biosdevname in its simplest form takes a kernel device name as an

argument, and returns the BIOS-given name it "should" be.  This is

necessary on systems where the BIOS name for a given device (e.g. the

label on the chassis is "Gb1") doesn't map directly and obviously to

the kernel name (e.g. eth0).

The distro-patches/sles10/ directory contains a patch needed to

integrate biosdevname into the SLES10 udev ethernet naming rules.

This also works as a straight udev rule.  On RHEL4, that looks like:

KERNEL=="eth*", ACTION=="add", PROGRAM="/sbin/biosdevname -i %k", NAME="%c"

This makes use of various BIOS-provided tables:

PCI Confuration Space

PCI IRQ Routing Table ($PIR)

PCMCIA Card Information Structure

SMBIOS 2.6 Type 9, Type 41, and HP OEM-specific types

therefore it's likely that this will only work well on architectures

that provide such information in their BIOS.
