How to avoid time delay
Preventive measure
Change settings of “Legacy USB Support” in the BIOS setup menu from
Enabled to Disabled.
Notes on changing settings
Do not change other items in the BIOS setup.
See Chapter 5 “Server Blade Setup” for how to operate the BIOS setup menu. If
you do not apply the preventive measure above, execute the procedures in
Disabled setting in the item “Legacy USB Support” has the following restrictions:
1. Booting from USB devices including USB CD-ROM and USB FD is not
available.
2. Keyboard operation is not available in the GRUB menu at the OS boot.
3. Do not implement the process in the LPAR manager environment. If you do,
LPAR manager cannot be booted.
The restrictions above are effective when the remote KVM function is used.
Thus, temporarily enable the Legacy USB Support in the BIOS setup when
executing the tasks described in restrictions above.
Once the OS is booted, you can use USB devices including USB CD-ROM and
USB FD regardless of the Legacy USB Support setting. Keyboard operation in
the BIOS setup menu and Boot menu is available regardless of the setting.
How to deal with the time delay
If you are not using the preventive measure, be sure to execute the procedure
shown below every time and immediately after the system has booted.
The following is an example of how to check the frequency recognized by the OS at
the boot when an actual CPU clock frequency is 3000 MHz (3.00 GHz).
1. Check the actual CPU clock frequency.
Use /proc/cpuinfo to check the actual CPU clock frequency.
# grep “model name”/proc/cpuinfo
model name : Intel
®
Xeon® CPU E5450 @3.00 GHz
…..
2. Check the CPU clock frequency
Use /var/log/dmesg to check the CPU clock frequency.
# grep “MHz processor”/var/log/dmesg
Detected 3000.264 MHz processor.
correctly recognized.
# grep “MHz processor”/var/log/dmesg
Detected 3122.376 MHz processor.
incorrectly recognized (due to this
problem).
