The chipset is an Intel 8x0 something. Unfortunately, there is a heatsink semi-permanently installed over everything. Is there a /proc pseudofile that will give me good identifying chipset info to report here? If there is a FAQ for this, we should post a message about it once in a while. Nothing here indicates chipset: http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html The CPU is an Intel Celeron CPU 2.00GHz running at 1495.772 MHz, 128MB cache. sdw Matti Aarnio wrote: >On Wed, Aug 10, 2005 at 08:32:45PM -0400, Stephen D.
