IBM PowerPC products do not have a BIOS as typical intel-based architectures do.

Excerpt from

Open Firmware (also, OpenBoot) is a hardware-independent firmware (computer software which loads the operating system), developed by Sun Microsystems, and used in post-NuBus PowerPC-based Apple Macintosh computers, Sun Microsystems SPARC based workstations and servers, IBM POWER systems, and PegasosPPC systems, among others. On those computers, Open Firmware fulfills the same tasks as BIOS does on PC computers.
It is accessed by a user by a Forth-based shell interface. Forth is a powerful high level language. For example, it is possible to program Open Firmware to solve the Tower of Hanoi problem.[1]
It was going to be described by IEEE standard IEEE-1275, which was not reaffirmed by the OFWG and has been officially withdrawn by IEEE. Unfortunately, this means it is unavailable from the IEEE.


Steps To Reproduce

1. Boot the system under test into OpenFirmare (several methods available ... will find specific instructions)

1. Boot the netboot.img from OpenFirmware by typing: boot network:,\ppc\rhel4u3

Expected Results

1. System should boot and start anaconda loader without error 1. System can transition to stage#2 anaconda
