[. . . ] Chapter 4 Award BIOS This chapter tells how to configure the system parameters. You may update your BIOS via AWARD Flash Utility. Important: Because the BIOS code is the most often changed part of the mainboard design, the BIOS information contained in this chapter (especially the Chipset Setup parameters) may be a little different compared to the actual BIOS that came with your mainboard. 3-1 AWARD BIOS 4. 1 Entering the Award BIOS Setup Menu The BIOS setup utility is a segment of codes/routines residing in the BIOS Flash ROM. This routine allows you to configure the system parameters and save the configuration into the 128 byte CMOS area, (normally in the RTC chip or directly in the main chipset). To enter the BIOS Setup, press during POST (Power-On Self Test). [. . . ] Mouse Left: This function allows you wake up the system by clicking left mouse button twice successively. Mouse Right: This function allows you wake up the system by clicking right mouse button twice successively. Caution: To implement Wake On Keyboard/Mouse function, you must set JP28 to Enabled. Caution: Wake On Mouse function applies to PS/2 mouse only. Caution: If you set a Password but forget it, please clear CMOS. 3-15 AWARD BIOS Integrated Peripherals à KB Power On Password KB Power On Password You can specify 1-5 keys as a password. Integrated Peripherals à Hot Key Power On Hot Key Power On Ctrl-F1 Ctrl-F2 Ctrl-F3 Ctrl-F4 Ctrl-F5 Ctrl-F6 Ctrl-F7 Ctrl-F8 Ctrl-F9 Ctrl-F10 Ctrl-F11 Ctrl-F12 If you select "Hot Key" option in "Power On Function" Item, you need to specify a hot key here. Integrated Peripherals à Onboard FDC Controller Onboard FDC Controller Enabled Disabled Setting this parameter to Enabled allows you to connect your floppy disk drives to the onboard floppy disk connector instead of a separate controller card. Change the setting to Disabled if you want to use a separate controller card. 3-16 AWARD BIOS Integrated Peripherals à Onboard Serial Port 1 Integrated Peripherals à Onboard Serial Port 2 Onboard Serial Port 1 Auto 3F8/IRQ4 2F8/IRQ3 3E8/IRQ4 2E8/IRQ3 Disabled This item allow you to assign address and interrupt for the board serial port. Default is Auto. Note: If you are using a network card, make sure that the interrupt does not conflict. Integrated Peripherals à UART Mode Select UART Mode Select IrDA ASKIR Normal This item is configurable only if the "Onboard UART 2" is enabled. This allows you to specify the mode of serial port2. The available mode selections are: · · ASKIR - Select this setting if you installed an Infrared module via IrDA connector (refer to section 2. 3 "Connectors"). This ASKIR setting allows infrared serial communication at a maximum baud rate of 56K baud. HPSIR - Select this setting if you installed an Infrared module in your system via IrDA connector (refer to section 2. 3 "Connectors"). The HPSIR setting allows infrared serial communication at a maximum baud rate of 115K baud. FIR - Select this setting if you installed an Infrared module via IrDA connector (refer to section 2. 3 "Connectors"). This FIR (Fast IR) setting allows infrared serial communication at a maximum baud rate of 4M baud. Normal - Sets serial port 2 to operate in normal mode. This is the default setting. · · 3-17 AWARD BIOS Integrated Peripherals à RxD, TxD Active RxD, TxD Active Hi, Hi Hi, Lo, Lo, Hi Lo, Lo This item is used to select RxD (Receive Data) and TxD (Transmit Data) mode for UART, for instance, IR device, modem, etc. Normally, we suggest you keep the default setting. Please see the documentation that comes with your device. Integrated Peripherals à IR Transmission Delay IR Transmission Delay Enabled Disabled If Enabled is selected, there will be a 4 character delay when SIR is changed from TX mode to RX mode. Integrated Peripherals à Onboard Parallel Port Onboard Parallel Port 3BC/IRQ7 378/IRQ7 278/IRQ5 Disabled This item controls the onboard parallel port address and interrupt. Note: If you are using an I/O card with a parallel port, make sure that the addresses and IRQ do not conflict. Integrated Peripherals à Parallel Port Mode Parallel Port Mode SPP EPP ECP ECP + EPP This item lets you set the parallel port mode. The mode options are SPP (Standard and Bidirection Parallel Port), EPP (Enhanced Parallel Port) and ECP (Extended Parallel Port). SPP is the IBM AT and PS/2 compatible mode. EPP enhances the parallel port throughput by directly writing/reading data to/from parallel port without latch. ECP supports DMA and RLE (Run Length Encoded) compression and decompression. 3-18 AWARD BIOS Integrated Peripherals à EPP Mode Select EPP Mode Select EPP1. 7 EPP1. 9 This item lets you select EPP mode. Integrated Peripherals à ECP Mode Use DMA ECP Mode Use DMA 3 1 This item lets you set the DMA channel of ECP mode. Power Management à PWRON After PWR-Fail PWRON After PWRFail Former-Sts On Off A traditional ATX system should remain at power off stage when AC power resumes from power failure. This design is inconvenient for a network server or workstation, without an UPS, that needs to keep power-on. [. . . ] "Load Setup Defaults" is not the slowest setting for this motherboard. If you need to verify an unstable problem, you may manually set the parameter in the "BIOS Features Setup" and "Chipset Features Setup" to get slowest and safer setting. 4. 11 Load Turbo Defaults The "Load Turbo Defaults" option gives better performance than "Load Setup Defaults". It is provided for the convenience of power user who wants to push the motherboard to get better performance. Turbo setting does not go though all the detail reliability and compatibility test, it is tested only with limited configuration and loading (for example, a system that contains only a VGA card and two DIMMs).
