5.3 _7200_Initial

@ Description

A PCI-7200 card is initialized according to the card number.
Because the PCI-7200 is PCI bus architecture and meets the Plug and Play
design, the IRQ and base_address (pass-through address) are assigned
by system BIOS directly. Every PCI-7200 card has to be initialized by this
function before calling other functions.

Note:

Because the configuration of PCI-7200 is handled by the system, there

are no jumpers or DMA selection on the PCI boards that need to be set
up by the users.
