(Please wrap your lines) IIRC not, I have a DVD-RAM drive and it probes as cd(4), not as sd(4). And btw, IIRC our UFS/FFS implementation does still not cope well with sector sizes != 512 (which makes MO drive usage difficult too, as they *are* sd(4), but with 2048 byte sectors). Or has that, at least, been fixed in-between? IIRC, DVD-RAM has larger sectors, too, and *usually* one uses UDF2 there (our UDF support is 1.1, read-only, only). Kind regards, Hannah.

I wasn't asking if the device could be attached as sd, I meant.. could DVD-RAM drives be used as if they're like an ordinary drive that attached to sd(4). That might not be what you asked; but it still could be the answer to your question. I've been on this list long enough to know that if an answer does not right away make sense to me; then in some way I don't get it and extra reading is warranted. Maybe that's happened here. OpenBSD names devices based on driver used. I haven't looked at code (I wouldn't understand it anyway); but I would not expect the cd(4) device driver to support random writes; whereas the sd(4) driver would. I suspect that if your DVD-RAM device *were* detected as sd; then it *might* behave as an sd device. Then again; I might not even have a clue...

I can read DVD-RAM disks written in my video recorder or in winXP on a drive in an OpenBSD4.2 box. mount_udf mounts the drive ro, so no writing is possible. I used to want support for writing DVD-RAM because the type 2 cartridge disks are rated at 100,000 write cycles and are truly random access. Trouble is that cartridge drives are now very hard to get (I have only 2, one in a Panasonic DVR and one in a winbox) so I am popping the platters out to use in regular drives. BD-RE support would suit me fine right now but the media are too expensive so far and the drives ain't cheap either.

Redirected from ports@ to [EMAIL PROTECTED] An explanation of what lead you to post it to ports@ would be interesting, second one of those in a couple days, starting to sound like something is unclear somewhere. [EMAIL PROTECTED] wrote: Hey All, I'm trying to install OpenBSD 4.2 and have created an ISO image using ISORecorder for XP. The creation of the image on the CD completed with no errors. When I boot from the CD to install...the script begins and I get some white text on blue background...but then the install stops at the following message: cd0 at scsibus0 targ 1 lun 0: HL-DT_ST, DVDRAM GSA-E50L, NE01 SCSI0 5/cdrom removalable any ideas would be greatly appreciated. Thanks in advance. You have given us almost nothing to go on. however... I notice you have a DVDRAM there. I've only had one of those, and I pulled it out of the machine it was in because it seemed to be defective. I could be wrong..it may be that only two people have ever tried to install OpenBSD on a machine with a DVDRAM drive into OpenBSD, you and me. Or maybe you and I are the only owners of defective DVDRAM drives. SO, first thing I'd try is to pull the DVDRAM drive out and use a CD or DVD drive, see if that works better. If so, let us know, I'll look into my defective DVDRAM drive more. If not, tell us SOMETHING about your computer, or (much) better yet, just put a serial console on it and snag the boot output and let us look. Or type out a lot more of what you see on the screen. Put the digicam down, I'm not looking. Nick.

Re: install42.iso hangs....any ideas?
Sorry for hijacking this thread, but it brings up an interesting question.. How well does OpenBSD support DVD-RAM drives? does the cd(4) driver support read/write operations? - i.e: Would it be possible to use it as a normal block device? Again, sorry for hijacking.. unfortunately, I'm not sure why your system is bailing out at that point, consider enabling verbose in UKC. (boot -c) ..And yet another off-topic question, What about Mount Rainier (packet writing) support for CD-RW drives? that would be so awesome! :D -Nix Fan.
