2 PowerPC Open Firmware Quick Start Guide
Display Device
For display on a graphics terminal, a VGA display and a
Þrmware-supported PCI graphics card are required. Please refer
to the
PowerPC Open Firmware Supported PCI Cards Quick Reference
for a listing of supported devices.
For display on a serial terminal, an ANSI-compatible 80x24
terminal or terminal emulator is required.
Memory Requirements
The amount of memory in the system is dynamically identiÞed by
PowerPC Open Firmware and does not require user intervention.
Special modiÞcations are required only if EDO (Extended Data
Out) memory is used.
Refer to the System Installation Guide for details regarding the
physical memory requirements of the system.
EDO Memory Configuration
For systems that do not support EDO memory, the default state of
the
edo-memory? variable is false and must always be false.
For systems supporting EDO memory, Pro2000/200 and
Pro3000/200, PowerPC Open Firmware must be conÞgured to use
the timing values for EDO memory. The default state of the
edo-
memory?
variable must be set to true .
To set the NVRAM variable, at the
ok prompt type:
setenv edo-memory? true and press RETURN .
Reset the system to use the new value.
