sun Ultra 5 (no screen at boot)

[Xavier Oswald <x.oswald@free.fr>]

Hi,

I just get some Sun ultra 5.

When I turn on the computer, everything seems to work well but nothing
appears at screen and it stays black.

I tried to change the keyboard, the computer, and my monitor works well
with my intel32 computer. (I use a VGA monitor)

More infos about this sun machine :

So i don't understand why it don't work, any idea ?

Thanks !!!
