Broken DSDT table

lebabyg · 12-10-2006, 07:27 PM

Hey Guys,

My DSDT table is pretty much fcukd, so i decided to try and compile a new one. Got the iasl compiler from intel and downloaded a custom dsdt table from http://acpi.sourceforge.net/dsdt/index.php in the form of MYCUSTOMTABLE.asl.gz. I've gunzipped the file but when i try to compile it with iasl i get the error

Error 4061 - Invalid characters found in file

Anybody got any ideas?? The command i am using is iasl -sa /path/to /HP_Compaq-nx6325-F.04-original.asl

Cheers

Try iasl -tc /path/to/file.

Yer i tried that but it didn't work. I think that the version i downloaded is a bit messed up because i tried other versions for other mobos and they compiled fine. I managed to edit the DSDT table and remove the errors though, but i can't work out how to get my bios to load it using mkinitrd. Any suggestions??
Cheers

Graham,
I don't use an initrd, so I just rolled the new DSDT straight into my kernel. I don't know if you've compiled your own kernel or not, so I'll briefly describe how I did it. If you've never made a custom kernel, make sure you look before you leap.

Code:

$sudo cp /path/to/dsdt.hex /usr/src/linux-2.6.18/include/acpi/dsdt_table.h
$ cd /usr/src/linux
$ su
$ <passwd>
# make xconfig

In the configuration dialog, go to

Code:

Device Drivers -->Generic Driver Options

and DISABLE "Select only drivers that don't need compile-time external firmware" and "Prevent firmware from being built."

Then go to

Code:

Power management options (ACPI, APM) --> ACPI (Advanced Blah Blah Blah) Support

Enable "Include Custom DSDT" and add

Code:

/usr/src/linux-2.6.18/include/acpi/dsdt_table.h

to the "Custom DSDT Table file to include" field.

Save the new configuration, and compile as per usual.

I have compiled my own kernel before but i couldn't get the dsdt table to load in. I didn't do it exactly the way you said so i'll give it a whirl tomorrow. The problem i had with the custom kernel was that i couldn't get an ndiswrapper module to load for it. Any hints???

I managed to get the DSDT table to load into the kernel as you said. Unfortunately the problems with the ACPI are still there!! Thanks for your help and time Charred. Cheers

Anytime. I'm glad you got it together, sorry it didn't help your problem.
