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. On systems with the "Boot Block Programming" jumper, open the system cabinet to set this jumper to Programmable. 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 turn off your system. On systems with the "Boot Block Programming" jumper, set the jumper back to its default setting of Write Protect. Turn on your computer and press <Delete> to enter BIOS setup.

[. . . ] ASUS PCI SCSI Cards Many SCSI devices including the ASUS PCI-SC860 use a set of onboard active resistors to terminate the devices at the ends automatically. Automatic termination requires that the SCSI devices be connected in a straight linear connection or "chain. " Connect SCSI devices to one or two of the SCSI connectors in a linear "chain" for auto termination of the ASUS PCI-SC860 to be effective. Other formations will cause your SCSI devices to not mount properly. You must use the end of the ribbon cable when using the internal connector(s) to keep a linear path. [. . . ]
