Upgrades and Options
Option Boards
This section describes how to install and remove
EISA/ISA and PCI option boards. The system board has
three dedicated EISA/ISA bus master expansion slots,
four dedicated PCI bus master expansion slots, and one
shared PCI/EISA bus master expansion slot (see Figure
5-10). You can install one EISA board or one PCI board
in the shared slot, not both.
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.
