I am using slackware linux 10.2. My problem is loading the apm kernel module so that my desktop PC gets really shutdown when I type "shutdown -h now". I have uncommented the line "#modprobe apm" in the kernel modules file, but at booting the kernel delivers the following message:

apm:BIOS not found
/lib/modules/2.4.31/kernel/arch/i386/kernel/apm.o.gz: init_module: No such device
/lib/modules/2.4.31/kernel/arch/i386/kernel/apm.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.31/kernel/arch/i386/kernel/apm.o.gz: insmod /lib/modules/2.4.31/kernel/arch/i386/kernel/apm.o.gz failed
/lib/modules/2.4.31/kernel/arch/i386/kernel/apm.o.gz: insmod apm failed

The same error message appers when I try loading the apm module manually, typing "modprobe apm". My motherboard is Intel® Desktop Board D845GERG2 and my BIOS version is RG84510A.86A.0033.P17
I would be very grateful to receive some helpful advice. Thanks in advance, Martin

neweer laptops don't use apm, they use acpi.

I have a desktop PC, not a laptop. what should I do so that my PC really shuts down whenever I type shutdown now?

you are going to have to rebuild your kernel, there is an option under processor type and features > "enable board specific fixups for reboot" try that one
