Step 12 Install Adapter Cards

The Titan-II PCI Pentium EISA motherboard provides full EISA bus mastering adapter card support and full
compatibility with all IBM XT and AT-compatible adapter cards via six EISA expansion slots. The Titan-II PCI
Pentium EISA motherboard also has four PCI Local Bus expansion slots, all capable of bus mastering.
NCR SCSI BIOS
The NCR SCSI BIOS for PCI SCSI Host Adapter cards is part of the Titan-II PCI Pentium EISA motherboard
WINBIOS.
If a PCI SCSI Host Adapter card does not have an onboard SCSI BIOS, WINBIOS automatically provides the NCR
SCSI BIOS on the PCI bus for the SCSI Host Adapter card to use.
PCI Local Bus Expansion Slots
The PCI Local Bus expansion slot sockets are distinctly different than the standard EISA/ISA expansion slot sockets.
These slots obviously accept a different kind of adapter card than the standard EISA/ISA adapter cards. The slots are
much more compact and smaller. PCI Slots 1, 2, 3, and 4 are all master slots.
EISA Adapter Cards
The EISA adapter cards have different fingers on the edge connecters than ISA adapter cards. The EISA expansion
slots have two rows of contacts, one below the other. An ISA (AT-compatible) Adapter Card can be inserted in the
EISA connector only far enough to make contact with the upper row of contacts. The longer fingers on EISA adapter
cards allow contact with the second row of contacts. See the following graphic.
