[. . . ] BIOS SETUP Chip Configuration (scroll down to see more items, as shown here) SDRAM Configuration [By SPD] This sets the optimal timings for items 2­4, depending on the memory modules that you are using. Default setting is [By SPD], which configures items 2­4 by reading the contents in the SPD (Serial Presence Detect) device. The EEPROM on the memory module stores critical parameter information about the module, such as memory type, size, speed, voltage interface, and module banks. Configuration options: [User Define] [7ns (143MHz)] [8ns (125MHz)] [By SPD] 4. BIOS SETUP SDRAM Command Timing [2T] Leave on default setting. Configuration options: [1T] [2T] SDRAM Multi-Banking [On] Leave on default setting. Configuration options: [On] [Off] SDRAM DataIn-Precharge Latency [1T] Leave on default setting. Configuration options: [2T] [1T] Onboard VGA [Enabled] Leave on default setting if you want to use the onboard VGA. Configuration options: [Disabled] [Enabled] Graphics Window Size [64MB] This feature allows you to select the size of mapped memory for AGP graphic data. Configuration options: [Disabled] [1MB] [2MB] [4MB] [8MB] [16MB] [32MB] [64MB] [128MB] [256MB] Memory Hole At 15M-16M [Disabled] This field allows you to reserve an address space for ISA expansion cards that require it. Setting the address space to a particular setting will make that memory space unavailable to the system. Expansion cards can only access memory up to 16MB. Configuration options: [Disabled] [Enabled] Host Memory Write Buffer [1 Line] Leave on default setting. Configuration options: [4 Lines] [1 Line] 4. BIOS SETUP Chip Configuration 62 PCI 2. 2 Support [Disabled] This function allows you to enable or disable PCI 2. 2 features. Configuration options: [Disabled] [Enabled] Passive Release Support [Disabled] Passive release allows the PCI bus to carry out other tasks when it is receiving data from ISA devices. Configuration options: [Disabled] [Enabled] Super I/O Recovery Time [0. 75 us] Leave on default setting. Configuration options: [0. 25 us]. . . [3. 75 us] Onboard PCI IDE Enable [Both] You can select to enable the primary IDE channel, secondary IDE channel, both, or disable both channels. Configuration options: [Both] [Primary] [Secondary] [Disabled] ASUS CUA User's Manual 4. BIOS SETUP 4. 4. 2 I/O Device Configuration Onboard AC-Link Audio Controller [Enabled] [Enabled] allows you to use the onboard audio controller. If you want to use an add-on audio card, set this field to [Disabled]. Configuration options: [Disabled] [Enabled] Floppy Disk Access Control [R/W] When set to [Read Only], this field protects files from being copied to floppy disks by allowing reads from the floppy disk drive but not writes. [. . . ] Flash ROM (or EEPROM) can be reprogrammed with new programs (or BIOS). SCSI (Small Computer System Interface) High speed multi-threaded I/O interface defined by the X3T9. 2 committee of the American National Standards Institute (ANSI) for connecting many peripheral devices. The standard started from 10MBytes/sec to 160MBytes/sec available today. SDRAM (Synchronous DRAM) The SDRAM features a fully synchronous operation referenced to a positive edge clock whereby all operations are synchronized at a clock input which enables the coexistence of high performance and a simple user interface.
