3.3 The I/O Address Map
The I/O address of OME-PIO/PISO series card is automatically
assigned by the main board ROM BIOS. The I/O address can also be re-
assigned by user. It is strongly recommended not to change the I/O
address by user. The plug & play BIOS will assign proper I/O address to
each OME-PIO/PISO series card very well. The I/O addresses of OME-
PIO-D96 are given as follows:
Address Read Write
Wbase+0 RESET\ control register Same
Wbase+2 Aux control register Same
