Acer Travelmate 4011Wlmi hidden options

Hey guys

would be possible to uncover or activate options for boot from USB and enabling big (or 48bit) LBA support?
Breaking my head for long time, tried PhoenixBios Editor, can find the LBA option but unfortunately not being able to build proper bios.
Can't find the usb option?
OR I'm really not to skilled for this.
SLIC mode goes without problems.
BIOS:
