[. . . ] [Default is No] If an error occurs during bootup, the BIOS will ask the user to press `F1' to enter the BIOS Setup Utility to repair the problem. [Default is Enabled] If Enabled, the BIOS will display an option to enter the BIOS Setup Utility at bootup. [Default is Enabled] Sets the type of caching algorithm that will be used for the L1 internal cache memory. [Default is Write-Back] Sets the type of caching algorithm that will be used for the L2 external cache memory.

Onboard Device Configuration In this sub-screen, you can enable or disable certain devices as your needs require. [Default is Enabled] Onboard SCSI Onboard SCSI Option ROM 3. 2-F. Event Log Configuration In this sub-screen you can access the log that is created when bootup errors occur. This log will help you troubleshoot any configuration problems you might experience. [Default setting is Disabled] If set to Yes, the event log will be cleared on saving of BIOS settings followed by reboot. By using this option, the events in the Event Log can be organized to help troubleshoot configuration problems.

Processor Serial Number Reserved function. [Default is Disabled] Specifies how the 16k of video ROM is treated at the listed address. Disabled: contents of video ROM are not copied to RAM Enabled: contents of video ROM at listed address segment is copied (shadowed) from ROM to RAM for faster execution. Cached/WP: contents of video ROM from listed address segment are copied from ROM to RAM and can be written to or read from cache memory. [Default is Cached] C000 - C400, 16k Shadow C800 - DC00, 16k Shadow [Default is Disabled] BIOS Act to Deact [Default is 6Clks] Act to Read/Write [Default is 3Clks] Sets length of RAS precharge part of DRAM system memory access cycle when SDRAM system memory is installed.

Plug & Play O/S Reset Config Data PCI Latency Timer Allocate IRQ to PCI VGA Indicates if you are using a PnP O/S. [Default is No] If set to Yes, PCI/PnP data will be stored in Flash on next boot. [. . . ] RAID level 1 is known as mirroring, which stores the data within at least two hard drives, but does not stripe. RAID level 1 also allows for faster access time and fault-tolerance, since either hard drive can be read at the same time. RAID level 0+1 is both striping and mirroring, providing fault-tolerance, striping, and faster access all at the same time. RAM (Random Access Memory): technically refers to a type of memory where any byte can be accessed without touching the adjacent data, is often used to refer to the system's main memory. This memory is available to any program running on the computer. ROM (Read-Only Memory): a storage chip which contains the BIOS; the basic instructions required to boot the computer and start up the operating system. SCSI (Small Computer Systems Interface): pronounced "scuzzy". [. . . ]
