IIRC, a discontig memory implementation is needed for the I2 to use more than 256 MB, due to the memory layout on this machine (with aliased memory etc -- see the R3000 MC spec). I kind of lost track of this issue recently, so I may have forgotten some details and got part of the above totally wrong :) JB. -- Julien BLACHE <http://www.jblache.org> <jb@xxxxxxxxxxx> GPG KeyID 0xF5D65169
