You can install a full-length ISA adapter in the ISA expansion slot. You can install full-length adapters in all PCI expansion slots. You can install hot-plug PCI adapters in PCI slots 1-4, if your operating system supports this feature. Non-hot-plug PCI adapters can also be installed in these slots. Your server supports 5.0 V and universal PCI adapters; it does not support 3.3 V adapters. Note A universal PCI adapter supports both 3.3 V and 5.0 V operation. Your server uses a rotational interrupt technique to configure PCI adapters. This technique enables you to install a variety of PCI adapters that currently do not support sharing of PCI interrupts. PCI slots 5 and 6 are on the primary PCI bus and PCI slots 1-4 are on the secondary PCI bus. The performance of the PCI adapters depends on the configuration of adapters in your system. 144 Netfinity Server HMM
