PROGRAM: IPL.COM

GENERAL FUNCTION: Performs a warm-boot (same as CTRL-ALT-DEL).


IPL - Initial Program Load (RE-BOOT) from .BAT etc.
===================================================

This little utility program simply performs the exact same
function as pressing CTRL-ALT-DEL, but can be typed in on
the DOS command line or placed in a .BAT file to cause an
automatic reboot when desired.

Invocation: A:>IPL

1. This utility bypasses the keyboard buffering logic
and any "trap" of CTRL-ALT-DEL installed by other
software such as PCCACHE (Orchid Technology), or
JBOOT.BIN (Tall Tree Systems), and thus forces an
immediate IPL regardless of their "intercepts", when
this is desirable.

2. A typical use for "IPL" in a batch file is when it
is necessary to change the contents of "CONFIG.SYS"
to add or delete a RAM DISK etc., followed by IPL
to establish the new environment, without requiring
the user to press CTRL-ALT-DEL after the .BAT file
has done its work. The example below illustrates
this technique at the most rudimentary level.

Yourfile.BAT
------------
...
...
:NORAMDISK
COPY \NORAMDSK.SYS \CONFIG.SYS
IPL
:RAMDISK
COPY \RAMDSK.SYS \CONFIG.SYS
IPL
...
...

The above example presumes that the file
NORAMDSK.SYS is a version of CONFIG.SYS which does
not have a DEVICE=VDISK... and the RAMDSK.SYS
file is a CONFIG.SYS which DOES have such a line,
and that the .BAT file "IF" statement has been
used to "GOTO" either the ":NORAMDISK" or ":RAMDISK"
label as desired, based on %1 or ERRORLEVEL etc.
