Help Sun Blade 1000

[Scott Einuis]

Hi People,
 
I've been using FreeSBD for years on x386 machines, and just yesterday
someone gave me a Sun Blade (Ultra-Sparc III) machine with an external SCSI
CD-ROM.  It has Solaris 8 pre-installed.
 
My questions are..
 
Should I keep Solaris 8 or install FreeBSD?
 
And 
 
Since I tried to install FreeBSD already and failed, how do I get the Sun
Machine to boot from the CD I created for SPARC boot only?
 
I tried using the eeprom command and changing the boot device to "cdrom" and
and I also tried the init 0 thing however when I probe-scsi nothing comes
up.
 
Any help would be appreciated.
 
Thanks
