It will not work - the current OS limit is 1G for shure. > Although the hardware allows you to install up to 1.5Gbyte of memory, > FreeBSD is limited to 1Gbyte because the DMA code does not correctly > handle memory above 1Gbyte.

So FreeBSD currently limits Miatas more then hardware. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
