5.2 _7256 Initial

@ Description

The PCI-7256 cards are initialized according to the card number. Because

the PCI-7256 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-7256 card has to be initialized by this function

before using other functions.

@ Syntax

U16 _7256_Initial (U16 *existCards, PCI_INFO *pciInfo)

@ Argument

existCards :

The number of installed PCI-7256 cards.

The returned value shows how many PCI-7256 cards are

installed in your system.

It is a structure to memorize the PCI bus plug

and play initiallization information which is decided by

p&p BIOS. The PCI_INFO structure is defined in ACL_PCI.H.

The base I/O address and the interrupt channel number is

stored in pciinfo which is for reference.
