A PCI-X system automatically switches between conventional PCI and PCI-X mode, depending
on the type of adapters installed on the bus segment. If a PCI-X bus segment includes any
conventional PCI adapters, that segment must operate in conventional PCI mode.
Just as with conventional PCI, the operating frequency is adjusted to match that of the slowest
device on the bus. If the bus includes a 33-MHz adapter, the bus must operate at 33 MHz. If only
conventional 66-MHz devices are present, a PCI bus optionally operates in conventional 66-MHz
or 33-MHz mode. The table below illustrates several possible combinations of system and adapter
frequencies:
Understanding RBSU
RBSU is an updateable, "intelligent" configuration utility that is embedded in the server ROM.
The purpose of RBSU is to help you configure certain server hardware settings and prepare your
server for operating system (OS) installation. Like its predecessor, SCU, RBSU allows you to
view and establish server configuration settings during initial system startup, as well as modify
them after the server has been configured.
The Configuration Options table describes some of the configuration options that may be
available through RBSU.
