5.6. IDE Devices Header "IDE1,2"
It is a 40-Pin box header that support standard ATAPI IDE devices.
This is an dual channel IDE controller, a primary and a secondary. Each channel may
support up to two ATAPI IDE devices.
The primary channel has priority to the secondary channel. Within each channel, the
two different devices are distinguished by master and slave relationship. The master
device has priority over the slave device.
When install more than one device in a channel you must set one a master and the
other as its slave device. These device setting are usually determined by a jumper cap
that is on the ATAPI IDE device.
The M81-MX and M81DC-MX motherboard may supports both the Ultra DMA33 and
Ultra DMA66 protocols. The M81L-MX motherboard may only support Ultra DMA33
protocols.
Note : In order to achieve higher data transfer rate, please used a 40-Pin Ultra DMA66
IDE ribbon cable. Please be remember that only M81DC-MX & M81-MX
Motherboard support Ultra DMA66 solution.
