PIN 1 - Master/Slave -------------------- 1 CLOSED Drive is MASTER (default) OPEN Drive is SLAVE When pin 1 installed, the drive will respond as drive #1. When removed, the drive will respond as drive #2. If you have a slave drive, there must be a master, otherwise your system will hang. PIN 2 - PDIAG ------------- 2 CLOSED Active Low PDIAG - This signal is used to signify to a master drive that the slave drive has passed its internal diagnostics, and is ready for operation. The CAM specification call for this signal to be active high, however, the defactor standard is for this line to be active low. When the PDIAG jumper is installed, it is active low. PIN 3 - Reserved ---------------- Spare - This pin is reserved for future requirements. PIN 4 - IOCHRDY --------------- 4 CLOSED IOCHRDY is available IOCHRDY - This signal is used to extend the IOR and IOW phases of data transfer, thereby slowing the system transfer speed to match the drive's maximum buffer rate. This allows a drive of any buffer speed to run in any high speed system. When installed, IOCHRDY is available. PIN 5 - DACK ------------ DACK - This signal is sent by the Host to initiate a DMA transfer once the drive has activated its DRQ signal. PIN 6 - DREQ ------------ This signal is sent by the drive to indicate that it has data ready to send. +--------+----+-------+-------+-------+-------+ |SIGNAL |PIN |AT PIO |AT DMA |XT PIO |XT DMA | +--------+----+-------+-------+-------+-------+ |IOCHRDY | 4 | O--O | O--O | O O | O O | | | | | | | | | |DACK | 5 | O O | O--O | O--O | O O | | | | | | | | | |DREQ | 6 | O O | O--O | O--O | O O | +--------+----+-------+-------+-------+-------+
