USB Emulation Mode

Common Options : Auto, Force FDD, Force HDD

Quick Review

This BIOS feature determines if the USB flash drive should be treated as a floppy disk drive or a hard drive. Of course, it only comes into effect if you have a USB flash drive plugged into your computer's USB port when it boots up.

When set to Auto, USB flash drives that are less than 530 MB in size are automatically emulated as floppy disk drives. USB flash drives larger than 530 MB in size will be treated like hard disk drives.

When set to Force FDD , the USB flash drive will emulate a bootable floppy disk drive. This setting is used to force a HDD-formatted drive to boot as a floppy disk (e.g. ZIP drive). This is useful for installing operating systems off bootable USB flash drives.

When set to Force HDD, the USB flash drive will be treated like a hard disk drive, even if it is smaller than 530 MB in size. The BIOS will not check it for boot files.

If you do not intend to boot off your USB flash drive, it is recommended that you set this BIOS feature to HDD. This may speed up the boot-up sequence by skipping the check for boot files in your USB flash drive.
