I want to believe you :) (Btw, I haven't any Adaptec controller to perform the comparison:) ) > However, is there a reason why the driver is different from the one > in the base system? i.e. Why do you keep two copies of the driver? :) If fact there are 3 copies: :) - sym-1.6.x series in the base systems. Is the same (modulo a couple=20 of diffs due to kernel changes and latest commit not yet MFCed) in RELENG4 and TRUNK - sym-1.7.x in which I did dangerous changes I planned for sym-2 This driver series is withdrawn now that sym-2 exists. - sym-2 (current is sym-2.1.6) For now sym-2 is still beta status. It may well be at least as good than=20 latest sym-1.6.x for FreeBSD, but it is still beta for Linux. If I commit it to the FreeBSD repository, then it will go to production systems and large changes will get critical to apply to this sym-2. Or, in the _worst_ case, I will have to fork it, and as a result I will have=20 StillAnotherDifferentSymbiosDriverToMaintain.:) Btw, I planned to have sym-2 ok before 2001, and as we can see I am late for sym-2. Software development almost always takes more time than expected and sym-2 does fall in this category. :) For this reason, I have decided to maintain sym-1.6.x until sym-2 will be ready. If you follow the committers list, you will see that I am currently committings minimal changes to stock sym driver in order to maintain it at the same level as sym-2. MFCs happen 1 week later since they are not critical fixes. In my opinion, users will not see any difference between stock sym drivers and sym-2.1.6 under FreeBSD-4.x and 5.x. I just recommend sym-2.1.6 for RELENG3 for the following simple reasons: - sym driver in RELENG3 is an old version. - I have checked that sym-2.1.x does compile and work with RELENG3. - I am not sure that moving RELENG4 sym driver source to RELENG3 still compiles.
