help
- 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.

- 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.
