VCN700-LIC10/15

 IDE Prefetch Mode

The options: Disabled, Enabled.

 Primary/Secondary Master/Slave PIO/UMDA

The channel has both a master and a slave, making four IDE devices possible. Because

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.

 IDE HDD Block Mode

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.
