It mounts OK on a Debian Linux 2.0.29 box. Other CDs mount on FBSD 2.2.2 OK. I have built the kernel only once. The CD ROM setup info from dmesg is: mcd0: type Mitsumi LU006S, version info: M 15 mcd0 at 0x634-0x637 irq 15 on isa Interestingly I cannot redirect the output from the command. Not with "tee". Not with 2>1&>filename. But, perhaps I should not be able to redirect? The above listings were obtained by cut & paste. Would it be helpful for me to email a dd output from the start of the CD? I could use my Debian box to get this. However, I am unfamiliar with CD filestructures and do not know how much to include. I have checked PRs: kern/4735, kern/750, bin/4564. The latest file in /usr/src/sys/isofs/cd9660 is iso.h dated May 7, 1997; filesize 10624 bytes. /lkm/cd9660_mod.o is dated May 20, 1997 If I can help in any way, please email. Best Regards, JohnT >How-To-Repeat: Any invocation of mount_cd9660 or mount -t cd9660 produces the same result. Attempting "mount -o -s=0 -t cd9660 /dev/mcd0a /cdrom" results in "cd9660: illegal option -s". Attempting to mount /dev/mcd0c, the raw device, produces the same results. >Fix: None. :( >Audit-Trail: >Unformatted:
