AL440XL board and problems with power-off

I have an Intel AL440XL board and problems with power-off
If I use kernel 2.4.22 (Knoppix 3.3 and older) the PC turnes off after shut-down with
"halt" command.
By using kernel 2.4.23 (Knoppix 3.4 and newer) the PC don't power-off (also with bootoption noacpi or acpi=off)
- that's my problem.
I compared the APM sources but I can't find any differences.
The ACPI-Modul is not inserted.

Has anyone an idea where the reason is located?
I would like to use a newer Kernel and the PC should turn-off on halt.

What do these say:
dmesg |grep apm
dmesg |grep acpi

What do you have appended in /etc/lilo.conf?

dmesg | grep apm
Kernel command line: BOOT_IMAGE=Knx36_267_a7 ro
root=307 ramdisk_size=100000 init=/etc/init lang=de
apm=power-off nomce
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)

dmesg | grep acpi
You can enable it with acpi=force

lilo.conf
append="ramdisk_size=100000 init=/etc/init lang=de
apm=power-off nomce"

depends:

apm -V
apm version 3.2.1

If your BIOS is acpi capable you could try removing the apm part from lilo.conf, run lilo -v to update it, and try booting with apm=off acpi=force
Have you tried updating the BIOS?

Thanks,
my BIOS is the last available version.
If I remove the apm-module and load acpi=force the computer don't also not power-off.

Hmm, if acpi loads successfully you could check the kernel-parameters.txt for it's options.
Sorry, but I don't know if the file comes with knoppix.
You could also try the noapic cheatcode.
Other than that, try disabling Power Management in the BIOS.

I have tried noapic, acpi=power_off/_on, own kernelbuilds (with the same configoptios for apm) etc.
If I use kernel 2.4.22 the PC turnes off after shut-down with "halt" command.
By using kernel 2.4.23 don't power-off - by using the same bootoptions.
I think I can't solve this problem - but I'm shure I will find any new problem.
Thank you.

Well, that was about all I could think of. Have you tried kanotix which has acpi enabled?
You could also try replacing sysvinit but it's a bit risky, here's a howto for doing it on knoppix 3.3

Thank you,
I will try it. (I have an image of my partition!)
I have also got the tip to look at the makefiles.
But just I my PC is not available for me.
