Volker Ruppert aa57c0e171 - most important functions of the protected mode PCI BIOS added.
Linux (kernel 2.2.18) is able to use the new features.
  Here is the list of changes:

  * BIOS32 data structure added
  * BIOS32 and protected mode PCI BIOS functions added. The BIOS32 function
    returns a pointer to the PCI BIOS entry point when the service $PCI is
    requested and the PCI hardware is present.
  * Supported 32 bit functions: installation check, find pci device,
    read configuration byte/word/dword, write configuration byte/word/dword
  * real mode PCI BIOS installation check rewritten in assembler to use 32 bit
    registers for the protected mode entry point and the 'PCI ' signature.

  TODO:

  * add missing functions of the PCI BIOS (if necessary)
  * add missing features of the i440FX PCI bridge
  * implement the other parts of the i440FX chipset (PCI-to-ISA bridge,
    PCI IDE controller, USB controller)
