Section Four: Setting Jumpers
Before you install the IDE200 controller, you need to set the jumpers
for your configuration. Always turn the system off before attempting
the reconfiguration, removal, or installation of the IDE200 controller.
You can change configurations on the IDE200 controller simply by
moving a jumper or combination of jumpers from one pair of pins to
another. Place the board in front of you, component side up, with the
bracket on your right. The settings are shown default settings for an
IDE200 controller being installed in an IBM AT or compatible. In this
sample installation, the IDE200 is the first I/O support board being
added to the system and is configured as:
Parallel Serial A Serial B
IO Port Address IRQ Port IRQ Port IRQ
0378 (LPT1) IRQ7 COM1 IRQ4 COM2 IRQ3
