[comp.sys.ibm.pc.hardware] Software switching of TURBO on AT clone motherboard

iiitsh@cybaswan.UUCP (Steve Hosgood) (07/12/90)

The manual for the ZEN 160B AT clone motherboard states that the TURBO
clock mode (i.e 12MHz instead of the usual 8MHz) can be switched on/off
by typing CTL-ALT-<minus>. (This is with AWARD 3.3 BIOS by the way.. )

I need to be able to switch clock speeds from inside a program. Can anyone
tell me how to do this please?

E-mail will be summarised to the net where appropriate.
Thanks in advance
