Hi Raylynn,
here are the addresses that you should look at for NuBus Cards:
0xf1000000 - 0xff000000
0xf1000000 - 0xf1ffffff is for NuBus Slot 1 (doesn't exist as far as I
know) and
0xff000000- 0xffffffff is for Slot F (doesn't exist as well).
Valid Slots are 9 - E as far as I know.
My PB 1400 internal ethernet card uses slot E address space (internal
video cards do as well).
It's registers addresses are mapped starting at 0xfe600000.
They are repeated until address 0xfe7fffff.
At the very end of the address space is the NuBus ROM.
The rest of slot E address space has values of 0 or 0001 (from
0xfe400000 - 0xfe5fffff).
I think in slot address space you should increase the address values
you are looking at by 0x00100000. But that's just guessed .
Comm-Slot cards are mapped in the address space of the onboard I/O
devices (at least the comm-slot SONIC cards are).
That is 0x50f00000 - 0x50ffffff.
In the kernel sources in the file arch/ppc/platforms/nbpmac_node.h you
can find the addresses for many of the onboard devices (on my PB 1400 I
found 2 more devices) for the PDM PowerBook and Performa machines.
So if you find registers at other places they are probably the ones you
are searching for.
If there aren't any registers at an address you enter you will get an
error message.
You should then increase the address value in steps of 0x1000.
The additional device registers I found are at 0x50f80000 (PBX memory
controller) and 0x50f96000 (a really interesting one that MacOS uses
when accessing the floppy drive).
At address 0x50f36000 there are registers that seem to always be zero
so I don't know what device they belong to.
I know nothing about the addresses PDS cards use - you could browse the
source of the different macintosh ethernet drivers in the kernel tree.
You also need to know the interrupt the device is using. In the files
nbpmac_pfm.c (Performa) nbpmac_amic.c (PDM) and nbpmac_m2.c (PowerBook)
in arch/ppc/platforms you should be able to find out the interrupt
number that are used for each slot. For comm-slot and PDS cards I don't
know what interrupts they use (SONIC uses the interrupt of slot 9).
In MacsBug you enter addresses without "0x" in front of the values.
Some registers are not accessible with the display page (dp) command.
You can use "db" for byte (8 bit) access, "dw" for word (16 bit) access
and "dl" for long word (32 bit) access.
I hope that will help you to find the addresses of the cards you don't
know.
You might as well use MacsBug to see what addresses a MacOS driver
accesses to but that's a bit more complicated.
You can also disassemble the MacOS driver (with MacsBug but better with
ResEdit).
MacOS drivers are in the DRVR resource of either the System file or the
driver's system extension.

Hi Raylynn,
the TREX driver is deactivated for now on the PB 500.
You would have to find out the I/O and memory addresses of
the PCMCIA expansion module (using MacsBug for exapmle).
Drat! I guess I'll have to learn how to use MacsBug. I
also need to
find the address that the Farallon cards with SMC chipset
use. I have
CommSlot, PDS and PowerBook 1400 cards from Farallon that
use the SMC
chipset and none of them have a NuBus ROM. So the SMC
driver currently
doesn't find them. I'd love to get the PowerBook 1400 card
working.
I just noticed you update to kernel version 2.4.32 also! I
have
success with this kernel on the following so far in addition
to my
Newer Tech upgraded 6100:
PowerBook 1400cs w/ 216 Mhz NewerTech G3 w/512K L2 Cache -
Farallon
Ethernet card with SMC chipset still not recognized.
PowerBook 1400c/133 - No problems
PowerBook 5300ce with Focus SMC chipset Ethernet - No
problems
PowerBook 5300cs - No problems.
Still need to test:
Duo 2300c
PPC upgraded PowerBook 540c w/ PCMCIA
PowerBook 1400cs w/ 250 Mhz NewerTech G3 w/1MB L2 Cache
PowerMac 7100 w/ 240 Mhz NewerTech G3
PowerMac 8100/100
Performa 6290

I've tried the kernel on my P6100 accelerated with a
210Mhz NewerTech MAXPower with similar results. I'll be
upgrading my memory to 136MB shortly now that the
boot-time memory contention appears to be fixed. I'll be
testing on my PowerBook 1400 w/ NewerTech, PowerBook
1400/133, PowerBook 5300ce and Duo 2300 shortly. I
should also be able to test my
PowerBook 540 this weekend as I now have 40MB of RAM for
it and a 1.3GB hard disk. It will be interesting to see
if the PCMCIA on this is supported.
