Turbo Hot Key Combination May Fail with KEYB.COM PSS ID Number: Q64076 Article last modified on 02-16-1993 PSS database name: O_MSDOS

3.x 4.00 4.01

MS-DOS

Summary:

It has been reported that if the KEYB.COM command is issued, the hot key sequence to change a machine’s CPU speed may not work.

A customer reported this problem with an XT compatible machine, using a CTRL+ALT+BACKSPACE hot key combination to toggle the CPU speed.

More Information:

Some OEM installation programs automatically place the KEYB.COM command in the AUTOEXEC.BAT file with the U.S. keyboard parameters. If KEYB.COM is in your AUTOEXEC.BAT file, you can remove it, because the U.S. keyboard is the default.
