* On Fedora Core 8...
* I just wanted to get on here and report my story. I was VERY
HAPPY to find Jesus posting in the archives. He may have had a problem with
Broadcom chipset, but his posting sure helped me solve mine. I was about to pull
hair out when getting "Sorry, the input file is either wrong or not supported by
the b43-fwcutter. This file has an unknown MD5sum <whatever it was...>." I
also tried with a Windows .sys file, and who knows what else. I was about to
think I needed another version of the CUTTER program, or to figure out what
really driver file I needed that has the right firmware.
I had just picked up a Linksys WPC54GSv2 wireless PC card in
exchange for the Belkin Mimo card which gave nothing but trouble. I tried what I
thought was the correct Broadcom download from downloads.openwrt.org but the one
that he mentioned was the MAGIC ONE! http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
I extracted that and ran "b43-fwcutter -w /lib/firmware/
broadcom-wl-4.80.53.0/kmod/wl_apsta.o" as he mentioned. He seemed to have a
problem where he was saying that none of those extracetd files going to
"/lib/firmware" were the correct thing that was needed in his situation. But it
sure was GOLDEN for me. I was seeing in the /var/log/messages that it was
wanting "b43/ucode5.fw" (also confusing in the text it says you need version 4,
why the "ucode5.fw" THAT's CONFUSING, a little bit...). Anyway it must be that
Fedora Core 8 with this WPC54GSv2 card surely needed "ucode" something or other
along the lines of 4 or 5? And the card came right on.
So thanks Jesus Jr M Salvo for unknowingly
saving the world. Or at least my little old Sony Vaio Laptop's corner of the
world!!!!

Compaq Presario V6107AU running Fedora 7 with a
Broadcom wireless chipset.
Kernel: 2.6.22.7-85.fc7 x86_64 /var/log/messages shows this:
Sep 23 19:31:34 c211-30-78-254
firmware_helper[4763]: Loading of

for
/lib/firmware/bcm43xx_microcode5.fw It tells me to get the firmware from http://linuxwireless.org/en/users/Drivers/b43#devicefirmware ... which then says to download http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2 ... which when extracted has a wl_apsta.o ... which when extracted with b43-fwcutter ( as per instructions in the link above ) does NOT produce a file called /lib/firmware/bcm43xx_microcode5.fw, as shown below: # b43-fwcutter -w /lib/firmware/ broadcom-wl-4.80.53.0/kmod/wl_apsta.o This file is recognised as: filename : wl_apsta.o version : 351.126 MD5 : 9207bc565c2fc9fa1591f6c7911d3fc0 Extracting b43/ucode4.fw Extracting b43/ucode5.fw Extracting b43/ucode11.fw Extracting b43/ucode13.fw Extracting b43/pcm4.fw Extracting b43/pcm5.fw Extracting b43/b0g0initvals4.fw Extracting b43/b0g0bsinitvals4.fw Extracting b43/a0g0initvals4.fw Extracting b43/a0g0bsinitvals4.fw Extracting b43/b0g0initvals5.fw Extracting b43/b0g0bsinitvals5.fw Extracting b43/a0g0initvals5.fw Extracting b43/a0g1initvals5.fw Extracting b43/a0g0bsinitvals5.fw Extracting b43/a0g1bsinitvals5.fw Extracting b43/lp0initvals13.fw Extracting b43/lp0bsinitvals13.fw Extracting b43/b0g0initvals13.fw Extracting b43/b0g0bsinitvals13.fw Extracting b43/a0g1initvals13.fw Extracting b43/a0g1bsinitvals13.fw So I am confused about the instructions from the website.
Instead, I downloaded the XP drivers from Compaq / HP and extracted the firmware files instead using bcm43xx-fwcutter ( instead of b43-fwcutter ) .... which produced the file that the b43 driver was looking for ( /lib/firmware/bcm43xx_microcode5.fw ) and other firmware files. So why was the b43 driver looking for a firmware file that cannot
be
produced by b43-fwcutter ( but produced by bcm43xx-fwcutter ) ? Does this mean I am using a v3 firmware ? ... but I though b43 driver is only for v4 firmware ? So I am confused as per above...
