APM Kernel README
by Scott Stone <sstone@turbolinux.com>
June 12, 1998
-------------------------------
INFORMATION:
Most newer computers, desktops and notebooks alike, support APM
(Advanced Power Management). This will allow you to have the
operating system automatically turn the computer off at shutdown, turn
off hard disks/video after a certain period of inactivity, and on
notebook computers, show remaining battery life and AC status.
Linux has had APM support for quite some time, however it has a
tendency to crash certain machines (many Compaq-made machines will
crash when the Linux APM driver loads). This is why the APM-capable
kernel is not the standard Linux kernel. Unfortunately, due to the
nature of APM, it cannot be built as a module, so a separate kernel is
required.
INSTALLATION INSTRUCTIONS:
1. Install TurboLinux onto your computer.
2. Mount this CD-ROM with 'mount /mnt/cdrom' (as the root user).
3. Go into /mnt/cdrom/APMKernel and run './install'
4. Reboot the computer.
USAGE:
APM operation is pretty much user-transparent. You can, however, look
at /proc/apm for APM statistics (mostly only useful if you're using a
notebook computer). You can also view your battery life under X
windows with xosview (see the man page for xosview by typing 'man
xosview', for instructions on how to enable the battery meter).
RECOVERING FROM FAILURE:
If the APM driver locks up your machine, you will need to restore your
kernel back to the original TurboLinux kernel. Make and boot the
sysboot disk (instructions are in images/sysboot.doc). When your
system has booted, mount this CD and reinstall the kernel RPM:
rpm -ivh --force /mnt/cdrom/TurboLinux/RPMS/kernel-2.0.33-11TL.i386.rpm
then reboot your system without the sysboot floppy.
