Sun Microsystems SPARCengine Ultra AXi - Minimum Requirements; Additional OBP Features in Ultra AXi

D-2 SPARCengine Ultra AX i OEM Technical Manual • May 1999
D.1 Minimum Requirements
The minimum system configuration will have:
■ 64 MB of system memory.
■ A standard I/O (console device)
■ A boot device (storage device or network interface)
■ The OpenBoot Firmware uses NVRAM for OBP environment variables.
■ A console device can be an external terminal connected as Serial Port A (TTYA)
■ A console device can be internal with a keyboard connected to the motherboard
assembly and a monitor with a graphics card (ATI PCI).
If a PCI card is active during the boot process it must have built-in IEEE 1275
compliant plug-in FCode. This allows the device controlled by the card to become
active during the boot process. PCI Cards that do not have the built-in FCode will
allow the system to boot and function normally. For the ATI PCI cards listed on the
IHV web site FCode plug in drivers are included in the OBP on the motherboard
assembly.
OBP requirements are as follows:
■ OBP — 4 MB RAM
■ POST — 4 MB RAM
■ Input-Output (IO) devices such as TTY
