EIDE Connectors EIDE1 (CON7)
The EIDE Controller supports PIO, Multi-word (8237 style) DMA, and Ultra DMA modes 0
through 5, and Native Mode IDE on Rear I/O.
The following table sets out the pinout of connector CON7 and details its corresponding signal
names and functions.
Note ...
ATA-66 and ATA-100 are faster timings and require a specialized cable which
has additional grounding wires to reduce reflections, noise, and inductive cou-
pling. This cable also supports all legacy IDE drives.
Due to the rear I/O configuration it is strongly recommended to use only a very
short cable length. The maximum cable length should not exceed 45 cm.
The blue end of the ATA-100 cable must be connected to the motherboard, the
gray connector to the UltraDMA/100 slave device and the black connector to
the UltraDMA/100 master device.
