These functions or alive in 16 bit mode (0xf000 segment) We can call this functions in i386 using the pnpbios driver (bioscalls.c). I must call this functions to change the boot order and reboot from linux x86_64 using my driver. I have seen in some forum that we can off the ACPI during the linux boot. Can you help on this? -mkr Alan Cox wrote: >> Actually I want to call the BIOS run time functions as per the >> PNPBIOSSpecification-v1.0a (attached). >> > > We use ACPI for x86_64, which means you need to use the ACPI methods not > the PnPBIOS ones.
