Integrated Peripherals Menu Default Screen VIA OnChip IDE Device: This item can let you sets several items concerning the VIA OnChip IDE device parameters. Figure 3-6B. VIA OnChip IDE Device Screen KR7A-133/KR7A-133R Introducing the BIOS 3-21 IDE Prefetch Mode: Two options are available: Disabled or Enabled. 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. 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. " Master Drive Ultra DMA: 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 100 MB/sec. !Disabled: If you encounter the problem of using Ultra DMA devices, you can try to set this item to Disabled. !Auto: When you select Auto, the system automatically determines the optimal data transfer rate for each IDE device. (Default) " Slave Drive Ultra DMA: !Disabled: If you encounter the problem of using Ultra DMA devices, you can try to set this item to Disabled. !Auto: When you select Auto, the system automatically determines the optimal data transfer rate for each IDE device. (Default) 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". PIO MODE 0~4 reflects the IDE device data transfer rate. The higher the MODE value is, the better the IDE device data transfer rate. However, it does not mean that the highest MODE value can be selected. You first have to be sure that your IDE device supports this MODE. Otherwise, the hard disk will not be able to operate normally. User's Manual 3-22 Chapter 3 Super IO Device: This item can let you sets several items concerning the Super I/O device parameters.
