IDE Prefetch Mode:

Two options are available: Disabled or Enabled. The default setting is 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.

IDE HDD Block Mode:

Enable this filed if your IDE hard drive support block mode. Block mode enables BIOS to automatically detect the optimal number of block read and writes per sector that the drive can support and improves the speed of access to IDE devices.
