Default Settings
Your host adapter is already configured for the majority of EISA
class computers. The table below lists the default settings of your
host adapter. Refer to Chapter 3, Configuring the Host Adapter for
information on changing any of the settings.
The Onboard Floppy Controller (AHA-2742W and
AHA-2744W Only)
The onboard floppy controller on the AHA-2742W and
AHA-2744W is enabled by default and is controlled by jumper J1.
■
If your floppy diskette drives are already running under
another controller, disable the onboard floppy controller by
removing the jumper connector on jumper J1.
■
To use the onboard floppy controller, leave the jumper connec-
tor installed on jumper J1 and then disable your existing
floppy controller; refer to your computer or floppy controller
user documentation.
