I/O Control Registers
6.1
Determining the I/O Address
During the power-on stage, the Plug and Play BIOS will assign an appropriate I/O address to each
PCI-822/826 Series card installed in the system. Each PCI-822/826 Series card includes four fixed ID
numbers that are used to identify the card, and are indicated below:
Model
PCI-822LU
PCI-826LU
Vendor ID
0x10B5
0xE10B5
Device ID
0x3001
0x3001
Sub-Vendor ID
0x2129
0x2129
Sub-Device ID
0x0822
0x0826
The following functions are provided for the PCI-822/826 card:
1.
PCI82x_DriverInit(&wTotalBoards)
This function is used to detect how many PCI-822 and/or PCI-826 cards are installed in the
system, and also records the I/O resource information for the card(s) in the library. The function
is implemented based on the PCI Plug and Play mechanism.
For example:
wTotalBoards = 1
there is only one PCI-822/826 Series card installed in the system
wTotalBoards = 2
there are two PCI-822/826 Series cards installed in the system
