Interrupt request from IDE device. JM330
IDE_CBLID# I TTL 3.3V 5.0V iPD = 31
KΩ
Input from off-module hardware indicating the type of IDE cable
being used. High indicates a 40-pin cable used for legacy IDE
modes. Low indicates that an 80-pin cable with interleaved grounds
is used. Such a cable is required for Ultra-DMA 66, 100 and 133
modes. JM330
