4.9 Miscellaneous Features
4.9.1BIOS ROM
It depends on the platform design architecture (sharer ROM or Non-Sharer ROM,
Intel ME SKU and so on).
Non-Sharer ROM: SBIOS and EC BIOS have each SPI ROM chip separately, the
EEPROM is inside EC BIOS area, BIOS will copy a full set of EEPROM data to
SBIOS ROM at the first POST or EEPROM data is updated to speed up the
EEPROM access.
Sharer ROM: The EC BIOS, EEPROM and SBIOS are all inside one SPI ROM chip.
4.9.2 USB Support
This feature allows the use of a USB keyboard to access BIOS Setup and to be used
in DOS without additional drivers. USB floppy boot and Crisis Recovery from USB
floppy is also supported. The driver provides other USB devices support after loading
the operating system.

The flash utility can be used to program both system and keyboard BIOS at the same
time.
