hi,

trying to use vista's bitlocker drive encryption with my Asus P5GD2 Deluxe
motherboard which has no TPM chip so i'm trying with encryption key on USB
flash drive... have updated BIOS to latest non-beta version but still have
no communication with flash drive before OS kicks in...
any ideas to get communication with flash drive before OS boot ???

not much help at Asus site

thanks,
mike.

To quote from
http://technet2.microsoft.com/Window...mspx?mfr=true:

The system BIOS (for TPM and non-TPM computers) must support the USB mass
storage device class, including reading small files on a USB flash drive in
the pre-operating-system environment. For more information about USB, see
the USB Mass Storage Bulk-Only and the Mass Storage UFI Command
specifications on the USB Web site
(http://www.usb.org/developers/devclass_docs#approved/).

Probably not too helpful for you, but you might consider contacting Asus to
see if they have an approved BIOS. Also, have you tried different USB
drives? We've noticed in several cases that some drives, while behaving
normally after boot, fail in the pre-OS environment.
