Actually, it wasn't on that page as far as I could see, but I found it anyway. Also, in your original post, you neglected to include _all_ of the dmesg output from your system. You included the part where it said "ntoskrnl dummy called," which indicates the driver tried to call an unimplimented function, but you cleverly elided the part that where the PE loader said what those functions were. It would have been easier to spot were it not for all the other verbose mode output. Anyway. It turns out the two functions that were missing were trivial to implement (Sam supplied a patch to add them). Go back to the Acer site and get that driver again, and make sure to grab the latest version of subr_ntoskrnl.c from sys/compat/ndis. It should work this time. I'm running it with WPA mode on my Broadcom wireless PCI card in my dual Opteron system at home right now. Note: you will still see the "fpudna in kernel mode!" messages emitted by the kernel periodically. It appears the Broadcom driver binary is using some floating point instructions in the kernel. I'm not exactly sure what those instructions are because I don't have an amd64 PE disassembler utility. For the time being, the message seems harmless. The driver seems to work anyway: [/u/wpaul]:opteron.moo.com{6}% dmesg | tail -10 ndis0: <Broadcom 802.11g Network Adapter> mem 0xe0210000-0xe0211fff irq 31 at device 1.0 on pci3 ndis0: NDIS API version: 5.1 fpudna in kernel mode! ndis0: Ethernet address: 00:30:bd:f5:ea:26 fpudna in kernel mode! fpudna in kernel mode! fpudna in kernel mode! fpudna in kernel mode! fpudna in kernel mode! ndis0: link state changed to UP [/u/wpaul]:opteron.moo.com{7}% uname -srm FreeBSD 6.0-RELEASE amd64 [/u/wpaul]:opteron.moo.com{8}% ifconfig ndis0 ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::230:bdff:fef5:ea26%ndis0 prefixlen 64 scopeid 0x3 inet 10.0.0.9 netmask 0xffffff00 broadcast 10.0.0.255 ether 00:30:bd:f5:ea:26 media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps) status: associated ssid "test network" channel 6 bssid 00:02:6f:20:b3:e0 authmode OPEN privacy OFF txpowmax 100 protmode CTS Note also that the NIC really is running in WPA mode. Apparently, when you query OID_802_11_AUTHENTICATION_MODE with the Broadcom driver, it always returns 0 (open). > Currently I'm using a different atheros (Netgear "dual 108" card; fbsd doesn't > see the independent transceivers but it does work in a, b, and g mode.)
