Installing the Host Adapter

Changing Switches and Jumpers

This table shows all the possible settings of the

AVA-2825 switch block (s1). Default settings are

marked with an asterisk (*).

If you need to change switch settings or the setting of

jumper J7, do it now before you install the host

adapter. Here are some possible reasons for changing

the settings:

Disabling the Floppy Controller

Only one floppy controller can be enabled in your

PC. If you leave the floppy drive cable attached to

the PC’s built-in floppy controller, turn sw1 Off to

disable the AVA-2825 floppy controller. If you con-

nect the floppy drive cable to the host adapter, you

must disable the PC’s floppy controller. (The PC’s

floppy controller may be on a separate option card or

on the PC motherboard. See the PC documentation.)

Disabling the IDE Controller

Only one IDE controller can be enabled in your PC. If

you leave the IDE cable attached to the PC’s IDE con-

troller, turn sw2 On to disable the AVA-2825 IDE con-

troller. If you connect the IDE cable to the AVA-2825,

you must disable the PC’s IDE controller. (The IDE

controller may be on a separate option card or on the

PC motherboard. See the PC documentation.)
