use the base I/O address of 380h, addresses 380h-

387h must be unused.)

To select an unused I/O address and an IRQ value,

it may be necessary to find out which values are

already in use. To determine your system's current

settings, refer to Appendix A. The ISI551PC is

shipped with the IRQ set to level 3 and the base I/O

address at 2F8 hex. If you are certain that these

settings are not already in use, continue with the

hardware configuration and installation.

Note: If you choose IRQ 3 or 4, you may have to

remove the serial I/Odevice from your

configuration files. The ISI551PC cards do not

allow you to select IRQ 6 because it is almost

universally used for the floppy drive of a

computer. Also, most computers will not be

able to assign IRQ 2 to the ISI because IRQ 2 is

used for slave control.
