5.4 725X Initialization
@ Description
The PCI-7250 and cPCI-7252 cards are initialized according to the
card number. Because the PCI-7250 has a PCI bus architecture
and meets the plug and play design specification, the IRQ and
base_address (pass-through address) are assigned by the system
BIOS directly. Every PCI-7250 card has to be initialized by this
function before calling any other functions.
Note: Because the configuration of PCI card is handled by the sys-
tem, there are no jumpers or IRQ selection on the PCI board that
needs to be set up by the users.

@ Arguments
existCards
: The number of installed PCI-7250 cards. The
returned value shows how many PCI-7250 cards are installed in
your system.
pciinfo
: It is a structure to memorize the PCI bus plug and play
initialization information, which is decided by the P&P BIOS. The
PCI_INFO structure is defined in ACL_PCI.H. The base I/O
