I used the CD I burned for disk 1 and the file size is not the same as the iso. -rw-r--r-- 1 root root 675309568 Oct 8 13:22 disk.out -rw-rw-r-- 1 jweber jweber 675315712 Oct 6 06:21 psyche-i386-disc1.iso When readcd asked me for the beginning and ending sectors, I accepted 0 for the start and subtracted 2 from the suggested ending sector. So this was to verify that my CD was OK except for the extra sectors (if I'd done it correctly)? No need to waste more time with me on this. My new DAO capable burner seems to have answered my questions. The CDROM I was installing from was also having problems, adding to my confusion. > > Maybe a related question: Is there a way to list and extract selected > > files (like rpm packages) from an iso image residing on a hard drive > > without burning to a CD? > > # mount image.iso /mnt/somewhere -o loop,ro > Thanks you very much for this tip! -- John S.
