Description
This setting enables or disables the internal
primary and secondary PCI & IDE controllers.
Setting these items to Auto activates the HDD
speed auto-detect function. The PIO mode
specifies the data transfer rate of the HDD. For
example, mode 0 data transfer rate is 3.3MB/s,
mode 1 is 5.2 MB/s, mode 2 is 8.3MB/s, mode 3
is 11.1 MB/s and mode 4 is 16.6MB/s. If your
hard disk performance becomes unstable, you
may manually try the slower mode.
These items allow you to set the Ultra DMA 33/
66/100 mode supported by the hard disk drive
connected to your primary and secondary IDE
connectors.
This allows your hard disk controller to use the
fast block mode to transfer data to and from the
hard disk drive.
