CHANGING CONTROLLER OPTIONS FROM THE BIOS
Selecting Controller Options allows you to configure whether RAIDCore arrays may
be bootable, as well as other aspects of the boot process. The default is to configure
an array so that an operating system can boot from the RAIDCore BC4000 Series
RAID controller. If an error occurs, an error message is displayed. However, you
may be booting from the motherboard IDE or another SCSI device in your system. If
this is the case, you should not install INT13 (without INT13, DOS cannot see the
array).
Note: If you configure Boot Mode to install INT13 and to never display an error
message, you will not know during the boot process if an array is degraded or if
other problems have occurred.
One symptom of having too much memory claimed by the option ROMs is a blank
screen with the message "Couldn' t initialize memory" in the top left hand corner.
No additional information is given. This message is coming from the NT Boot
Loader, which requires 512KB of memory free below 640K.
This menu also sets whether you want the boot process to pause when an error
occurs. When the Pause feature is enabled and an array goes critical or offline, or
there is a controller configuration error, the boot process stops, and you must press
Enter to continue booting. This gives you time to view the error message on the
window. If the Pause feature is disabled, the error message is displayed briefly, but
the system continues to boot.
To select a boot option:
1. From the Main menu, select Controller Options.
The Controller Options area is displayed in the BIOS Array Configuration utility
window as shown below. The current settings display in magenta text above the
white selectable options.
