I have done the patches to vanilla 2.2.7 src's, the patch fail in three places, the big one is mt.c, but repair by hand is done, the Makefile where camcontrol is listed, repaired by hand as well, (please note that reference to lfs has to be removed, it looks like it is not in 2.2.7), and last the release/Makefile is not updated as well, but this time the version used was somewhat too different to accept the patch, I pardon patch for this one. (For the preceding one I don't understand why it was rejected.)
So I have a 2.2.7CAM running happily on my P2BS, using currently only narrow SE devices.
Some questions : the disques (a jaz and a zip) are called da0 and da1, when they are dedicated ufs disks, no ms-dos partitions, the naming is ok : da0a .. da0f idem for da1 (there is 3 or 4 partitions on each) When they are regular FAT disks, then I dont understand why /dev/da0 is for the jaz and /dev/da1s4 for the zip ? Why not da0s1 for the jaz ? If I had scsi HD, they will be da? right ? I have no sd??? devices in the /dev. (at some point there was, but I erase them, probably to reMAKEDEV all)
On the aic7890 there is a lvd, a UW, and a U connector (I use only the U), if I have, as it is now, devices on the narrow SE connector, will the disks on the lvd channel work in lvd full speed fashion, without limitations from the lowly SE devices ? I did not find a clear answer in the Adaptec blurb. Same question about the UW connector.
Or, in the event of having fast lvd or UW disks, should I use a separate controler, I can find a Tekram 390F or 390U somewhere, that I will use dedicated to SE devices. Comments ?
Now a bad part. I have that 2.2.7CAM running on wd0s2, and I want to build a backup system on the zip. I cannot use the 2.2.7, it would not access the zip, aic7890 not supported there, I did it with some success with the 3.0CAM-SNAP, direct installation on the zip, but as it is something I will need in the future, I want to know how to make and install a system on a small disk, from an other one. 2 ways I can think of, make a release out of the 2.2.7CAM I run, but reading some the ink on the paper told me I need the complete CVS to do that ! I dont have a complete CVS at hand, that's for sure. I don't like that idea much... The other way, I think it is possible in Linux, is to create the / /var /usr trees on the target disk, transfert the needed files, and make a custom kernel, with all proper boot devices etc. configured, and simply copy it on the target disk. Any infos, advices ? (All this because I have an (yet) release unsupported device... but it is giving me the opportunity to learn a lot about FreeBSD)
Some other subject : On the SCSI I have a CD reader, a Plextor PX6-CS, and a CD writer, a Plextor PX-R412. Can I copy CD's with those ? at full (4x) speed ? Raw (bit by bit) copy ? CD-Audio and Iso9660 ? The Plextor are not mentionned in any hardware list I read in FreeBSD library. Both run well in reading Data CD & Audio CD in FreeBSD/X11.
