z IDE DMA Transfer Access
Use this field to enable or disable IDE DMA transfer access.
z On-Chip IDE Channel

two IDE devices may have a different Mode timing (0, 1, 2, 3, 4), it is necessary for these to
be independent. The default setting “Auto” will allow auto detection to ensure optimal
performance.

The options: Enabled, Disabled.
z On-Chip SATA Type
The options: Native IDE, RAID, AHCI, Legacy IDE, IDE->AHCI

If the IDE hard drive supports block mode select Enabled for automatic detection of the
optimal number of block read/writes per sector the drive can support.
