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.
