Youcan upgrade the BIOS on the blade using the biosupdate utility. This utility
loads a device driver called mtdbios, performs the BIOS update using the slflash
utility,and then unloads the mtdbios driver.
The biosupdate utility is installed on the server blade as part of the PXE boot
installation process. For information on the PXE boot installation, see Chapter 4 of
the Sun Fire B100x and B200x Server Blade Installation and Setup Guide (available on
the CD supplied with the blade).
Caution – When upgrading the BIOS, do not interrupt the process by resetting or
powering down the blade. Interrupting the upgrade will permanently damage the
blade.
Note – If the BIOS upgrade fails, a failuremessage is displayed on the screenand in
/var/log/messages. If this problem occurs do not reset or power offthe blade.
Contact your Sun Beta support manager for advise.
