Should I go ahead with the changes for -stable? > Without them, FreeBSD may not work properly with 512MB of main memory. Yes, I think this change should be made at this time. Why: Until now you could not find a MB that supported >256MB, now with the P6 boards shipping as well as Triton-II on it's way (I can get a Triton-II Intel board, but am waiting on ASUS's) it is possible to get to the 512MB mark (and beyond with P6). And a little side note... I would like a chance to quote you a price on that 256MB of memory, I take it that these are 64MB 72 pin parity simms. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
