Boot the Operating System
PowerPC Open Firmware allows easy booting at the menu level.
The Booting Process
For the Boot, Diagnostic Boot and AutoScan Boot operations, the
NVRAM variables: boot-device, diag-device, and pboot-device-
default are parsed from left to right. The boot operation then
performs an open-dev on each parsed device. If the open-dev is
successful, a boot is performed on the successfully opened device to
the Þlename in the NVRAM variable: boot-Þle, diag-Þle, or boot-
Þle.
The Network Boot operation creates a string using the net-cfg-
method, serveripaddr, clientipaddr, gatewayipaddr, and boot-Þle.
The process then invokes a boot net: command using the created
string.
