[comp.sys.ibm.pc] switching turbo speeds

tim@cit-vax.UUCP (09/20/87)

I know that this was just discussed.  It is amazing how you could care
less about a subject one week, and the next ....

Please respond to me by mail so as not to bore the net.

How does one change the speed of an AT via software.  I have a switch on
the front to do it, and C-A-minus also does it.  What port is it poking?

Thanks in advance,

Tim
