No unpacking. Its not a bad idead to use md5 to make sure the big file isn't broken. If you are already running FreeBSD and have an ATAPI/IDE CD-R then something like this will create the cd: # burncd -f /dev/acd0c data 4.2-install.iso fixate Probably want to read the burncd manpage as I am not sure what happens when you fail to specify -s speed. I've only burned one, and at 12x with the "-s 12" option, and it worked perfectly the first time. And yes, I saw 1.79MB/sec on the device using "systat -v" during the burn. If you have a scsi CD-R then you need the cdrecord port. The command line is different but the idea is the same. If you have Windows or Mac then you need the appropriate utilities for thost machines. As others have mentioned if you have a FreeBSD machine, and if it has the vn device compiled in the kernel (GENERIC as of recently) the you can: # vnconfig vn0c 4.2-install.iso # mount -t cd9669 /dev/vn0c /mnt And play with the contents that way. For example I wasn't sure my new CD-RW and $0.13/disc media really worked. So I mounted the image, and the new CD-R, and let "diff -r --brief /mnt /cdrom" crunch for 20 minutes or so until I realized its probably walking thru all of packages/All and packages/*/* because it doesn't know about hard links and that those files are the same and about 3/4 of the disc. Did find the CHECKSUM.TXT file listed a thing or two that wasn't there, and at least one thing that was there. Jordan said on the second roll of 4.2.0-RELEASE that he was adding something. Apparently in the haste CHECKSUM.TXT didn't get updated. Then to clean up what you just did first unmount the filesystem, then unconfigure the vnode to detach the file you attached to it earlier: # umount /mnt # vnconfig -u vn0c -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
