High Memory
Area or HMA to free more of the conventional (lower 640K) DOS
memory for use by applications.

Syntax

DOS=HIGH

Remarks

DOS=HIGH frees up more of the standard DOS memory for use by
applications.

This command only works on 286, 386, and 486 CPU's with extended
memory and Datalight's HIMEM.SYS High Memory Manager, or
equivalent. It does not work on standard XT class PC's. Setting
DOS=HIGH is ignored when ROM-DOS is in ROM.

DOS=HIGH also works on Chips and Technology's PC/Chip, if it has
extended memory and Chips and Technology's HIDOS.SYS device
driver, or another memory driver is loaded.

See the HIMEM.SYS device driver description in this manual. See
also 386MAX by Qualitas for more information.

Examples

DEVICE=HIMEM.SYS

DOS=HIGH

Loads the High Memory Area device driver and then loads ROM-DOS
into the HMA for increased conventional memory. The high memory
area device driver must be loaded first, before DOS=HIGH.
