Version 1YET65WW (1.29)
Note: This BIOS version will only work with Embedded Controller Program Version 1.06 (or higher).
(New) When a system boots with a USB memory key installed, even if the system does not boot to the USB memory key, a DOS drive letter is assigned to a FAT partition. On the previous version of BIOS, the DOS drive letter was assigned only when the system booted from a USB memory key. |
