Gee, I ask a seemingly simple question about connecting a very simple driver to the system and all of ZERO people chime in with help. The only thing anyone had to say involved something like "Read and update isa_compat.h" and I can take it from there! However, noone said that or anything else for that matter. It really upsets me because it seems that absolutely *no* documentation exists for how to connect a driver to FreeBSD 4.x. Documentation exists for 3.x and 5.x, but none for 4.x. This mailing list just seems useless to me. /Joe

PCI drivers are fairly easy to hook up, but ISA drivers still have a lot of black magic. I would suggest that you post to hackers@ before giving up. Scott

Probably more than 90% of the response involved snide and sarcastic remarks about how no one should ask questions on the stable list and ever expect to receive an answer to them. A very small percentage of respondents actually offered sympathy and some even offered good ideas. I want to thank those few people who actually responded with non-sarcastic and non-snide information for their help. I also want to tell anyone who felt compelled to send me a snide or sarcastic remark that I have safely placed your response in the appropriate folder.> This mailing list just seems useless to me.You know, all anyone ever had to do was to answer my original request with a simple message saying please ask again on -hackers. Or simply point me at the particular file which contains the linkage code for old-fashioned device drivers. No one did this until I sent out my message complaining about how hard I find it to work in the totally unhelpful environment. I personally have years of experience working around many different environments, and the most difficult part always involves trying to figure out someone else's undocumented code. I specifically did not want to go down the whole isa module route as that adds an incredible amount of seemingly irrelevant cruft to a very simple device driver. Anyway, I have nothing else to say on this matter. /Joe

stable tends to be more user oriented, and less developer oriented. I
read it less often than I do the other lists.
Maybe if you could send me your driver, I can point out the problems
in it. Since you didn't provide any code, it really is hard to guess
what might be going wrong. isa_compat.h almost certainly isn't the
answer, since that's only for drivers in a transition period from the
old APIs to the new ones.
