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.
