I won't comment on which is "better", but the FreeBSD driver is based on the NetBSD driver, and an *old* version at that. This would seem to indicate the FreeBSD driver has bugs that the NetBSD folks have since fixed, but I haven't used the FreeBSD 3c509 driver myself, and have very little experience with the NetBSD one [so YMMV]. The NCR driver, I believe, is common to both OS'es. As far as bounce buffers for the 3com, I don't think it does DMA, so you should find no need for bounce buffers regardless of memory. --rafal +------------------------------------------------+-------------------------+ |"Blessed are the meek, for they shall inherit | Rafal Boni | | 15% of the earth, which is 100% more than they | r-boni@uiuc.edu | | have now..." -Cartoon caption in New Yorker | My opinions, not UIUC's | +------------------------------------------------+-------------------------+
