Hello, I'm trying to get a Lava DSerial PCI card to work on my B&W G3.
 I did get the card to work on a i386 box (4.0_BETA) by adding some
lines to pucdata.c.

However, on 3.1 macppc, I get:

puc0 at pci1 dev 2 function 0: Lava Computers new serial (com, com)
puc0: couldn't map BAR at offset 0x10
puc0: couldn't map BAR at offset 0x14
pci_intr_map: no mapping for pin C
puc0: couldn't map interrupt

("Lava Computers new serial" Is what I entered into pucdata.c...)

Following is the pcictl dump; unfortunately, I do not understand the
pci magics all that well... anyone here has experience with
puc-attached serial ports?

Is there any way to make OF know about the ports? (It'd be nice to get
console on that but it's not critical... I'd just like to make the
port work normally.)

Any ideas?
Joe.
