Yes and no. A non busdma driver must be aware of alpha to work. Otherwise a busdma driver is required only for large memory situations, which we curently don't support yet. > The box has currently 512MB of RAM, but will be stocked up to 1GB soon, > which according to docs is the limit with FreeBSD due to dma limitation. My impression was that Miatas are also limited to 1G by hardware? Does anyone know if Miatas can be fit with >1G? -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
