Hi Suse users,

Greetings from me! I am a new SLES user.

I find there are 3 ISOs for SLES 12 SP1:

SLE-12-SP1-Server-DVD-x86_64-Beta2-DVD1.iso
SLE-12-SP1-Server-DVD-x86_64-Beta2-DVD2.iso
SLE-12-SP1-Server-DVD-x86_64-Beta2-DVD3.iso

From this link, I know the 1st ISO is for binary package,
and the 2nd for source package. But what is the role of the 3rd ISO?

Thanks in advance!

Best Regards
Nan Xiao
