FlexPort 42s ISA Installation Guide & Jumper Settings

Topics:

Caution:

To avoid existing PnP hardware setting conflict, please check your system for open IRQ and Addresses.
Assign separate unused Address and IRQ for each port. (The default IRQ {5, 7, 10, 11} might not match your system.) Windows 95 users should check "computer" under "device manager" in the "system" and "control panel." Please use the Installation Worksheet to select IRQs for ports.
Ports may share same IRQ if they are not operating simultaneously.
Relocate jumpers on FlexPort 42 prior to installing the board into your computer.
To disable a port, just remove the Address jumper and IRQ jumper.
