All major hardware in our laptop and notebook systems is supported in Linux. The EmperorLinux research staff modifies all the popular Linux distros in many specific ways to provide the best possible portable Linux distribution. These include a customized kernel (packed with driver patches and half the size of distribution kernels); a chip-specific X-server with hardware acceleration; full support for PCMCIA, USB, and FireWire devices; full support for 10/100/1000 (gigabit) ethernet and 802.11a/b/g/n wireless; pre-configured power management; modem; stereo sound; and more. (There is extensive detail on the following topics in the supplied owner's manual.) Detailed information about mobile wireless broadband (EVDO, HSDPA, etc) and the Intel Core Duo is also available.
All this is done completely with GNU-GPL software. At EmperorLinux, you don't pay extra for commercial X-servers and sound support, because we only use laptops for which the hardware is known to be supported by truly free software.
