Don't know if you've fixed this already, I don't know about configuring for CDRW as scsi emulation or whatever, but were you specifying iso9660 filesystem type when attempting to mount, ie. mount -t iso9660 /dev/(?) /mnt/cdrom man mount for syntax

Tried that, got (as 'me') "mount: only root can mount /dev/cdrom on /mnt/cdrom" and, as su root, I got: "mount: wrong fs type, bad option, bad superblock on /dev/cdrom, or too many mounted filesystems (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?)" > On another matter, someone else asked you to check permissions.

I remember now, and I'd say you're exactly right! Is this going to happen *every* time I upgrade? 8( > Since I use neither Red Hat > nor kudzu, I can't tell you in detail how to restore ide-scsi emulation, > but the outline is -- > > 1.

Yes, it is 0,0,0 I'm going to search back through my files and try and find the instructions I used when first installing the CD-writer. Unfortunately the original is on a cd-rom which I can't read at the moment.... :) As a related question, is there anywhere on the Internet a page that explains (in simple language) what the boot-up sequence of Linux is (and XFree86 for that matter) and what files get read in what order? Man pages are always much too detailed and limited in scope to be easy to follow. cr - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
