>Description:
Patch - will use APM API to turn system power off, after the normal halt
proccess. This works with my clone motherboard, which has both the AT &
ATX style power connectors, an ATX power supply, and Intel's 82371AB Power
management controller. This has not been tried on any other system that
I'm aware of. YMMV.
Files patched;
/sys/kern/kern_shutdown.c
/sys/i386/apm/apm.c
/sys/i386/include/apm_bios.h
/sys/i386/conf/options.i386
/sys/i386/conf/LINT
/usr/src/sbin/shutdown/shutdown.c
/usr/src/sbin/shutdown/shutdown.8
>How-To-Repeat:
Installation Instructions;
1. copy the text from the "Fix:" section into a file called "apmdiff.seta".
2. execute the script with "sh apmdiff.seta -p", which will extract the patches
into seperate "diff" files, and then call patch for you.
3. cd /usr/src/sbin/shutdown
4. make clean all install clean
5. cd /sys/i386/conf
6. edit your kernel config file and add;
if not already present; "device apm0 at isa?"
"options APM_SHUTDOWN"
7. config YOUR_KERNEL_NAME_HERE
8. cd ../../compile/YOUR_KERNEL_NAME_HERE
9. make depend all install && shutdown -r now
Test Instructions;
1. make sure that you see something like...
"apm0 on xxx"
"apm: found APM BIOS version x.x"
durring your boot sequence... use dmesg if neccessary,
otherwise all of this is for not...
2. pick either option a, or b, depending on your preference
a. shutdown -p now
b. halt -p
3. you shoold see;
The operating system has halted.
Trying to turn the system off...
and nothing else..., if you see
Failed to turn the system off..
Please press any key to reboot.
well... you get the idea... :(

# apmdiff.seta - This file
#
# This is a SETA (self extracting text archive), and can be
# executed by "sh apmdiffs.seta" at the command line.
# Any text above the "#!/bin/sh" line should be removed!
