IDE Interface (J6)

The ReadyBoard 800 provides one primary IDE connector (J6) for two IDE devices and one
CompactFlash socket (J23) for the secondary IDE controller.
The I/O Hub (Southbridge) EIDE interface logic supports the following features:
•
Transfer rate up to 100Mbps
•
Increased reliability using Ultra DMA 33/66/100 transfer protocols
•
Full scatter-gather capability
•
Supports ATAPI and DVD compliant devices
•
PIO IDE transfers as fast as 14Mbps.
•
Bus master IDE transfers as fast as 66Mbps.
•
Single Bus Master EIDE
• Supports two IDE drives on primary interface and one CompactFlash card on the secondary
Table 3-5 list the signals for the IDE 44-pin, 2mm header.

Digital Ground
Not Connected - Key pin plug
Primary Device DMA Channel Request – Used for DMA transfers between host
and drive (direction of transfer controlled by DIOR* and DIOW*). Also used in
an asynchronous mode with DMACK*. Drive asserts IDRQ0 when ready to
transfer or receive data.
