| Linux supports two methods of overriding the BIOS DSDT: |
| |
| CONFIG_ACPI_CUSTOM_DSDT builds the image into the kernel. |
| |
| CONFIG_ACPI_CUSTOM_DSDT_INITRD adds the image to the initrd. |
| |
| When to use these methods is described in detail on the |
| Linux/ACPI home page: |
| http://www.lesswatts.org/projects/acpi/overridingDSDT.php |
| |
| Note that if both options are used, the DSDT supplied |
| by the INITRD method takes precedence. |
| |
| Documentation/initramfs-add-dsdt.sh is provided for convenience |
| for use with the CONFIG_ACPI_CUSTOM_DSDT_INITRD method. |
