System/Core I/O Card Troubleshooting

The System/Core I/O card provides the Multi-Function I/O Control (MFIOC). It also
provides HSC to EISA bus conversion, as well as the physical slots for EISA or HSC I/O
cards.
Core I/O
The MFIOC section of the System/Core I/O card is shown in Figure 3-4. The system/Core
I/O card itself is an FRU, so any failure of a Core I/O component located on the
system/Core I/O card requires the replacement of the system/Core I/O card.
