4.7 Connect Devices and Power Supply
All the connectors showed in this section are not jumpers, DO NOT
PLACE JUMPER CAPS OVER THE PINS OF THEM. If you do so, you
will damage the motherboard permanently.
4.7.1 Primary / Secondary IDE Connectors (IDE0 / IDE1)
This motherboard provides two independent Ultra ATA/66 IDE channels, which
doubles the ATA/33 burst data transfer rate to 66 MB/s and are 100 percent
backward compatible with all existing ATA / ATAPI devices. These connectors
also support ZIP and LS-120 devices.
The ATA/66 requires a special 40-pin, 80-conductor cable that reduces noise
bleed-over and improves signal integrity by providing 40 additional ground
lines between each of the standard 40-pin ATA (IDE) signal lines and ground
lines. Although a new 40-pin, 80-conductor cable is required for Ultra ATA/66,
the chipset pin connector remains the same at 40.
The 40-pin, 80-conductor cables will support the Cable Detect feature. The
blue (end) connector should be connected to the system board. The black
(end) connector is known as the master position. The gray (middle)
connector can be used for slave devices.
A legacy ATA (IDE) drive can coexist with an Ultra ATA/66 drive. However,
for the Ultra ATA/66 device to attain Ultra DMA 4 mode, an Ultra ATA/66
capable cable is required.
