[. . . ] Enable or disable Network Server Mode, which allows the computer to boot the operating system when the power-on password is enabled, with or without a keyboard or mouse attached. When attached to the system, the keyboard and mouse remain locked until the power-on password is entered. Select Post Messages Enabled or Disabled to change the display status of Power-On Self-Test (POST) messages. Post Messages Disabled suppresses most POST messages, such as memory count, product name, and other non-error text messages. [. . . ] (For example, a Zip drive can be made bootable by selecting disk emulation. ) Drive Type IDE LS-120 ATAPI Zip drive Emulation Options None (treated as diskette drive) Disk (treated as hard drive) None (treated as Other) Diskette (treated as diskette drive) Disk (treated as hard drive) Transfer Mode (IDE devices only) Specifies the active data transfer mode. Options (subject to device capabilities) are PIO 0, Max PIO, Enhanced DMA, Ultra DMA 0, and Max UDMA. Support for Computer Setup options may vary depending on your specific hardware configuration. Continued Computer Setup Guide 5 Computer Setup Continued Heading Storage (continued) Option Device Configuration (continued) Description Translation Mode (IDE disks only) Lets you select the translation mode to be used for the device. This enables the BIOS to access disks partitioned and formatted on other systems and may be necessary for users of older versions of UNIX (e. g. , SCO UNIX version 3. 2). Options are Bit-Shift, LBA Assisted, User, and None. CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not be changed. If the selected translation mode is not compatible with the translation mode that was active when the disk was partitioned and formatted, the data on the disk will be inaccessible. Translation Parameters (IDE Disks only) Allows you to specify the parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate disk I/O requests (from the operating system or an application) into terms the hard drive can accept. These fields are only visible and changeable when the drive translation mode is set to User. Multisector Transfers (IDE ATA devices only) Specifies how many sectors are transferred per multisector PIO operation. Quiet Drive (available on select drives only) · Performance Allows the drive to operate at maximum performance. When set to Quiet, the drive will not operate at maximum performance. · Note: If the drive does not support Quiet mode, the Quiet Drive option will not be displayed. Support for Computer Setup options may vary depending on your specific hardware configuration. Continued 6 Computer Setup Computer Setup Continued Heading Storage (continued) Option Options Description Removable Media Boot Enables/disables ability to boot the system from removable media. Note: After saving changes to Removable Media Boot, the computer will restart. Removable Media Write Enables/disables ability to write data to removable media. Note: This feature applies only to legacy diskette, IDE LS-120 Superdisk, and IDE PD-CD drives. Primary IDE Controller Allows you to enable or disable the primary IDE controller. Secondary IDE Controller Allows you to enable or disable the secondary IDE controller. Diskette MBR Validation Allows you to enable or disable strict validation of the diskette Master Boot Record (MBR). Note: If you use a bootable diskette image that you know to be valid, and it does not boot with Diskette MBR Validation enabled, you may need to disable this option in order to use the diskette. Support for Computer Setup options may vary depending on your specific hardware configuration. Continued Computer Setup Guide 7 Computer Setup Continued Heading Storage (continued) Option IDE DPS Self-Test Description Allows you to execute self-tests on IDE hard drives capable of performing the Drive Protection System (DPS) self-tests. Note: This selection will only appear when at least one drive capable of performing the IDE DPS selftests is attached to the system. Hard Drive Order (supported on select models only) SCSI Narrow Termination (supported on select models only) Allows you to specify the order of attached hard drive controllers. The first hard drive controller in the order will have priority in the boot sequence and will be recognized as drive C (if any devices are attached). Allows you to configure SCSI termination on the external SCSI connector for narrow SCSI drives. This feature should only be enabled if you are using a narrow SCSI drive to terminate the external SCSI channel. Allows you to specify the order in which attached peripheral devices (such as diskette drive, hard drive, CD-ROM, or network interface card) are checked for a bootable operating system image. [. . . ] Allows you to reconfigure IRQ settings for these devices or to disable them entirely. PCI Devices Support for Computer Setup options may vary depending on your specific hardware configuration. * These options should be used by advanced users only. Continued Computer Setup Guide 13 Computer Setup Continued Heading Advanced* (continued) Option Bus Options Description Allows you to enable or disable: · · PCI bus mastering, which allows a PCI device to take control of the PCI bus PCI VGA palette snooping, which sets the VGA palette snooping bit in PCI configuration space; this is only needed with more than one graphics controller installed PCI SERR# Generation ECC support allows hardware based error correction for ECC capable memories Printer mode (bi-directional, EPP & ECP, output only) Num Lock state at power-on (off/on) PME (power management event) wakeup events (enable/disable) Processor cache (enable/disable) Processor Number (enable/disable) for Pentium III processors. S3 is an ACPI (advanced configuration and power interface) sleep state that some add-in hardware options may not support. This feature reruns the video option ROM on a boot from the S3 state. · · Device Options Allows you to set: · · · · · · · · Support for Computer Setup options may vary depending on your specific hardware configuration.
