COMMAND: COLDSET.COM
FUNCTION: Will set a hardware reset button for cold boot upon
next press.
FORMAT: COLDSET <cr>
There are no special operators or parameters.
TYPE: DOS external command
REMARKS: This program will cause a press of a hardware reset
button to initiate a cold boot upon the next press.
During a hardware reset, the memory location
0000:0472 is compared to the value 1234h. If they
are equal, then a WARM start indicated, causing the
memory tests to be skipped. If there is any other
value there, then a COLD start will cause the Power
On Self Test (POST) to be run. This program simply
sets the flag to 0000h, which will cause the reset
compare to evaluate false, initiating a cold boot.
Any data currently in memory will be LOST as if the
power switch has just been toggled. This program
requires a machine with a hardware reset switch to be
of any real value.
