FreeBSD on the Xybernaut IV TC

FreeBSD runs just fine on the Xybernaut IV TC Mobile Assistant. Here are some hints on how to make it work on your system, relative to FreeBSD 4.6.

Installation

I install FreeBSD via FTP, booting from a standard USB floppy. The MA IV TC has a number of onboard peripheral components which don't have external connectors. Specifically, it has a keyboard controller, but no PS/2 connector. Therefore, you must make sure to disable the atkbd0 device via the kernel configuration tool before proceeding with the install.

The snd kernel module supports the on-board ESS 1869 sound chip.

Unfortunately, the APM BIOS (at least the one that shipped with my MA IV TC) is buggy and causes a kernel panic. Hence, you must disable it.

XFree86

XFree86 4.2.0 supports the C&T VGA chipset. (Earlier versions of XFree86 4 didn't work.) Use

XFree86 -configure

It's also possible to get the Gunze touch panel to work via an modified version of Alessandro Rubini's Gunzets package. Here is the tarball.
