IDE/SATA configuration When this submenu is selected, the BIOS automatically detects the presence of the IDE devices and displays the following items: SATA#1 configuration: If Compatible is selected, it sets SATA#1 to legacy compatibility mode, while selecting Enhanced sets SATA#1 to native SATA mode. • Configure SATA#1 as - This feature allows you to select the drive type for SATA#1. The options are IDE, RAID and AHCI. • ICH RAID Code Base - Select Intel or Adaptec to launch the appropriate SATA RAID firmware to configure SATA RAID. SATA#2 configuration: Selecting Enhanced will set SATA#2 to native SATA mode. Primary IDE Master/Slave, Secondary IDE Master/Slave, Third IDE Master, and Fourth IDE Master: These settings allow you to set the parameters of the IDE slots. Press to activate the submenu screen for detailed options of these items. Set the configurations accordingly. Items included in the submenu are: • Type - Select the type of device connected to the system. • LBA/Large Mode - LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In the LBA mode, the maximum drive capacity is 137 GB. For drive capacities over 137 GB, your system must be equipped with a 48-bit LBA mode addressing. If not, contact your manufacturer or install an ATA/133 IDE controller card that supports 48-bit LBA mode. • Block (Multi-Sector Transfer) - Block Mode boosts the IDE drive performance by increasing the amount of data transferred. Only 512 bytes of data can be transferred per interrupt if Block Mode is not used. Block Mode allows transfers of up to 64 KB per interrupt. Select Disabled to allow data to be transferred from and to the device one sector at a time. Select Auto to allow data transfer from and to the device occur multiple sectors at a time if the device supports it. • PIO Mode - The IDE PIO (Programmable I/O) Mode programs timing cycles between the IDE drive and the programmable IDE controller. As the PIO mode increases, the cycle time decreases. Select Description Auto Automatically detect the PIO mode. Use this value if the IDE disk drive support cannot be determined. 0 Use PIO mode 0. It has a data transfer rate of 3.3 MBs. 1 Use PIO mode 1. It has a data transfer rate of 5.2 MBs. 2 Use PIO mode 2. It has a data transfer rate of 8.3 MBs. 3 Use PIO mode 3. It has a data transfer rate of 11.1 MBs. 4 Use PIO mode 4. It has a data transfer bandwidth of 32 bits. Enabled Enable 32-bit data transfer. Chapter 8 65
