CPU to PCI Write Buffer Writes from the CPU to the PCI bus are buffered to offset the speed difference between the CPU and PCI bus. Disabled Writes are not buffered therefore the CPU must wait until the write cycle is complete before starting another write cycle. PCI Dynamic Bursting When enabled, every write transaction goes to the write buffer. PCI Master 0 WS Write When enabled, writes to the PCI bus are executed with zero wait state. PCI Delay Transaction When enabled, this function frees up the PCI bus for other PCI masters during the PCI-to-ISA transactions. This allows PCI and ISA buses to be used more efficiently and prevents degradation of performance on the PCI bus when ISA accesses are made. PCI#2 Access #1 Retry Set this field to Enabled if you want to rotate the priority of the PCI masters. AGP Master 1 WS Write Set this field to Enabled to add one clock tick to AGP write operations. Enabled 56 Award BIOS Setup Utility AGP Master 1 WS Read Set this field to Enabled to add one clock tick to AGP read operations. 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. ! 57 !

Disabled Disables the onboard floppy disk controller. Onboard Serial Port 1 and Onboard Serial Port 2 Auto The system will automatically select an I/O address for the onboard serial port 1 and serial port 2. 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4, 2E8/IRQ3 Allows you to manually select an I/O address for the onboard serial port 1 and serial port 2. Disabled Disables the onboard serial por t 1 and/or serial port 2. UART 2 Mode The system board supports IrDA function for wireless connectivity between your computer and peripheral devices. You may not use IrDA (J21) and the COM 2 serial port (J5) at the same time. If you are using the COM 2 serial port, make sure this field is set to Standard. To use the IrDA function, follow the steps below. Connect your IrDA cable to connector J21 on the system board. Set the UART 2 Mode field to the type of IrDA standard supported by your IrDA peripheral/device (HPSIR or ASKIR). For better transmission of data, your IrDA peripheral device must be within a 30o angle and within a distance of 1 meter. [. . . ] Use another diskette with adequate storage space. 91 + Troubleshooting Hard Drive Hard disk failure. Make sure the correct drive type for the hard disk drive has been entered in the BIOS. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave. The master hard drive must have an active/bootable partition. [. . . ]
