Nop, There is nothing wrong with your hardware.  It is just the EEPROM 
setting.  If at the boot prom you type q; it will give you your prom 
settings.  Read the sun NVROM faq and SUN EEPROM faq or refer to sun 3
eeprom manual.  just from off the top of my head I wound say 12 needs to be
reset.  If you don't find the documentation you need get back to me and I 
wil dig it up for you.  To get out of erpom setting type q again.
