[. . . ] Chapter 3 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 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). [. . . ] OS2 has periodically IRQ8 (RTC) interruptions, If IRQ8 is not set to Disabled, OS/2 may fail to go into Doze/Standby/Suspend mode. Power Management à IRQ [3-7, 9-15], NMI IRQ [3-7, 9-15], NMI Enabled Disabled To enable or disable the detection of IRQ3-7, IRQ9-15 or NMI interrupt events for power down state transition. Power Management à Power Management à Power Management à Power Management à Power Management à Power Management à Power Management à Primary IDE 0 Enabled Disabled Primary IDE 0 Primary IDE 1 Secondary IDE 0 Secondary IDE 1 Floppy Disk Serial Port Parallel Port These items enable or disable the detection of IDE, floppy, serial and parallel port activities for power down state transition. Actually it detects the read/write to/from I/O or address port. 3-22 AWARD BIOS 3. 6 PNP/PCI Configuration Setup The PNP/PCI Configuration Setup allows you to configure the ISA and PCI devices installed in your system. The following screen appears if you select the option "PNP/PCI Configuration Setup" from the main menu. ROM PCI/ISA BIOS (XXXXXXXX) PNP/PCI CONFIGURATION SETUP AWARD SOFTWARE, INC.

If you are using a PnP operating system (such as Windows 95), set this item to Yes to inform BIOS to configure only the resources needed for booting (VGA/IDE or SCSI). The rest of system resources will be allocated by PnP operating system. 3-23 AWARD BIOS PNP/PCI Configuration à Resources Controlled By Resources Controlled by Auto Manual Setting this option to Manual allows you to individually assign the IRQs and DMAs to the ISA and PCI devices. Set this to Auto to enable the autoconfiguration function. PNP/PCI Configuration à Reset Configuration Data Reset Configuration Data Enabled Disabled In case conflict occurs after you assign the IRQs or after you configure your system, you can enable this function, allow your system to automatically reset your configuration and reassign the IRQs. PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à IRQ 3 Legacy ISA PCI/ISA PnP IRQ3 (COM2) IRQ4 (COM1) IRQ5 (Network/Sound or Others) IRQ7 (Printer or Others) IRQ9 (Video or Others) IRQ10 (SCSI or Others) IRQ11 (SCSI or Others) IRQ12 (PS/2 Mouse) IRQ14 (IDE1) IRQ15 (IDE2) If your ISA card is not PnP compatible and requires a special IRQ to support its function, set the selected IRQ to Legacy ISA. This setting informs the PnP BIOS to reserve the selected IRQ for the installed legacy ISA card. Take note that PCI cards are always PnP compatible (except old PCI IDE card). 3-24 AWARD BIOS PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à PNP/PCI Configuration à DMA 0 Legacy ISA PCI/ISA PnP DMA 0 DMA 1 DMA 3 DMA 5 DMA 6 DMA 7 If your ISA card is not PnP compatible and requires a special DMA channel to support its function, set the selected DMA channel to Legacy ISA. This setting informs the PnP BIOS to reserve the selected DMA channel for the installed legacy ISA card. Take note that PCI card does not require DMA channel. PNP/PCI Configuration à PCI IDE IRQ Map To PCI IDE IRQ Map To ISA PCI-Slot1 PCI-Slot2 PCI-Slot3 PCI-Slot4 PCI-Auto Some old PCI IDE add-on cards are not fully PnP compatible. These cards require you to specify the slot in use to enable BIOS to properly configure the PnP resources. This function allows you to select the PCI slot for any PCI IDE add-on card present in your system. Set this item to Auto to allow BIOS to automatically configure the installed PCI IDE card(s). PNP/PCI Configuration à Primary IDE INT# PNP/PCI Configuration à Secondary IDE INT# Primary IDE INT# A B C D These two items, in conjunction with item "PCI IDE IRQ Map To", specify the IRQ routing of the primary or secondary channel of the PCI IDE add-on card (not the onboard IDE). Each PCI slot has four PCI interrupts aligned as listed in the table below. You must specify the slot in the "PCI IDE IRQ Map To", and set the PCI interrupt (INTx) here according to the interrupt connection on the card. PCI Slot Location 1 Location 2 Location 3 Location 4 3-25 AWARD BIOS Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 (if any) (pin A6) INTA INTB INTC INTD INTD (pin B7) INTB INTC INTD INTA INTA (pin A7) INTC INTD INTA INTB INTB (pin B8) INTD INTA INTB INTC INTC PNP/PCI Configuration à Used MEM Base Addr Used MEM base addr N/A C800 CC00 D000 D400 D800 DC00 This item, in conjunction with the "Used MEM Length", lets you set a memory space for non-PnP compatible ISA card. This item specifies the memory base (start address) of the reserved memory space. The memory size is specified in the "Used MEM Length". PNP/PCI Configuration à Used MEM Length Used MEM Length 8K 16K 32K 64K If your ISA card is not PnP compatible and requires special memory space to support its function, specify the memory size in this parameter to inform the PnP BIOS to reserve the specified memory space for installed legacy ISA card. 3. 7 Load Setup Defaults The "Load Setup Defaults" option loads optimized settings for optimum system performance. Optimal settings are relatively safer than the Turbo settings. We recommend you to use the Optimal settings if your system has large memory size and fully loaded with add-on card (for example, a file server using double-sided 8MB SIMM x4 and SCSI plus Network card occupying the PCI and ISA slots). Optimal is not the slowest setting for this mainboard. If you need to verify a unstable problem, you may manually set the parameter in the "BIOS Features Setup" and "Chipset Features Setup" to get slowest and safer setting. 3-26 AWARD BIOS 3. 8 Load Turbo Defaults The "Load Turbo Defaults" option gives better performance than Optimal values. However, Turbo values may not be the best setting of this mainboard but these values are qualified by the AOpen RD and QA department as the reliable settings especially if you have limited loading of add-on card and memory size (for example, a system that contains only a VGA/Sound card and two SIMMs). [. . . ] Of course, we recommend to use AOpen products for best compatibility. Go into BIOS setup, Power Management à Suspend Mode Option, select "Suspend to Disk". 3-36 AWARD BIOS 2. Go into BIOS setup, PNP/PCI Configuration à PnP OS Installed, select "No". This can give BIOS the capability to allocate system resources for Suspend to Hard Drive. [. . . ]
