Owner's Manual

Workaround 1:
Install the Solaris operating system on a disk connected to a SAS 6 or CERC6
controller.
Workaournd 2:
During system installation, select the option not to auto reboot after installation
is complete. When the installation completes, type the following in a UNIX shell
to disable the microcode update:
# mv /a/platform/i86pc/ucode
/a/platform/i86pc/ucode.disabled
If the system has already rebooted after installation, type the following in a UNIX
shell:
# mv /platform/i86pc/ucode
/platform/i86pc/ucode.disabled
If you were unable to perform the workaround during the installation and are not
able to boot the system due to system hanging, you can temporarily disable
multiprocessing that will restore system operation so that you can disable
microcode update from a UNIX shell.
To disable multiprocessing perform the following steps from the Grand Unified
Boot loader (GRUB) menu:
1
Ty p e e to edit your selected Solaris entry.
2 Navigate to the line that begins with kernel.
3 Ty p e e to switch to the GRUB edit mode.
4 Append -kd to the line.
5 Press <Enter> to accept the change.
6 Ty p e b to boot the selected Solaris entry.
7 At the kbmd prompt, type the following command and press <Enter>:
use_mp/W 0 :c
