I have Volumio installed and working on a USB flash drive pluggged into a Dell laptop.
Intel Core 2 Duo
Biggest problem was getting Volumio to access the internet through my laptop’s wireless card. From a terminal I entered lspci -vnn -d 14e4: The results are below.
0c:00.0 Network controller : Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
Subsystem: Dell Wireless 1395 WLAN Mini-Card [1028:000b]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at fe8fc000 (64-bit, non-prefetchable) [size=16K]
Kernel driver in use: b43-pci-bridge
The two files I downloaded are b43-fwcutter_018-2_i386.deb and broadcom-wl-5.100.138.tar.bz2. Put them in a folder named offline_firmware-b43-installer. From my working Linux distro on my HDD put that folder into /volumio_data/dyn/home in Volumio on the flash drive. Then booted into Volumio and brought up a command line. Then the following.
cd into offline_firmware-b43-installer
sudo dpkg -i b43-fwcutter_018-2_i386.deb
tar xvjf broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware wl_apsta.o
sudo chmod 755 /lib/firmware/b43
Reboot Volumio. Volumio should start wireless internet. I went into Network on the Volumio menu and there was a list of available networks. Chose mine, entered my password and was connected. I’m not an expert on this, obviously, so I hope my instructions make sense.
