Prior to the display of the installation menu, messages similar to the following will occur followed by the kernel panic:
{code}

{code}
h2. Workaround
In order to install the Solaris 10 5/08 release, the kernel must be booted in debug mode via the *kmdb(1)* command so that *cmi_no_init* can be set. Once the Solaris OS is installed, it must be booted this way again and then once logged on, the */etc/system* file must be updated to make this change permanent. These steps are outlined below.
*NOTE:* Before you start, make sure that you have disabled the on-board Broadcom 5709 NIC via the system BIOS since a Solaris driver is not yet available for this NIC. For network connectivity, install a supported alternate NIC in an available PCIe slot. See http://www.sun.com/bigadmin/hcl/data/systems/details/3406.html for supported NIC adaptors as well as other important support information.
h5. Edit GNU GRUB Menu
As the system boots the Solaris 10 5/08 release, the following GNU GRUB menu will be displayed with *Solaris* highlighted as the default OS:
{code}
GNU GRUB version 0.95 (616K lower / 4127168K upper memory)
+-------------------------------------------------------------------+
|Solaris |
|Solaris failsafe | |
+-------------------------------------------------------------------+
Use the ^ and v keys to select which entry is highlighted. Press
enter to boot the selected OS, 'e' to edit the commands before
booting, or 'c' for a command-line.
{code}
\*Press *e* to edit
\*Press *e* again to edit the boot line
\*Append *<SPACE> -kd* to the end of the line and then press *<RETURN>*
\*Press *b* to boot
h5. Enter kmd Command
At the *kmd* prompt *\[0\]>*, enter the *cmi_no_init/W1* command:
{code}
[0]> cmi_no_init/W1
{code}
The system will display:
{code}
cmi_no_init: 0 = 0x1
{code}
Enter *:c* to continue booting:
{code}
[0]> :c
{code}
Note: During this process, if you are not quick enough, you may encounter the following message one or more times:
{code}
kmdb: Do you really want to reboot? (y/n)
{code}
Answer *n* until you get the *\[0\]>* prompt again. Then enter the *cmi_no _init* command and the *:c* command as documented above.
h5. Apply Appropriate Install Time Updates (ITU)
After successfully doing the above, the system will boot and present you with the Solaris installation menu. Choose option *5. Apply driver updates* in order to install the *mega_sas* driver, and if appropriate, the *bnx* driver, both described in _Driver Info_ section on the _IBM x3850 M2 HCL_ listing: http://www.sun.com/bigadmin/hcl/data/systems/details/3406.html.
These are further documented in:
{code}
6651366 Solaris needs native LSI mega_sas driver
6637053 bnx driver should support 5709c chip
{code}
h5. Begin Installation Configuration
After installation of the necessary drivers, press *e <RETURN>* to go back to the install menu. Choose option *4. Solaris Interactive Text (console session)*. This is necessary due to a bug in Xorg and is documented at: http://www.sun.com/bigadmin/jsp/descFile.jsp?url=descAll/6668806_xorg_server
You will eventually be given the option of an automatic reboot or a manual reboot after completion of the install. Choose *Manual Reboot*. This will allow you to update the /etc/system file and set *cmi_no_init* so that it will be unnecessary to boot in kmdb mode on subsequent reboots.
h5. Reboot the System and Update the /etc/system File
After installation completes, if you specified a Manual Reboot after installation, you can now exit to the shell (via *\!*) and edit /a/etc/system to include the following line:
{code}
set cmi_no_init=1
{code}
If you failed to set the system to Manual Reboot and were unable to update the /etc/system file before the system automatically rebooted, then the system will eventually panic on boot. At this point, you will need to reboot the system and perform the procedures documented in the _Edit GNU GRUB Menu_ and _Enter kmd Command_ procedures above in order to boot in kmdb mode. If the install media was not automatically ejected after completion of the installation, you will also need to do so at this time before rebooting the system.
When the system has booted and you have a login prompt, log in as *root* and add the following to */etc/system*:
{code}
set cmi_no_init=1
{code}
Once this is done, it will no longer be necessary on subsequent reboots to go through the kmdb boot procedure documented above.
h6. Launching the Xorg server
The following bug results in a failure to start the Xorg server:
{code}
6668806 Xorg server fails to start on IBM x3850 M2
{code}
In order to successfully start the Xorg server, you will need to create a *xorg.conf* file as documented in http://www.sun.com/bigadmin/jsp/descFile.jsp?url=descAll/6668806_xorg_server.
