4. BIOS Setup 4. BIOS Setup The QS750 motherboard uses AWARD BIOS, which is stored in a Flash EEPROM and can be upgraded by a floppy disk-based program. The BIOS has a built-in Setup Program that allows users to modify the basic system configuration settings. The settings are then stored in a dedicated battery-backed memory, called CMMOS RAM that retains the information when the power is turned off. The BIOS provides critical low-level support for the system’s central processing, memory and I/O subsystems.

4. BIOS Setup A brief description of each highlighted selection appears at the bottom of the screen. CMOS Setup Utility – Copyright © 1984-1999 Award Software.
4. BIOS Setup Load Setup Defaults Setup defaults are factory settings for optimal-performance system operations. Save & Exit Setup Save settings in nonvolatile CMOS RAM and exit Setup. Exit Without Save Abandon all changes and exit Setup. 4.3 Standard CMOS Setup Menu In the Standard CMOS Menu (Figure 2) you can set the system clock and calendar, record disk drive parameters and the video subsystem type, and select the type of errors that stop the BIOS POST.
4. BIOS Setup 4.3.3 Hard Disks The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI drives. NOTE: We recommend that you select type AUTO for all drives. The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.
4. BIOS Setup Ø LBA (Logical Block Addressing): During drive accesses, the IDE controller Ø Transforms the data address described by sector, head, and cylinder number Ø into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders. 4.3.4 Drive A/B type Select the correct specifications for the diskette drive(s) installed in the computer. None No diskette drive installed 360K, 5.
4. BIOS Setup No errors POST does not stop for any errors. All errors If the BIOS detect any non-fatal error, POST stops and prompts you to take corrective action. All, But Keyboard POST does not stop for a keyboard error, but stops for all other errors. All, But Diskette POST does not stop for diskette drive errors, but stops for all other errors. All, But Disk/Key POST does not stop for a keyboard or disk error, but stops for all other errors. 4.3.
4. BIOS Setup 4.4 Advanced BIOS Features Setup Menu This screen (Figure 3) contains industry-standard options additional to the core PC AT BIOS. This section describes all fields offered by Award Software in this screen. Some fields may vary from those in your Setup program. Your system board designer may omit or modify some fields. CMOS Setup Utility – Copyright © 1984-1999 Award Software.
4. BIOS Setup 4.4.3 External Cache Cache memory is an additional memory that is much faster than conventional DRAM(system memory). When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. The External Cache field may not appear if your system does not have external cache memory. 4.4.4 Quick Power On Self Test This allows you to enable or disable system self test when power on. 4.4.
4. BIOS Setup 4.4.11 Boot Up NumLock Status Toggle between On or off to control the state of the NumLock key when the system boots. When toggled on, the numeric keypad generates numbers instead of controlling cursor operations. 4.4.12 Gate A20 Option This entry allows you to select how the gate A20 is handled. The gate A20 is a device used to address memory above 1 Megabytes. Initially, the gate A20 was handled via a pin on the keyboard.
4. BIOS Setup Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8-bit X-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1 MB) available for loading device drivers, etc. Enable shadowing into each section of memory separately.
4. BIOS Setup 4.5 Advanced Chipset Features Setup Menu CMOS Setup Utility – Copyright © 1984-1999 Award Software.
4. BIOS Setup 4.5.5 SDRAM ECC Setting This item allows you to select among three methods of memory error checking: Auto, Enabled and Disabled. 4.5.6 SDRAM CAS Latency The choices are 2 and 3 (default). This feature appears only when SDRAM DIMMs are installed (BIOS auto detection). If the CAS latency of your SDRAM DIMM is 2, choose 2 to enhance the system performance. If the CAS latency of your SDRAM DIMM is 3, stey with the default setting. 4.
4. BIOS Setup 4.6.3 IDE Primary/Secondary Master/Slave UDMA Ultra DMA 33/66 implementation is possible only if your IDE hard drive supports it and the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus master driver). If your hard drive and your system software both support Ultra DMA 33/66, select Auto to enable BIOS support. The Choice: Auto, Disabled. 4.6.4 On-chip Primary PCI IDE The chipset contains a PCI IDE interface with support for two IDE channels.
4. BIOS Setup I/O address. The choice: 3F8/IRQ4, 2E8/IRQ3, 3E8/IRQ4, 2F8/IRQ3, Disabled, Auto. 4.6.11 Onboard Parallel Port This item allows you to determine access onboard parallel port controller with which I/O address. The choice: 378H/IRQ7, 278H/IRQ5, 3BC/IRQ7, Disabled. 4.6.12 Parallel Port Mode (Activated by Onboard Parallel Port) Select an operating mode for the onboard parallel (printer) port. Select Normal unless your hardware and software require one of the other modes offered in this field.

4. BIOS Setup Min Saving Minimum power savings. Inactivity period is 1 hour in each mode (except the hard drive). 4.7.3 Video Off Method Determines the manner in which the monitor is blanked. V/H SYNC+Blank System turns off vertical and horizontal synchronization ports and writes blanks to the video buffer. DPMS Support Select this option if your monitor supports the Display Power Management Signaling (DPMS) standard of the Video Electronics Standards Association (VESA).
4. BIOS Setup an incoming call or not. It requires a PCI add-in network interface card with remote wakeup capabilities. Please set this option to enable RI resume and WOL. 4.7.10 Modem Use IRQ This determines the IRQ in which the MODEM can use.
