hi. everyone!
I’m porting and rewrite device driver source code AMDXRC II Lite for vxworks to qnx6.30
//PCI 9080
I have problem in this part of source code:

my problem is in this part:

}
else

curr &= PCI_MEMBASE_MASK;
mask&=PCI_MEMBASE_MASK;
}
*/
PCI_BASE_IO ??? 
PCI_IOBASE_MASK ???
PCI_MEMBASE_MASK ???
can you tell me what can i do?, or what are the values of these PCI_BASE …
help me please!!
thanks!.
i’m sorry if my english is bad, i’m learning.
