I get to see bad CDROM problems all the time. Mostly when vendors buy crap cables to try to save $0.02/each, but there are chipsets and drives with known DMA issues as well. > Normally, even if you try to enable DMA and your device doesn't support it, > it simply don't be able to make the change, and that's it. The problem IIRC > is with crappy hardware that is supposed to support DMA but doesn't work as > expected when it's enabled... maybe Chris could confirm this? ;-) Usually if you enable DMA on a CDROM that can't handle it gracefully you won't be able to read data off it relably, and that's about it. No end_of_the_world problems, and easily fixed. > I guess I'll settle for the /dev/dvd link change as described and putting > the DMA tip in the %description :-) My biggest beef with automatically setting /dev/dvd is that I always seem to have a CD-Burner and a DVD drive (or DVD burner) in the same box, and I usually have the DVD as the second drive /dev/cdrom1 in "kudzu-speak". I agree that the %description is the best place for the tip. Unless someone can come up with a way to probe CD/DVD drives to divulge their largest supported media size without loading ide-scsi or having that media currently in the drive. -- Chris Kloiber _______________________________________________ RPM-List mailing list http://lists.freshrpms.net/mailman/listinfo/rpm-list
