IMPORTANT Your HP customer field representative should upgrade your BIOS to version 22.
1. If you change the hardware configuration, the BIOS automatically resets your boot
ordering priorities to factory defaults (i.e. it sets the boot drive to a higher priority boot
device than the CD-ROM drive).
After a hardware configuration change, you can go back into the BIOS SETUP UTILITY
and reset your boot priorities or enable Quiet Boot as a workaround.
To change boot priorities in the BIOS SETUP UTILITY:
a. Press
F2 on bootup to enter the BIOS SETUP UTILITY.
b. Using your right arrow key, highlight BOOT, then use your up and down arrows to
highlight Boot Device Priority and press
Enter to display the menu.
c. Use the instructions on the screen to prioritize your boot options.
d. Enable Quiet Boot in the BIOS Setup Utility if it is not already enabled to avoid
having to modify the default boot order in the future.
To enable Quiet Boot:
a. Use your left and right arrows to highlight BOOT in the BIOS SETUP UTILITY Menu
and press
Enter.
b. Using the up and down arrows, select Enabled in the pop-up menu and press
Enter.
When Quiet Boot is enabled, a splash screen appears on each bootup on which you can
press
Esc to display a screen that allows you to choose your boot order without reentering
the BIOS SETUP UTILITY.
2. During initial installation and with heavy disk usage, you may see the following message:
Kernel panic: aic7xxx: unrecoverable BRKADRINT.
In interrupt handler, not syncing
The default kernel for Red Hat Enterprise Linux Advanced Server 2.1 is 2.4.9-e.3, but you
need version 2.4.9-e. 12 or later. See instructions in “Getting Updates from Red Hat
Network” in this Support Note to install the latest kernel revision.
