I'm sure there is info on the web site, and in HARDWARE.TXT in the distributions (see section 3 - LINT - other configurations). Supported cards are: Digi, Cyclades, Boca, Stallion, AST. RocketPort drivers have been committed to -current recently. I have used Cyclades, AST and a Boca-8 type called the TC-800. FreeBSD does not make use of the special port register of the TC-800, and I found that when running mpd (multilink ppp daemon) on a TC-800 the second channel was starved of interrupt servicing, presumably because mpd synchronises the data it transmits on each channel, and channel 1 was always serviced by the shared interrupt, and channel 2 not. TC-800 is fine for light use customers. AST/4 clones I have work fine with mpd under high load. Cyclades is pretty good; I use ISA version myself; the ISA driver is more reliable than the PCI, I have heard. Danny
