[LinuxBIOS] GA-M57SLI-S4 and ACPI

[Andreas B. Mundt]

Hello everybody,

it has been pointed out on the list, that an implementation of ACPI for the
GA-M57SLI-S4 needs to be done in a "cleanroom" to avoid legal issues.

Is it possible to move the ACPI functionality from the BIOS to the linux 
kernel? By extracting the DSDT from the vendor BIOS and preparing a kernel 
with:

CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="/usr/src/linux-source-2.6.21/dsdt.hex"

the user could run linuxbios but the vendor's DSDT as a workaround for the 
time being.

What modifications are necessary in linuxbios to allow for this?
Or do the same legal issues aply?

Thanks,

Andi

you may still need to update dsdt.dsl, because some io range is different....
