The ISO images I have don't appear to include a boot image - the 2 CD images also are numbered 3 & 4 in files held on them but other than that anomally appear to be the 1st 2 CDs of RH.
Because they aren't boot CDs, can you point to process to boot them ? (am assuming I can either download a boot diskette or use one off 7.1 - couldn't find one on the 2 CDs)
