Allows you to specify disk parameters logical cylinders (max. of 1024), heads (max. of 256), and sectors per track (max. of 63) used by BIOS to translate disk I/O requests. Fields are visible and changeable only when drive translation mode is set to User. Storage Options Removable Media Boot. Enables/disables ability to boot system from removable media. Legacy Diskette Write. Enables/disables ability to write data to legacy diskettes. BIOS DMA Data Transfers. Allows control of BIOS I/O requests. Enable allows read and write with DMA transfers. Disable allows read and write with PIO transfers.

PCI VGA Configuration - Allows selection of VGA controller (if multiple PCI video controllers are installed). Failsafe Boot Block ROM The Boot Block is a flash-protected section of the ROM that contains code that checks for a valid system BIOS image when the system is turned on. - If the system BIOS image is valid, the system starts normally. - If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to: - search remopvable media for BIOS image files. If an appropriate BIOS image is found, it is automatically flashed into the ROM. - start the system from bootable removable media that automaticaly invokes system BIOS upgrade utilities. When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing the video option ROM image is not corrupt, "Boot Block Emergency Recovery Mode" will be displayed on the screen. To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following steps: 1. Remove all removable media removable storage options. 2. Turn off the power. 3. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root directory. Note: The media must be formatted using the FAT 12, FAT 16, or FAT 32 file system. 4. Turn on power to the system. If no appropriate BIOS image is found, the failsafe Boot Block BIOS will attempt to start the system from a bootable device. If no bootable device is found, you will be prompted to insert media containing a BIOS image file or BIOS upgrade utility. If the system successfully reprograms the ROM, the system will automatically restart. Security Functions The system offers independent Power-On and Setup passwords for system and data protection. The Power-On password protects the computer from unauthorized access by prompting the user for a password during power up. The Setup password protects the computer from unauthorized or inadvertent re-configuration of legacy device resource settings or ROM flash upgrade by prompting the user for a password prior to entering the Setup Utility. To establish a password: 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the computer.
