Re: SCSI emulation in FreeBSD
Thomas, what I find very interesting is that it still works regardless of the commands that ATAPI don't understand, I know this is abit off topic, but would any hardware expert mind explaining? :) Will On Sun, 14 Jul 2002, Thomas Quinot wrote: > Le 2002-07-14, Willie Viljoen écrivait : > > > Just to follow up, I went back to -STABLE after discovering I don't need > > -current to do this (*slight sigh of reliefe*) > > Yep, I do most ATAPI/CAM develoment on -STABLE machines. > > > Thomas, ever consider asking for it to be committed into FreeBSD proper, > > atleast maybe into -current? > > This is being considered, but I am not the one who can make the decision > on this issue.

Re: SCSI emulation in FreeBSD
Just to follow up, I went back to -STABLE after discovering I don't need -current to do this (*slight sigh of reliefe*) Thanks Jan and Thomas, it works perfectly with both my BTC 36x ATAPI CD-ROM and the HP CD-Writer+ 9110. Thomas, ever consider asking for it to be committed into FreeBSD proper, atleast maybe into -current? The code is really good IMHO. Those ILLEGAL_REQUEST warnings come from that ATA driver, and they shouldn't scare anybody, but for the really paranoid, I'm sure they could be eliminated by some extra options for the ata(4) driver to allow us to silence error output (Soren?) Anyway, thanks for the quick replies. Also, I see Thomas's address in the list of CCs, I unsubscribed from freebsd-current after getting it fixed, so I missed what ever message he was involved in (if there was one) and I'd love to read it, so I'd appreciate it if somebody could forward it to me :) Regards, Will On Sun, 14 Jul 2002, Andy Sparrow wrote: > > > > > Anybody have any idea what I need and where I can find it? > > > > http://www.cuivre.fr.eu.org/~thomas/atapicam/ > > Just as a datapoint, I recently applied the ATAPI/CAM patches to a -STABLE > from July 10th). > > They applied flawlessly, compile was clean. > > My newly-acquired TEAC DW-28E CDR/CDRW/DVD drive now works perfectly with the > SCSI cdrecord from ports. > > And thanks to 'atacontrol', I can even hot-swap IDE devices in and out of the > laptop modular bay. > > This OS rocks!!

SCSI emulation in FreeBSD
Hi, I was scratching around the geocrawler archives yesterday, looking for information on using SCSI emulation in FBSD. I found some, but was dumb enough (yet again) not to bookmark it. I've synced my source with -CURRENT, and looked through all the options I could find, even a home-made LINT, still nothing. I read about a patch in the old message I found. Am I simply not seeing the options I want, or do I need to patch my kernel for this to work? The reason I want this is that I have an HP 9110 CD-RW drive. It refuses to work properly with the ATA drivers, and I refuse to reboot to Windows every time I just want to burn a CD. Anybody have any idea what I need and where I can find it?
