Can someone tell me what this means?


Ive been trying (unsuccessfully) to get ACPI working on my laptop for about a month now, and I think I may have just had a big break, but Im not sure. This is what I get in the text mode of boot



ACPI: Subsystem Revision 20030813
PCI: PCI BIOS revision 2.10 entry at 0xfd7ae
PCI: using configuration 1
Looking for DSDT- Not Found!


And then nothing. It freezes after that. Now that I have tried to enable ACPI again, thats as far as I get. I did try the "force noapic" option in lilo this time as well.

Can anyone tell me what that output means?

I'm no genius when it comes to laptops or acpi but maybe it means that your bios does not support acpi.

Since getting my mac I haven't dabbled in linux for a bit but I'm sure last time I recompiled a linux kernel the acpi option was still marked as slightly new and not brilliantly reliable in all bioses. This message might just mean that your bios does not support acpi, or atleast not linux's implementation of it.

Maybe try using APM for your power management needs?

Alex

P.S. Its been a while since I was last on these boards so be gentle on me.

Id try APM but it doesnt work either, as my laptop is fairly new. I know the ACPI works, but im not sure what the DSDT stuff is. Hopefully someone knows and can help me out, or else I may not be able to run Linux all the time

What distro are you using? The newest Mandrake and SuSE distros support ACPI fairly well. Linux does not support all of the ACPI functions, but battery level and temperature monitoring work. If you are using RedHat, do a search for how other RH users have dealt with the situation.

I have Mandrake, but if it supports it, why cant I get it to work, or what am I doing wrong? Im starting to get somewhat slightly frustrated after a solid month of toying with this.

I use Mandrake 9.1 too, and it was very easy to get acpi working on my laptop. I needed to do this in order to get the sound card to work.

I just copied the default lilo boot with label "linux" that was created when I installed Mandrake, and deleted the bit from the append line where it says "acpi=off".

Do you have the acpid daemon running? I know that with SuSE it is not running by default. I had to manually start it and set it to run at runlevel 5 on boot.

It never runs, or starts, because it says it cant find "proc/acpi/events". It doesnt matter what I do, nothing works, and no one on here has been able to help me solve this.

not meaning to insult your intelligence but need to rule out all possibilities...

Is it compiled into your kernel? or is it as a module and being loaded on boot?

Thats fine Im still new at this

It is a module as far as I know. Ive heard that ACPI comes with the kernel, but it tells me no ACPI support in the kernel. I tried recompiling it with it in there, but that was botched.

Is there something that Im seriously missing, or is it something simple that Ive just overlooked?

EDIT: I guess I should clarify, I installed the ACPI and ACPID rpm's off of the Mandrake cd's. I removed the APM as well

Kramer,
Here is the section of my /var/log/boot.msg file relating to ACPI. Do you have it enabled in your BIOS? The other possibility is an IRQ conflict.

There is no ACPI option in my BIOS, but my BIOS isnt on the blacklist at the sourceforge website. I can post my lilo.conf file later on tonight if you would like

No wait!!!

This is from your file-
<6>ACPI: Subsystem revision 20030228
<6>PCI: PCI BIOS revision 2.10 entry at 0xfd89b, last bus=2
<6>PCI: Using configuration type 1

Ok, this is the point at which mine freezes and gives the error message

Looking for DSDT- Not Found!

After that I have to do a hard shut down, then restart.
Any Ideas?

I have no idea what DSDT is. Have you searched the acpi sourceforge.net site for info on this?
You might also want to check the site of your laptop manufacturer for info on acpi support.

There is something on the ACPI website. I just checked it. Its a patch it looks like. Compaq doesnt offer jack as far as information goes. Their tech support is non existant just FYI On the BIOS note, I know its a Phoenix and the revision if that will help. I have it somewhere, Ill see if I cant find it.

Is there some reason I never get the /proc/acpi when my laptop boots?

I searched Yahoo for DSDT as well, but I have no clue what this stuff means
