Updating Firmware
Use the Loadable Firmware Update (LFU) utility to update system firmware. LFU runs
without any operating system and can update the firmware on any system module. LFU
handles modules on the TLSB bus (for example, the CPU) as well as modules on the
I/O buses (for example, a CI controller on the XMI bus). You are not required to
specify any hardware path information, and the update process is highly automated.
Both the LFU program and the firmware microcode images it writes are supplied on a
CD-ROM. From the SRM console, you start LFU with the boot command. (With
Windows NT systems, you can also start LFU from the Utilities option in AlphaBIOS
Setup, as described in Chapter 8.)
A typical update procedure is:
1. Verify
the
console environment variable setting (must be serial).
2. Boot the LFU CD-ROM. (Use the show config command to find the device name
of the CD-ROM device.)
3. Use the LFU list command to show the revisions of modules that LFU can update
and the revisions of update firmware.
4. Use the LFU update command to write the new firmware.
5. Exit.
