5.3 _9112_Initial
@ Description
A PCI-9112 card is initialized according to the card number. Because the
PCI-9112 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-9112 card has to be initialized by this function
before calling other functions.
Note : Because configuration of PCI-9112 is handled by the system,
there is no jumpers or DMA selection on the PCI boards that
need to be set up by the users.
u Syntax
Visual C++ (Windows-95)
int W_9112_Initial (int card_number, int *base_address, int
*irq_no)
Visual Basic (Windows-95)
W_9112_Initial (ByVal card_number As Long, base_address As Long,
irq_no As Long) As Integer
C/C++ (DOS)
int _9112_Initial (int card_number, int *base_address, int
*irq_no)
u Argument
card_number : the card number to be initialized, only four cards can be
initialized, the card number must be CARD_1, CARD_2,
CARD_3, or CARD_4.
base_address : the I/O port base address of the card, it is asigned by system
BIOS.
irq_no: system will give an available interrupt number to this card automatically.
u Return Code
ERR_NoError, ERR_InvalidBoardNumber
ERR_PCIBiosNotExist, ERR_PCICardNotExist
ERR_PCIIrqNotExist
u Example
#include "9112.h"
main()
{
int errCode;
int baseAddr1, irqNo1;
int baseAddr2, irqNo2;
errCode = _9112_Initial( CARD_1, &baseAddr1, &irqNo1);
if ( errCode != ERR_NoError )
