Since so many people gave me on -mobile and -questions gave me so much help, I'd like to *TRY* to continue working on adding support for the Broadcom 4401-B0 to FreeBSD. Here's where I came from: None of my CardBus, NIC, WiFi, etc devices were getting register memory: http://phpbootcamp.com/articles/inspiron700m/dmesg_verbose.txt All hardware worked fine under Windows. Well, as fine as anything works under Windows. :-) Here's where I am: I can use "allow_unsupported_io_range" and all my devices get identified and assigned what look like valid memory ranges: http://www.phpbootcamp.com/articles/inspiron700m/hw.pci.allow_unsupported_io_range/dmesg.txt Attempting to configure the NIC using ifconfig or the sysinstall GUI locks up the machine completely. So, which of the following most likely describes my current status: A) The unsupported_io_range is fine, but the driver source needs hacking B) I really haven't solved the device register memory issues -- they just *SEEM* to be okay. If it's A) I can start mucking with C code and hopefully not damage my hard drive too much in the process... If it's B) I'm still at a complete loss how to compute valid io_range... Use the Windows numbers, since they work? Use the Linux numbers, since they work? Some kind of tool/monitor to compute a base offset? If it's A) I can also start playing with the CardBus and WiFi with some hope of it working. If it's B) there's not much point in my buying a PCM/CIA WiFi card, now is there, as the Cardbus io_range ain't gonna be any good either, is it?... -- Like Music? http://l-i-e.com/artists.htm
