[. . . ] Note that this bit must not be set if the DDR interface is clocked at 66MHz. " Write Data In to Delay: Two options are available: 1 Cycle and 2 Cycle. This item (bit) controls the number of clock cycles that must occur between the last valid write operation and the next read command. When you set it to "1 Cycle", tWTR duration is 1 clock cycle, etc. " Write Recovery Time: Three options are available: 1 Cycle, 2 Cycle and 3 Cycle. This item (bit) controls the number of clock cycles that must occur from the last valid write operation to the earlist time a new Precharge command can be asserted to the same bank. When you set it to "1 Cycle", tWTR duration is 1 clock cycle, etc. " Act Bank A To B CMD Delay (Active Bank A to Active Bank B Command Delay): Two options are available: 2 Cycle and 3 Cycle. This item (bit) controls the number of clock cycle between successive ACTIVE commands to different banks. When you set it to "3 Cycle", tRRD duration is 3 clock cycles, etc. User's Manual 3-20 Chapter 3 3-5. Integrated Peripherals In this menu, you can change the onboard I/O device, I/O port address and other hardware settings. Figure 3-6A. Integrated Peripherals Menu Full Items Screen Onboard IDE-1 Controller: The onboard IDE 1 controller can be set as Enabled or Disabled. " Master Drive PIO Mode: !Auto: The BIOS can auto-detect the transfer mode of the IDE devices in order to set its data transfer rate (Default). You can select the PIO mode from 0 to 4 of the IDE devices in order to set its data transfer rate. " Slave Drive PIO Mode: !Auto: The BIOS can auto-detect the transfer mode of the IDE devices in order to set its data transfer rate (Default). You can select the PIO mode from 0 to 4 of the IDE devices in order to set its data transfer rate. KG7-Lite/KG7/KG7-RAID Introducing the BIOS 3-21 " Master Drive UltraDMA: Ultra DMA is a DMA data transfer protocol that utilizes ATA commands and the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 66 MB/sec. !Auto: When you select Auto, the system automatically determines the optimal data transfer rate for each IDE device. (Default) !Disabled: If you encounter the problem of using Ultra DMA devices, you can try to Disable this item. " Slave Drive UltraDMA: !Auto: When you select Auto, the system automatically determines the optimal data transfer rate for each IDE device. (Default) !Disabled: If you encounter the problem of using Ultra DMA devices, you can try to Disabled this item. Onboard IDE-2 Controller: The onboard IDE 2 controller can be set as Enabled or Disabled. Description is the same as the item "Onboard IDE-1 Controller", you can refer the above description. The higher the MODE value is, the better is the IDE device data transfer rate. But it does not mean that you can select the highest MODE value just as you like, you first have to be sure that your IDE device supports this MODE, otherwise the hard disk will not be able to operate normally. The onboard IDE drive interfaces supports IDE prefetching, for faster drive accesses. If you install a primary and/or secondary add-in IDE interface, set this field to Disabled if the interface does not support prefetching. When you install more than one display cards, you can choose either a PCI display card (PCI Slot) or an AGP display card (AGP) to activate the display boot-up screen. If you only installed one display card, the BIOS will detect which slot (AGP or PCI) you installed it, in then everything will be take care of by the BIOS.
