"As I can remember, Linux uses BIOS only at the bootup time, after that on a
running kernel, there is no role of BIOS routines."

There is also the Video BIOS area which may be used by X (or others) for
displaying graphics when no native drivers are available.
Also, if USB Legacy mode is enabled there may be background SMIs that are
generated to break into the BIOS System Management Mode and provide legacy
support for keyboa
Greg,
you are right about Intel AHCI, I also had to change it once in BIOS for
detecting some Intel's SSD drives. But I think that was again for boot time
hardware initialization. Are you sure that these parameters are accessed
from BIOS routines on a running Linux kernel?

As I can remember, Linux uses BIOS only at the bootup time, after that on a
running kernel, there is no role of BIOS routines. Please refer to
Understanding Linux Kernel for specific details. It also has one appendix on
Linux Boot-up sequence which depends on BIOS. Linux has its own drivers for

Hi list,
I am just exploring how much the linux is dependent on BIOS. I wanted to know :
1. Which information linux uses from BIOS ( some sort of tables like
MP tables, ACPI tables) and for what purpose?
2. Whether linux uses BIOS routines to program and initialize the
different chips (e.g. IOAPI
