Log:
[FREELDR]: Reset FrldrBootDrive before chainloading in some cases (when the boot drive is
going to change), because ChainLoadBiosBootSectorCode uses FrldrBootDrive for the boot
drive. An alternative would be to pass this boot drive as a parameter to
ChainLoadBiosBootSectorCode... Fixes FreeLdr booting to another drive.
