If your IDE hard drive supports block mode (most new drives do), select Enabled for automatic detection of the optimal number of block mode (most new drives do), select Enabled for automatic detection of the optimal number of block read / write per sector where the drive can support.

Modes 0 to 4 will increase performance progressively. In Auto mode, the system automatically determines the best mode for each device. The Choices: Auto (default), Mode0, Mode1, Mode2, Mode3, and Mode4. On-chip Secondary PCI IDE This item allows you to enable or disable the primary/ secondary IDE Channel.

If your hard drive and your system software both support Ultra DMA/100, select Auto to enable BIOS support. The Choices: Auto (default), Disabled. SATA Mode The Choices: IDE (default), RAID, AHCI. 21
