4-76 ROM-DOS Internal Commands
V E R S I O N . S Y S
CONFIG.SYS Command
VERSION.SYS modifies the version number that ROM-DOS reports. This
device performs the same function as the Internal VER command. The
difference is that VERSION.SYS allows the change to occur during
CONFIG.SYS processing so that version-specific device drivers can load
properly.
Syntax
DEVICE=VERSION.SYS n.nn
Remarks
Specify the new version number, n.nn, with two digits after the decimal.
Note that this command revises only the DOS version number record; it
does not change the actual operating system loaded in the computer.
The version number change can be verified after booting using the VER
command.
Example
DEVICE=VERSION.SYS 5.0
Changes the record of current DOS version in use to DOS 5.0. Any
programs that are executed, following this command, recognize that DOS
5.0 is running.
