Server Utilities
2-3
Flash Memory Update Program
All servers have BIOS software in a read-only, non-volatile memory (ROM)
chip. This BIOS initializes hardware and boots the operating system when
the server is turned on. The BIOS also provides access to other services
such as keyboard and disk drives.
Your server comes equipped with flash memory. This means that you can
restore your server's BIOS simply by running the flash memory update
utility. You can also upgrade your server's BIOS to future releases by run-
ning the flash memory update utility along with any flash BIOS update
diskette if necessary.
Only use the flash memory update program to upgrade your server’s BIOS
if you are instructed to do so by an authorized Digital support representa-
tive. The flash memory update program and BIOS updates are available
on the Digital Bulletin Board (BBS).
System Configuration Utility (SCU)
The SCU enables you check or change your server’s configuration. The
SCU is PCI-aware, and complies with both EISA and ISA plug and play
standards. You must run the SCU each time you add, remove, or relocate
an EISA or ISA expansion board. Running the SCU is optional for plug
and play and PCI expansion boards.
Each EISA expansion board comes with a diskette that contains a configu-
ration (.CFG) file. The .CFG file describes the board's characteristics and
the server resources that the board requires. The configuration registers
on PCI and plug and play expansion boards contain the same type of in-
formation that an EISA .CFG file does. Your server’s main logic board also
comes with a .CFG file.
The SCU uses the information provided by .CFG files, configuration regis-
ters, NVRAM, and the information that you enter, to specify a particular
configuration. The SCU then configures the server by writing the configu-
ration information to flash memory.
