enabling ACPI on RH 8

enabling ACPI on RH 8

[Polevoy, IgorX]

Hi,
I'm trying to enable ACPI on Linux RH 80 (kernel 2.4.18-14) and to run
acpid.
I succeeded to re-compile and re-boot the kernel with all the
ACPI support options selected, however there is no 
/proc/acpi created (or other signs of ACPI driver is up). 

How do I enable it? 
Has it anything to do with the fact that the APM support is currently
enabled ?

Thanks a lot,
Igor.

dunno what redhat uses, but:

check the boot parameters of your kernel, for instance in
/etc/lilo.conf:
- look for the line which conains the "append" keyword and replace "apm=on"
with "apm=off" and "acpi=off" with "acpi=on".
- save lilo.conf and rerun lilo with "/sbin/lilo".

if you are running grub it is quite similar, look for the aforementioned
parameters and change them.
the important thing is to _not_ have "acpi=off". acpi usually overrides
apm if both are "on" (either explicitly or implicitly).

if this does not help, please send the output of "dmesg" after a fresh
reboot to the list.

well, compiling both, acpi and apm, into your kernel is usually no
problem.

Hi,
after adding kernel options with "append"  the following appeared
in dmesg, reporting that ACPI was enabled OK: 

apm: BIOS version 1.2 Flags 0x0b (Driver version 1.16)
apm: disabled on user request.
Starting kswapd
VFS: Diskquotas version dquot_6.5.0 initialized
 tbxface-0099 [01] Acpi_load_tables      : ACPI Tables successfully

27 Devices found: 27 _STA, 0 _INI
Completing Region and Field initialization:.......
7/9 Regions, 0/0 Fields initialized (196 nodes total)

Still there is no /proc/acpi entry... 
Could be that the problem is now in the old BIOS ? 
Also it reports on reboot about "AWARD Modular BIOS v 4.51PC" and 
"ASUS P2B-N ACPI BIOS Revision 1012", there are no ACPI config options
in BIOS 
setup.

Thanks,
Igor.

                               ^^^^^^^^^^

this is an ancient acpi subsystem, you should try with a recent vanilla
kernel and a recent acpi patch from www.sf.net/projects/acpi

Installed vanilla kernel 2.4.20 with patch acpi-20021212-2.4.20.diff.gz. 
Still no /proc/acpi... ?

Thanks,
Igor.
