EXE from your new diskette and select option 1 "Save Current BIOS to File. " Enter the "Current BIOS Revision:" for the file name. Updating BIOS Procedures (only when necessary) IMPORTANT: If "unknown" is displayed after Flash Type -- , the memory chip is not programmable or is not supported with the PnP BIOS and therefore cannot be programmed by the Flash Memory Writer utility. Download an updated ASUS BIOS file from the Internet (WWW or FTP) or a BBS (Bulletin Board Service) (see ASUS CONTACT INFORMATION on page 3 for details) and save to the disk you created earlier. At the "A:\" prompt, type PFLASH and then press <Enter>. Enter 2 "Update BIOS Main Block From File" from the Main Menu or option 2 "Update BIOS Including Boot Block and ESCD" from the Advanced Features Menu if prompted by option 2 of the Main Menu. The program displays a second screen prompting you for the name of the BIOS file. Type in the complete file name and extension of the new BIOS, and then press <Enter>. The utility then updates the BIOS file from disk. If you encounter problems while updating the new BIOS, DO NOT turn off your system since this might prevent your system from booting up. Just repeat the process, and if the problem still persists, update the original BIOS file you saved to disk above. If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need service. After successfully updating the new BIOS file, exit the Flash Memory Writer utility and then reboot. Hold down <Delete> to enter BIOS setup. You must select "Setup Default" to effect the new BIOS, after which you may set the other items from the Main Menu. IV. BIOS (Updating BIOS) 36 ASUS P2L-B User's Manual IV.

Use the Flash Memory Writer utility to download the new BIOS file into the ROM chip as described in detail in this section. [. . . ] The SCSI ID serves two purposes: It uniquely defines each SCSI device on the bus. It determines which device controls the bus when two or more devices try to use it at the same time. SCSI IDs on one channel do not interfere with the IDs on another channel. This applies to two SCSI host adapters that implement different buses as well as dual channels on a single host adapter. You can connect up to seven SCSI devices to the interface card. [. . . ]
