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 controlling IOAPIC and PCI drivers etc.
