NI-PXI-8433板卡的串口设置问题

我使用的卡是PXI-8433/4,使用pci -v后得到的信息是:
Class = Communication (Other)
Vendor ID = 1093h, National Instruments
Device ID = 70edh, Unknown Unknown
PCI index = 0h
Class Codes = 078000h
Revision ID = 0h
Bus number = 4
Device number = 11
Function num = 0
Status Reg = 280h
Command Reg = 117h
Header type = 0h Single-function
BIST = 0h Build-in-self-test not supported
Latency Timer = 20h
Cache Line Size= 8h un-cacheable
PCI Mem Address = d0302000h 32bit length 4096 enabled
Subsystem Vendor ID = 1093h
Subsystem ID = 70edh
Max Lat = 0ns
Min Gnt = 0ns
PCI Int Pin = INT A
Interrupt line = 9
CPU Interrupt = 9h
可是devc-ser8250命令的参数要PCI IO Address,而这个信息里没有,不知道这类板卡该怎么设置?

这个东东是8255互换的吗?
恐怕要自己写一个驱动.
