Option Boards
This section describes how to install and remove
EISA/ISA and PCI option boards. The system board has
four dedicated EISA/ISA bus master expansion slots
and six dedicated PCI bus master expansion slots (see
Figure 5-11).
The high-performance PCI local bus allows the
adoption of newer networking technology, such as ATM
and 100 MB/second Ethernet NICs, with a minimum of
effort and without concern for I/O bottlenecks. The PCI
local bus offers up to 133 MB/second bandwidth.
This combination of PCI and EISA expansion offers
continuing support for existing special function EISA
add-in boards, such as X.25 Multiport Serial cards.
