Configuring Quartet Adapters

Quartet adapters use the resources of a single adapter to provide
four separate Fast Ethernet segments. A Quartet adapter requires a
PCI slot with enough room to accept a full length adapter. Follow
the instructions above for configuring a single port PCI adapter to
install and configure your Quartet.
If you are planning to use the Quartet adapter with Windows NT or
Windows 95, please see the discussion of PCI-to-PCI bridge
chips below.

PCI-to-PCI Bridge Chip

Quartets use the DEC PCI-to-PCI bridge chip to increase the capac-
ity of PCI computers by adding an additional PCI bus to the existing
motherboard. Some older system BIOSs fail to configure a Quartet
adapter properly, because the BIOS does not recognize the PCI-to-
PCI bridge chip. Such BIOSs need to be upgraded with a new BIOS
from the computer manufacturer before the system can be used with
Windows NT or Windows 95.
