[comp.sys.ibm.pc] Reset Switch on IBM PC/XT

sandy@uhmanoa.UUCP (04/18/87)

	I have an IBM PC/XT Portable (one of the old ones) Running
PC-DOS 3.1, 640K, Color/graphics...
	Also have a 32M Seagate 238 Drive, OMTI Controller. 
	Anyway. some time back a reset switch was posted to the net which
involved putting amomentary switch across pins 11 and 13 of the 
8284A Clock Chip. Pressing the switch resets the system.  The 
posting also included a small DEBUG session to create a program
set1234 to change the value of offset 1234 to stop the RAM test when
the reset switch is pressed.
	Anyway the switch resets the system fine in most cases.  
However when I run the PARKAL command I have to park the command
and then press the reset, without returning to dos or turning the
system off, I get POST error
	1701
	ERROR.(RESUME="F1" KEY)

	And pressing F1 just clear the screen and hangs the system.

	If After running PARKAL I press Ctl-Alt-Del everything works
fine.

	Now questions:
		1) What does the error mean?
		2) Is this a problem I should be concerned with or is it
			something to do with the fact that my drive is an RLL
			drive and the POST has problems?
		3) If true to second part of 2) then why does ctl-Alt-Del
			work fine?  I thought the RESET Switch with se1234 was
			supposed to simulate ctl-Alt-Del.

	Please reply to me directly or to net if you think it is of
general interest.

	Thanks......
