2. Print out the values captured by the
eeprom
command. You must have a printed
copy of the configuration values before you install the Solaris 7 operating
environment and begin to update the flash PROM. Type the following:
▼
To Install the Solaris 7 Operating Environment
● Install the Solaris 7 operating environment on your system.
Refer to the Installation Library which is in your Solaris 7 media kit. As the Solaris 7
operating environment is installed, you will be notified whether the flash PROM in
your system needs updating. Installing this Solaris release will provide the software
that can upgrade your system’s flash PROM to the required level.
Making the Flash PROM Write-Enabled
Before you update the OpenBoot firmware, which is contained in the flash PROM,
you must set the front panel keyswitch to the proper position to allow the flash
PROM to be write-enabled.
When the switch is set to the Locked position (
FIGURE 5-1
), the flash PROM is write-
protected. When the switch is set to the On position or to the Diagnostics position,
the flash PROM is write-enabled.
FIGURE 5-1
shows the keyswitch positions on a 16-slot Sun Enterprise 6000 system.
The server systems described in this section have the same keyswitch positions.
▼
To Write Enable the Flash PROM
● Turn the keyswitch to the On or Diagnostics position (
FIGURE 5-1
) before updating
the flash PROM.
Note – Disabling write-protection on servers assumes that the system’s write-
protect/enable jumpers were set in the default position (enabled). If you previously
removed the write-protect/enable jumper, perform the steps to make the flash
PROM write enabled in “Location of Flash PROM Jumpers in Sun Enterprise Server
Systems” on page 97.
