This happens to be also the case with my Tyan Thunder K8W motherboard. It also seems to a rather important issue when running a Linux distribution based on kernel 2.6.x on such a Tyan Opteron board. Tyan switching off the Parallel Port is even also reported at the public forum at amd.com : http://forums.amd.com/lofiversion/index.php/t43260.html Recently however when updating to the newest BIOS release for Tyan Opteron boards the parallel port seems to be switched on again inside the factory default settings. Exactly as we have seen with your Tyan Tomcat single Opteron CPU board. The fact however that _all_ the various Linux distributions I have tested so far, both 32bit and 64bit AMD64, seem to have severe problems with the parallel port implementation of Tyan Opteron based boards, is so far _nowhere_ mentioned. All problems of Tyan Opteron based machines silently locking up during installation and/or during normal operation of running Linux, both 32bit and 64bit, without any display of kernel panic of any other logging method, seem to be solved when switching off the Parallel Port inside its BIOS. So here my official complaint to Tyan and the Linux kernel developers to either make public notice of these problems, or preferably create a solution/workaround for this problem either in software or hardware or maybe inside a BIOS update.
