11.2AM-174 to AM-986 34-Pin X-bus Cabling Instructions
If you are performing a Roadrunner 030 to 040 upgrade, you should completely remove
the two 34-pin X-bus cables from your computer and then reinstall them based on the
instructions in this section. As mentioned earlier, X-bus cabling for the Roadrunner
030 and 040 boards is not the same.
No power is conducted over either of the two 34-pin cables, so no damage will occur if
you accidentally reverse these cables. However, if the cables are not plugged in
correctly, the system will not boot or run self-test. If your computer does not boot after
doing the upgrade, turn off the power and double check your cable connections.
To make the X-bus cable connections between the AM-174 and AM-986 boards, follow
the instructions in the cabling illustrations on the next page:
