E IDE Interfaces
1 4 B
PCI-bus devices serve as primary and secondary IDE hosts on the coolMONSTER/PM. The controller
supports:
Up to Ultra DMA 100 mode
®
Up to PIO mode 4 timing
®
Multiword DMA mode 1 and 2 with independent timing
®
The controller also supports IDE legacy and IDE native mode configuration. The coolMONSTER/PM
features two IDE interfaces that can drive four hard-disk drives. When two IDE devices share a single
adapter, they are connected in a master/slave, daisy-chain configuration. If only one drive is in the
system, you must set it as the master.

IDE interface 1 is available through Connector X4 (39 pins). This interface is designed in 0.1" grid for
optimal connectivity to a 3.5" hard drive. IDE interface 2 is available through Connector X6 (44 pins.) It
is designed in a 2mm grid for optimal connectivity to a 2.5" hard drive.
There are several accessories available for IDE interface 2 connectivity.
You can use two cables to directly connect a hard disk in a 2.5" form factor (KAB-IDE-2MM, Part Number
96021-0000-00-0) or a 3.5" form factor (KAB-IDE-25, Part Number 96020-0000-00-0).
