another step toward a working driver for Dell 1450 wireless card

Sat Dec 16 13:39:24 PST 2006

     Under FreeBSD 6.1 I have now managed to convert the Windows XP driver
text file (bcmwl5.inf) to ASCII and then run it through ndisgen along with
BCMWL5.SYS to produce a BCMWL5_SYS.ko module, which I've placed into
/boot/modules for loading during the boot/startup procedure.  If I try to
load the module with kldload, the system hangs and then reboots.  If I put

BCMWL5_SYS_load="YES"

into /boot/loader.conf, I get the following:

Automatic reboot in 15 seconds - press a key on the console to abort
[At this point, I pressed a key to keep the above messages from being wiped
 out by a reboot.  --SB]
--> Press a key on the console to reboot,
--> or switch off the system now.

     Note the set of four "No match for" messages early in the boot process,
right after the keyboard is identified.  After those appear, everything looks
normal enough until right after the two lines that say,

firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me)
firewire0: bus manager 0 (me)

At this point, the wireless card is identified, though not entirely correctly.
The card is a 1450, not a 1400.  (Windows XP correctly identifies the card.)
Then a series of 14 identical lines follows that say,

ntoskrnl dummy called...

after which the panic messages appear.
     It's progress of a sort because previously I had never gotten it to do
more than notice that an unidentified network device was at pci2, but with
no driver attached.  But I still do not have working wireless support in
FreeBSD.
     If anyone recognizes any of the weird messages or has any idea where
I may have gone wrong or anything else that might provide a clue to getting
the damned thing to work, I would appreciate hearing from you about it.
     Thanks in advance!
