I have a XT clone that can be switch to 8mhz (Turbo) from the keyboard, 
however, after a software initialize to the text mode, I am drop back to
the 4.77mhs mode, the keyboard switch consists of pressing 
Ctrl alt -  (Control, alternate, minus) at the same time, can any one tell
me
	1) how to "lock" to the 8mhz mode?
	2) how to write a program (in asm or TP4 or in C) to do the switching?
	   rather than pressing the 3 keys?  (and the turbo mode can be entered
	   from turn on the computer?)
