|
|
>You might need to override the DSDT when certain features like battery
|
|
status are incorrectly reported (usually causing error messages to
|
|
syslog). DELL laptops usually need this kind of override. Fixed DSDT
|
|
for many systems are available on the <A
|
|
HREF="http://acpi.sourceforge.net/dsdt/index.php"
|
|
TARGET="_top"
|
|
>DSDT page</A
|
|
>, along with a patch
|
|
that tells the kernel to ignore the BIOS-supplied table but use the
|
|
compiled-in fixed DSDT.</P
|
|
><P
|
|
>Basically you need to copy
|
|
the fixed table into your kernel source with a special filename (or
|
|
modifying the filename in the patch supplied at the <A
|
|
HREF="http://acpi.sourceforge.net/dsdt/index.php"
|
|
TARGET="_top"
|
|
>DSDT page</A
|
|
>)
|
|
This override is quite easy: instead of loading the DSDT table from
|
|
bios, the kernel uses the compiled-in DSDT table. That's all.</P
