About Flash PROM Jumpers

The Sun Fire V890 system uses flash PROMs to enable the reprogramming of specific
firmware code blocks held in nonvolatile system memory, and to enable remote
reprogramming of that code by an authorized system administrator over a local area
network. Firmware updates, when required, are available for download from the
SM
SunSolve Online web site at: http://sunsolve.sun.com.
Instructions for performing a firmware update procedure are provided with the
downloaded firmware image.
Several jumpers located on the system I/O board and FC-AL disk backplane affect
flash PROM operation. The jumper locations and settings are provided in the
sections that follow. For an explanation of how each jumper affects the flash PROM
update procedure, refer to the instructions supplied with the firmware image.
