PP 41x/03x 4-1
4 MASS STORAGE INTERFACES
The PP 41x/03x board has four interfaces that can be used to attach mass storage devices:
• Two Serial ATA (SATA) interfaces, which are accessible via the CompactPCI J5 connector.
• The Primary EIDE (ATA100) interface supporting the on-board Mass Storage option kits.
• The Secondary EIDE (ATA100) interface connected to the on-board Compact Flash site.
The order in which the PC BIOS firmware tries to boot-load from these drives can be changed via
the BIOS Setup screen for Boot.
4.1 EIDE Interfaces
The board supports two EIDE (ATA100) interfaces.
The Primary EIDE interface (also identified as IDE Channel 0) connects to a 44-pin header for use
by the optional Hard Disk or CompactFlash Mass Storage Kits. Up to two EIDE peripherals may be
connected to this interface. The Hard Disk kit will appear as the IDE Channel 0 Master device.
The CompactFlash modules on the CompactFlash kit will appear as the IDE Channel 0 Master and
IDE Channel 0 Slave devices.
The BIOS Setup screens for Main | IDE Channel 0 Master and Main | IDE Channel 0
Slave allow the user to see what is connected to this interface, and to select some characteristics
of the drives manually. Normally the PC BIOS firmware will automatically determine the drive
characteristics from the drives themselves.
The Secondary EIDE interface (also identified as IDE Channel 1) connects to the on-board
CompactFlash socket. The CompactFlash module will appear as the IDE Channel 1 Master device.
The BIOS Setup screen for Main | IDE Channel 1 Master allows the user to see what is
connected to this interface, and to select some characteristics of the module manually. Normally
the PC BIOS firmware will automatically determine the module characteristics from the module
itself.
4.2 SATA Interfaces
The board provides two SATA-150 interfaces. These interfaces support maximum transfer rates of
150 Mbytes/s. Each interface supports connection of a single SATA device.
The BIOS Setup screens for Main | SATA Port 1 and Main | SATA Port 2 allow the user
to see what is connected to these interfaces, and to select some characteristics of the drives
manually. Normally the PC BIOS firmware will automatically determine the drive characteristics
from the drives themselves.
