Solaris 8 install problems on Ultra 10

I have an Ultra 10 and I am trying to install Solaris 8 on it. I have actuall real Solaris 8 CDs. I put it in the cdrom in, hit stop-a and type 'boot cdrom'. The system resets.

When it boots it I get:

Can't open /pci...etc

Can't read disk label

Can't open disk label package

Can't open boot device

Any ideas?
