Updating Firmware
Use the Loadable Firmware Update (LFU) Utility to update system firm-
ware. LFU runs without any operating system and can update the firm-
ware on any system module. LFU handles modules on the LSB bus (for ex-
ample, 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. You start LFU on DEC 10000 systems by booting
the RRD42. On VAX 10000 systems you start LFU by booting the Info-
Server on your Ethernet.
A typical update procedure is:
1. Boot the LFU CD-ROM.
2. Use the LFU
show
command to indicate modules whose firmware
needs to be updated.
3. Use the LFU
list
command if you want to check the firmware version
numbers on the CD-ROM.
4. Use the LFU
update
command to write the new firmware.
5. Exit.
