I have CentOS4.1 up to date and I get on boot:
ipw2200: Detected Intel PRO/Wireless 2915ABG Network Connection
divert: allocating divert_blk for eth1
ipw2200: ipw-2.2-boot.fw load failed: Reason -2
ipw2200: Unable to load firmware: 0xFFFFFFFE
divert: freeing divert_blk for eth1
ipw2200: failed to register network device
ipw2200: probe of 0000:03:03.0 failed with error -5
My understanding from RedHat is that the current update
includes ipw2200 v1.0.4.
I have googled around, and cannot find a decent howto.
