I have a question (this might need to go to -hackers, but I thought I would try here).. I'm playing with the MD_ROOT_SIZE option a FreeBSD 5.0 config file. When I set the size to anything over 7000, I get a nice little isa_dmainit(2, 1024) failed message at startup (which results in a kernel panic with: panic: isa_dmastart: bad bounce buffer (since a dma buffer wasn't able to be allocated at bootup) My question is what is the maximum size MD_ROOT can be? I thought that if there was enough memory on the system, it shouldn't matter how big it is. =20 Is there any way to get rid of this? The system I am playing with is useable without a floppy drive, but it would be nice to be able to use one. (Yes, this is me playing with my WarBSD stuff. I thought the problem I was having was gone with -p16, but it turned out I was just tired and overlooked a setting-- MD_ROOT_SIZE being set to 7000). Thanks in advance. -Stacy
