I want to set clock multiplier in Athlon XP-M 2400+ in DOS. Have
eMachines M5312 laptop with an MS-DOS 7.1 bootable partition. Bios
defaults the CPU clock to full speed (1.8GHz) and the thing then gets
tooo hot. When booted in WIN XP partition, CPU is throttled by ACPI and
runs cool.
So with PowerBasic 3.5 for DOS, I want to issue commands to set CPU to
lower clock speed, perhaps around half the maximum. Would also be
nice to program core voltage lower commensurate with the lower clock
speed. I would appreciate info on memory or I/O locations of control
registers, bit pattern, sequence of instructions, etc. to change
these CPU parameters.
Thanks, Barry.
