1.2 Firmware and Utilities Overview
Firmware residing in ROM on CPU and other modules in the system
provides commands for booting the operating system, testing devices
and I/O adapters, and other tasks useful in operating and maintaining
a running system. You type commands at the console device.
SRM Console
Systems running the Tru64 UNIX or OpenVMS operating systems are
configured from the SRM console, a command-line interface (CLI). From the
CLI you can enter commands to configure the system, view the system
configuration, and boot the system.
System Control Manager (SCM)
The SCM firmware allows the user to access the system remotely. In addition,
the SCM:
• Monitors and notifies the user of power or temperature alert conditions
• Controls initial system power-up
• Manages hard partitions
LFU (Loadable Firmware Update Utility)
You can boot this utility (with the SRM boot command) whenever you need to
update the SRM console firmware or I/O device firmware. The CD with the
AlphaServer firmware is updated periodically.
