FRB-200U/200/100 User Manual (Ver.1.3, Jun.2008, fmh-001-12) ---- 27
Appendix A.
A.1 The I/O Address Map
The I/O address for the FRB series cards are automatically
assigned by the main board
ROM BIOS. The I/O address can also be
re-assigned by the user. It is strongly recommended that users do not
change the I/O address. The Plug & Play BIOS will effectively perform
the assignment of proper I/O addresses to each FRB series card. The
I/O addresses for the FRB are given in the table below, all of which are
based on the base address of each card.
