[. . . ] This allows multiple operating systems to be used on both IDE and SCSI drives or the primary operating system to boot using a SCSI hard disk drive. Boot Sequence (A, C) This field determines where the system looks first for an operating system. Options are A, C; C, A; A, CDROM, C; CDROM, C, A; D, A; E, A; F, A; C only; LS/ZIP, C; LAN, A, C; and LAN, C, A. The setup default setting, A, C, is to check first the floppy disk and then the hard disk drive. Boot Up Floppy Seek (Disabled) When enabled, the BIOS will seek drive A once. Floppy Disk Access Control (R/W) This allows protection of files from the computer system to be copied to floppy disks by allowing the setting of Read Only to only allow reads from the floppy disk drive but not writes. The setup default R/W allows both reads and writes. IDE HDD Block Mode Sectors (HDD MAX) This field enhances hard disk performance by making multi-sector transfers instead of one sector per transfer. Most IDE drives, except older versions, can utilize this feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32. capability (Disabled) This allows the enabling or disabling of the S. M. A. R. T. Typematic Delay (Msec) (250) This field sets the time interval for displaying the first and second characters. Four delay rate options are available: 250, 500, 750, and 1000. Security Option (System) When you specify a Supervisor Password and/or User Password (explained later in this section), the Security Option field determines when the system prompts for the password. The default setting is System, where the system prompts for the User Password every time you start your system. The other option is Setup, where the system goes through its startup routine unless the Setup utility is called, when the system prompts for the Supervisor Password. ASUS A50 User's Manual IV. BIOS SETUP Chipset Features Setup The "Chipset Features Setup" option controls the configuration of the board's chipset. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Chipset Features Setup EDO Auto Configuration (60ns DRAM) For EDO DRAM only The default setting of 60ns DRAM sets the optimal timings for items 2 through 5 for 60ns DRAM modules. If you are using 70ns DRAM modules, you must change this item to 70ns DRAM. System Memory in section III for DRAM installation information. BIOS Chipset Features 44 SDRAM Configuration (12ns SDRAM) For SDRAM only This sets the optimal timings of settings for items 2­5, depending on the memory modules that you are using. This 8-pin serial EEPROM device stores critical parameter information about the module, such as memory type, size, speed, voltage interface, and module banks. If your DIMM modules are all 10ns SDRAM, you may set this to 10ns SDRAM. [. . . ] IDE (Integrated Drive Electronics) IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/ 33 IDE devices can achieve up to 33MB/Sec transfer. LPT Port (Line Printer Port) Logical device name reserved by DOS for the computer parallel ports. Each LPT port is configured to use a different IRQ and address assignment. [. . . ]
