[comp.sys.ibm.pc] AT Turbo Clone

schriste@uceng.UC.EDU (steven v christensen) (06/10/89)

I have an AT Compatible (called VIP-200) which uses Phoenix Bios 3.10.00.
It has a Turbo switch on the front panel, which can switch the computer
from 6Mhz to 13Mhz. The same can also be done with a key combination
"CTL-ALT-\". This acts as a toggle switch.

I would like to find the way they (Phoenix) do that via software, since
I would like to control the Turbo mode in a program. I believe it is
probably one or more OUT calls. Can anyone tell me how this is done?

I had asked this through INFO-IBMPC, and a couple of people sent me replies,
but the majority talked about _XT_ clone turbo. The XT clones do things
different from AT clones.

Thanks,
