Table 22: CompactPCI J1 pin assignments
Note:
1. These signals are not connected.
2. These signals are pulled high on the board.
3. These signals are pulled low on the board.
4. ENUM# can be routed to IRQ 3 or IRQ 9 based on the hardware
configuration. There is a BIOS setting to Enable/Disable the ENUM#
function. It is disabled by the BIOS by default and the factory default
hardware configuration is IRQ 9. To support PICMG 2.1 Hot Swap for
peripheral boards, the backplane should bus all peripheral slots ENUM#
together to the system slot and the ENUM# function enabled in the
BIOS.
