-B

Force enumeration of bridges of type “OTHER”.

-c

Ignore class code check.

-dbios bios_options

BIOS options, which include:

Description:

The pci-bios server provides PCI BIOS support. You'll have to provide it in your boot image for systems with a PCI BIOS. Invoke seedres before starting pci-bios.

This server creates the /dev/pci device. Wait for it to appear by specifying the following in the buildfile used by mkifs:

pci-bios
waitfor /dev/pci
