If you want a NetBSD-like OS that runs on i386 and Atari, you might try OpenBSD. They have bounce buffers on i386. However, OpenBSD has only a "-current"-like state. You need some experience to install and use OpenBSD, more than to use a NetBSD release (not to speak of FreeBSD). I remember someone has bounce buffer patches for NetBSD-1.1. If you need them, mail me, I'll try to find them. >Having said that, when will bounce-buffer support be integrated in >NetBSD-current? Some of NetBSD's developers want a bounce-buffer solution that is not specific to one spefic kind of device or one kind of machine. For example, the DEC Alpha machines have ISA bus, but to use ISA cards with DMA you *always* have to use bounce buffers, even with 16 MB of RAM. The implementation should share as much code as possible for different tasks and abstracts the details so that adding additional usage for bounce buffers is less work. This is not a comment on the quality of the FreeBSD and OpenBSD bounce buffer solutions, I don't know anything about them. And I don't speak for any development team, if you want qualfied comments about the state of NetBSD's bounce buffers, see the mailing list archives of current-users and port-i386 on their WWW server. The issue has been discussed several times over the last months. I can't resist, sorry, but let me say that you bought a machine and a SCSI controller that cannot use more than 16 MB of RAM. Now you put 24 MB of RAM in it and want your OS to fix it. Mumble...
