Open Firmware and the Device Tree
NewWorld relies heavily on a functioning Open Firmware with a complete device tree. For each device that is supported by a PCI expansion card, the device-tree information is provided by startup code in the expansion ROM on the card. For a discussion of the levels of support such cards can provide, please see the section "Device Configuration" starting on page 32 of
Designing PCI Cards and Drivers for Power Macintosh Computers.
