Tru64 - can not read CD

[Sinai <gsinai gol com>]

Hi,
I got hold of Tru64 for $99. I bought it just to install their
shared libraries - mostly I need their libpthreads.so. I had other
osf libraries already. 

I could read all the CDs EXCEPT the first one with the Java logo. Am I
supposed to read it as iso9660 on Linux.

mount: wrong fs type, bad option, bad superblock on /dev/hda,
       or too many mounted file systems

All other CDs are ok.

Did any of you have the same problem? Am I supposed to read this CD? 

Thanks
