USB Configuration

The USB Configuration screen allows the user to configure the available USB controller options.
To access this screen from the Main screen, select Advanced > USB Configuration. To move to
another screen, press the <Esc> key to return to the Advanced screen, then select the desired screen.
This screen should display all USB Mass Storage devices which have been detected in the system.
These include USB-attached Hard Disk Drives (HDDs), Floppy Disk Drives (FDDs), CDROM and
DVDROM drives, and USB Flash Memory devices (USB Key, Keyfob, etc).
Each USB Mass Storage device may be set to allow the media emulation for which it is formatted,
or an emulation may be specified. For USB Flash Memory devices in particular, there are some
restrictions:

A USB Key formatted as a CDROM drive will be recognized as an HDD.

A USB Key formatted without a Partition Table will be forced to FDD emulation.

A USB Key formatted with one Partition Table, and less than 528 MB in size, will be forced to FDD
emulation – otherwise if it is 528 MB or greater in size, it will be forced to HDD emulation.
NOTE
USB devices can be "hotplugged" during POST, and will be detected and "beeped". They will be
enumerated and displayed on this screen, though they may not be enumerated as bootable devices.
