Server Software and Utilities
2-2
ServerWORKS Quick Launch
Quick Launch is used to install the server’s Network Operating System (NOS).
In addition to providing quick and seamless NOS installation, Quick Launch also
provides drivers, documentation, and the ability to make diskettes of utilities
such as diagnostics. For more information, refer to the Quick Launch Reference
Guide.
System Configuration Utility (SCU)
The SCU enables you check or change your server’s configuration. The SCU is
PCI-aware, and complies with ISA plug and play standards. You must run the
SCU each time you add, remove, or relocate an ISA expansion board.
Each ISA expansion board comes with a diskette that contains a configuration
(.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 information that an ISA
.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 registers,
NVRAM, and the information that you enter, to specify a particular configuration.
The SCU then configures the server by writing the configuration information to
flash memory.
The SCU stores most of the configuration values in the battery-maintained
memory (NVRAM) of the real-time clock (RTC), and the rest of them in flash
memory. These values take effect each time you boot the server. POST checks
the values against the actual hardware configuration; if they do not agree, it
generates an error message. You must then run the SCU to specify the correct
configuration before you boot the server. POST checks the BIOS Setup.
The SCU modifies the CMOS RAM and NVRAM, under your direction. The
BIOS POST routines and the ISA plug and play Auto Configuration Manager
(ACM) actually configures the hardware.
