BIOS Issues |
This chapter describes BIOS issues related to the Sun Blade X6250 server module.
After upgrading the BIOS to 3B26, the prtconf command reports reduced amounts of RAM available. For example:
Upgrade to BIOS 3B27 as described in the Sun Integrated Lights Out Manager 3.0 Supplement for Sun Blade X6250 Server Module.
After upgrading the BIOS/ILOM firmware, the REM card might report firmware corruption.
Reset the BIOS password and clear CMOS using jumper J23, as described in the Sun Blade X6250 Server Module Service Manual, in the chapter Resetting the BIOS Password and Clearing CMOS.
| Note - To clear this issue, you must clear CMOS using the jumper. There are other ways to clear CMOS, but they do not correct this problem. |
On systems with SW2.0.2 and BIOS 3B12, the system won’t boot if serial ports 1 and 2 are disabled in the BIOS.
| Note - To avoid this problem, do not disable your serial ports on systems with SW2.0.2. |
2. Press F2 to access the BIOS.
3. When the BIOS main menu appears, select Advanced Settings -> SuperIO Configuration.
4. Enable Serial ports 1 and 2 on this view.
5. Save your settings then exit.
The system should boot normally.
Systems equipped with 64 GB of DIMMs and a PCIe EM card boot slowly. This effects systems equipped with SW2.0.2 and BIOS 3B12, and with the following operating systems:
Upgrade the software to SW2.0.3 and BIOS 3B14.
Remove the PCIe EM card or some of the DIMMs.
| Note - DIMMs must be removed in pairs. |
If no boot device is available in the boot list during startup, the BIOS waits for user intervention.
Please make sure to have a boot device available before starting the server module.
This is fixed in BIOS version 1ADPI40 of software release 1.3.1.

During the BIOS and SP firmware update, the screen might display the message:
Error (0005) : CMOS Checksum Bad Press F2 to run SETUP Press F1 to load default values and continue. |
| Note - The checksum error is not a problem. The message just indicates that the checksum for the new BIOS is different from the original. |
If the console screen does not display a checksum message, you are finished; the system boots.
If the console screen does display a checksum message:
2. When the BIOS main menu appears, press F9.
Pressing F9 loads the defaults. You must do this prior to editing the settings.
3. Change the settings as you wish.
4. Save your settings and exit.
The Adaptec Raid Utility might display characters incorrectly, causing them to scroll past.
Set your terminal type to ANSI.
For some processor configurations, the BIOS Main screen displays an incorrect processor speed.
1. During system startup, press F2 to change BIOS settings.
2. Press F9 to load Optimal defaults and save your setting by pressing F10.
This is fixed with BIOS 1ADPI21C or later.
PCIe ExpressModule option ROM is disabled by default.
To boot from a PCIe ExpressModule, enable the PCIe ExpressModule option ROM in the BIOS. Use the following steps:
1. During system startup, press F2 to change BIOS settings.
2. Navigate to Boot -> Boot Settings Configuration.
3. Select Enable PEM 0/1 FUN* Option ROM.
