Boot Block 32 KB boot block is used for initializing DRAM, checki ng BIOS int egrity, decompressing
POST/Run-Time BIOS, and doing crisis recovery of BIOS if necessary.
Crisis Recovery Recover BI OS from a hard disk, a host PC connected to parallel port, or a proprietary
debug card of ASUS.

via parallel port.
CPU Automati cal ly detect the CPU ty pe and spee d ; Suppo rt CPU host fr equ en cy sel e cti on.
DRAM Support SPD and automatic memory sizing; always shadow VGA BIOS and system
BIOS as well as shadow NIC boot ROM by selection.
Cache Always enable L1 and L2 caches.
Security Unique p assw ord pr ote ctio n for sy stem a nd HDD; dynamic bac kdoor ( mast er) p a sswor d
