Re: [gentoo-user] Re: /dev/cdrom has gone!
thanks to all... i finally get the cdrom work, not perfectly though, i change the BIOS setting that use S-ATA only instead and keep P-ATA enabled, which makes cdrom the primary 1st, the sata drive recognized as primary third. (i hate such layout !! i prefer the hard disk to be the primary first and recognized as hda). at last, the sata drive was recognized as sda, so that's the whole story, now i'm wondering what on earth are the changes made with those BIOS settings, and how it affect the kernel? (because whatever i configure, the M$ Windows just works perfectly). i would not think the problem solved already, i'll take a look at this later. thanks again. daniel On Sat, Sep 03, 2005 at 02:35:51PM -0400, Greg Yasko wrote: On Sat, 03 Sep 2005 18:19:37 +0800, danielhf wrote: i upgrade my system to use udev instead of previously known devfs, and leave the devfs option blank while configure the kernel, but recently, i found i could not mount my cdrom, there is no such device at all! the /dev/cdrom and the like has gone! any ideas please, thanks a lot. - daniel I had the same problem several months ago when I upgraded to the 2.6 kernel and udev.

I run ~x86 systems, always kept current, so I expect a few minor hiccups, even though I'm extremely careful with etc-update. There seems to be some weird stuff going on with udev, at least on my system, but after a lot of reading on the formum, and trying many things, I tried changing my fstab line /dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,rw,user 0 0 to this. /dev/hdc/mnt/cdrom iso9660 noauto,rw,user 0 0 I think some rule in the new udev changed, and it wasn't creating cdroms and cdrom0 anymore- only /dev/hdc. I looked in /dev, and sure enough, the cdrom and cdrw links point to the hdc block device. Anyway, whatever it was, changing the fstab line now lets me mount cdroms normally, as before.

Steve -- Steve EvansE-mail: mailto:[EMAIL PROTECTED] WEB:http://www.gorbag.com Registered Linux user #217906: http://counter.li.org Public Encryption Key: http://www.gorbag.com/public-key.html Steve, What you say makes perfect sense, but I'm still not sure I have an understanding of what has changed. I always compile my own kernels from vanilla, and patches, so I haven't used gentoo-sources in at least 2 years. My current kernel is 2.6.13-gvivid (based on 2.6.13 final), which works great, and is where I first noticed this cdrom problem. I did notice that devfs had finally been removed. However, when I boot with other previous kernels (2.6.12.x- vivid and nitro, and 2.6.12.3 vanilla), the problem remains. This leads me to believe that somehow it's the newest udev version causing and some kind of compatibility issue with recent kernels. I haven't investigated this much, but it didn't happen with the previous udev version. Anyway, for now I'm content with the fstab hdc edit resolution, and happy to be rid of devfs..

[gentoo-user] Re: /dev/cdrom has gone!
P-ATA only | S-ATA only | P-ATA S-ATA etc and some others. i use a Native Mode, so that my disk can be recognized as /dev/hdaXX instead of /dev/sdaXX. and P-ATA only but with S-ATA enabled. What's wrong about /dev/sdaX ? That's exactly how it should be. So disable that strange native-mode and instead enable the SATA driver in the SCSCI-driver section of your kernel. signature.asc Description: OpenPGP digital signature

Re: [gentoo-user] Re: /dev/cdrom has gone!
i did read that document, to find the doc is trivial. what i got is just similar. the udev just create the device files which were detected by kernel, and handle the operations like add or remove dynamically. i tried this feature with my usb devices already, i really like the way udev works. i could not found any info from the output of dmesg, so i think perhaps there is a problem on detecting the device, but not the problem of udev. thanks daniel On Sat, Sep 03, 2005 at 08:40:20AM -0500, John Jolet wrote: On Saturday 03 September 2005 08:20, Matt Randolph wrote: Alex Korshunov wrote: [EMAIL PROTECTED] wrote: On Sat, Sep 03, 2005 at 08:32:56PM +0800, [EMAIL PROTECTED] wrote: no error on reboot now, but i will try to switch to windows to see if the cdrom works well All my cdroms in /dev/cdroms/cdrom.
