The DSDT (Differentiated System Description Table) often needs to be
overridden because of broken BIOS implementations. If this feature is
activated you will be able to provide a customized DSDT by adding it
to your initramfs. If your mkinitrd tool does not support this feature
a script is provided in the documentation. For more details see
<file:Documentation/dsdt-initrd.txt> or <http://gaugusch.at/kernel.shtml>.
If there is no table found, it will fall-back to the custom DSDT
in-kernel (if activated) or to the DSDT from the BIOS.
This option supports a custom DSDT by optionally loading it from initrd.
See Documentation/acpi/dsdt-override.txt
Even if you do not need a new one at the moment, you may want to use a
better DSDT later. It is safe to say Y here.
If you are not using this feature now, but may use it later,
it is safe to say Y here.
