well i don't know what is with people lately putting their questions in this fourm, but don't.
this is the member intro, not a member intro with their first new problem fourm ...
you should have put this question in something like :
Linux - Software
Linux - Newbie
Linux - General
any of the above would have been sufficient ...
anyways as of the problem:
Pshyche 8.0 Disk 2 means insert your Redhat 8.0 Disk 2 ...
pshyche is the name given to redhat 8
just like shrike is the name for redhat 9
