[NTLUG:Discuss] 2 Questions about creating CD's from iso images.

[Jim Wildman]

For an install, you will only need the first 3 disks.  Run md5sum
against each of the .iso files and compare the output to the MD5SUM's
you downloaded for each.  It will save you time if your download
burped.  

I agree with the cdrecord command recommendations.  I've got plenty
of RAM, so my cdrecord command is..

cdrecord -v speed=8 dev=0,0,0 fs=16m <filename.iso>

Never coasterized anything yet.
