If you are using an audio add-in card, set this field to Disabled. OnChip Modem By default, this field is set to Auto - the onboard modem controller enabled. If you are using a modem add-in card, set this field to Disabled. Memory Parity/ECC Check If you are using x72 (72-bit) PC SDRAM DIMMs, which are DIMMs that support the ECC (Error Checking and Correction) function, set this field to Enabled. 52 Award BIOS Setup Utility 3. 1. 4 Integrated Peripherals CMOS Setup Utility - Copyright (C) 1984-2000 Award Software Integrated Peripherals On-Chip Primary IDE Enabled On-Chip Secondary IDE Enabled IDE Prefetch Mode Enabled IDE Primary Master PIO Auto IDE Primary Slave PIO Auto IDE Secondary Master PIO Auto IDE Secondary Slave PIO Auto IDE Primary Master UDMA Auto IDE Primary Slave UDMA Auto IDE Secondary Master UDMA Auto IDE Secondary Slave UDMA Auto Init Display First PCI Slot IDE HDD Block Mode Enabled Onboard FDD Controller Enabled Onboard Serial Port 1 3F8/IRQ4 Onboard Serial Port 2 2F8/IRQ3 UART2 Mode Select Standard Half X IR Function Duplex No, Yes X TX, RX Inverting Enable Onboard Parallel Port 378/IRQ7 Parallel Port Mode ECP/EPP ECP Mode UseEnter:Select +/-/PU/PD:Value F10:Save DMA 3 Move EPP Mode Select F5:Previous Values EPP1. 7 F6:Fail-Safe Defaults Onboard Legacy Audio Enabled Sound Blaster Disabled SB I/O Base Address 220H SB IRQ Select IRQ 5 SB DMA Select DMA 1 MPU-401 Disabled MPU-401 I/O Address 330-333H Enabled Game Port (200-207H) Item Help Menu Level 3 ESC:Exit F1:General Help F7:Optimized Defaults The screen above list all the fields available in the Integr ated Peripherals submenu, for ease of reference in this manual. In the actual CMOS setup, you have to use the scroll bar to view the fields. The settings on the screen are for reference only. Your version may not be identical to this one. On-Chip Primary IDE and On-Chip Secondary IDE These fields allow you to enable or disable the primary and secondary IDE controller. Select Disabled if you want to add a different hard drive controller. IDE Prefetch Mode This allows data and addresses to be stored in the internal buffer of the chip, thus reducing access time. Enable this field to achieve better performance. IDE Primary Master/Slave PIO and IDE Secondary Master/Slave PIO PIO means Programmed Input/Output. Rather than have the BIOS issue a series of commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and 53 3 Award BIOS Setup Utility then let the controller and the CPU perform the complete task by themselves. Your system suppor ts five modes, 0 (default) to 4, which primarily differ in timing. When Auto is selected, the BIOS will select the best available mode after checking your drive. Auto The BIOS will automatically set the system according to your hard disk drives timing. Mode 0-4 You can select a mode that matches your hard disk drives timing. Caution: Do not use the wrong setting or you will have drive errors. IDE Primary Master/Slave UDMA and IDE Secondary Master/ Slave UDMA These fields allow you to set the Ultra DMA in use. When Auto is selected, the BIOS will select the best available option after checking your hard drive or CD-ROM. Auto The BIOS will automatically detect the settings for you. [. . . ] If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to format. Parallel Port The parallel printer doesnt respond when you try to print. Make sure that your printer is turned on and that the printer is on-line. Make sure your software is configured for the right type of printer attached. [. . . ]
