Installing the System Installing Additional Components Shared slots have card compatibility restrictions. If one of the shared slots is occupied, the card being added to the second slot is limited by the configuration of the occupied slot. If the new card has a slower capability than the current bus configuration, it cannot work. If the new card has a faster capability than the current bus configuration, it only runs at the bus mode and frequency of the current bus configuration. • Slots 7 and 8 are single slots. The maximum capability of each slot is PCI/PCI-X 133 MHz. Only slots 7 and 8 allow 133 MHz, PCI/PCI-X cards to run at full speed. These two slots are not limited by bus-mode, frequency-related incompatibilities. Table 1-11 lists the PCI/PCI-X cards slot frequency and bus mode compatibility for shared slots.

The conditions described in this table apply only to shared slots (slots 3 and 4 on bus number 2, slots 5 and 6 on bus number 3). Slots 7 and 8 are not shared slots. b. Compatible: card is accepted and runs at the frequency shown. c. Incompatible frequency: card does not work. d. Incompatible bus: Card does not work. The new card does not initialize powers off. e. Maximum bus mode and frequency supported on shared slots is PCI-X 66 MHz. Chapter 1 59
