● Enable power-on password prompting during system restarts (warm boots) and power-on. ● Hide or make available the integrated I/O functionality, including the serial, or USB ports, audio, or embedded network interface controller (NIC). Any hidden devices are inaccessible and increase overall system security. ● Enable or disable removable media boot ability. ● Enable or disable removable media write ability (when supported by hardware). ● Replicate your system setup by saving system configuration information on diskette and restoring it on one or more workstations. ● Execute self-tests on specified SATA hard drives (when supported by the drive). BIOS ROM The BIOS of the computer is a collection of machine language programs stored as firmware in ROM. The BIOS ROM includes such functions as POST, PCI device initialization, plug-in-play support, power management activities, and the Computer Setup (F10) Utility. The firmware contained in the BIOS ROM supports the following systems and specifications: ● Microsoft WHQL ● Alert-On-LAN (AOL) and Wake-On-LAN (WOL) ● ACPI 1.0 and OnNow ● SMBIOS 2.3.5 ● PC98/99/00 and NetPC ● PXE boot ROM for the integrated LAN controller ● BIOS Boot Specification 1.01 ● Enhanced Disk Drive Specification 3.0 ● "El Torito" Bootable CD-ROM Format Specification 1.0 ● ATAPI Removable Media Device BIOS Specification 1.0 ● MPS Specification 1.4 (for booting Linux SMP) The BIOS ROM is a 1MB Serial Peripheral Interface (SPI) part. The runtime portion of the BIOS resides in a 128-K block from E0000h to FFFFFh.
