Opened: May 16, 2014

Severity: 4-Minor


Invoking the AOM during BIOS Setup or F5 Disk Erase Utility may cause the AOM menu to display incorrectly, or not at all. Additionally, the AOM menu may interfere with the current terminal output, permanently corrupting the appearance of BIOS applications such as Setup or F5 Disk Erase Utility until those applications are exited. The terminal emulator foreground and background colors may be set to black on black, making it impossible to visually navigate the AOM menu. If the AOM menu is exited by pressing the 'q' key, the BIOS Setup or F5 Disk Erase Utility terminal layout may appear corrupt until exited.


AOM console does not display.


While running BIOS Setup or F5 Disk Erase utility over the serial console, press the ESC-( key sequence to invoke the AOM.


Avoid launching AOM during F5 Disk Erase or BIOS Setup. Otherwise, it is advised to have a copy of the AOM menu on-hand when launching the AOM from any BIOS application. See K14594: Accessing the AOM Command Menu (https://support.f5.com/csp/article/K14594). If the AOM menu does not appear to display, it is possible to copy and paste the terminal emulator output into a text editor to see the current state of the AOM menu. It is also possible to force the AOM menu to display by temporarily disabling support for colors in the terminal emulator connected to the serial console.
