Hi!
I'm trying to revive the sun4/110 i was gifted by a friend of mine...

My setup is: 
Sun4/110 mod.501/1512 - 20MB ram and no FPU - in a Sun3/60 box
Sun type-3 keyboard and mouse
Sun shoebox (actually containing a cdrom reader and a tape)
P4 3/60 cgfour color framebuffer (actually seems dead)
19'' Sun Hitachi Color monitor mod.365/1006 (seems working, but shows just a
light flashing green grid when the workstation is on).

After some black magic experiments (i hadn't configured rpc.bootparamd before,
and had no manual with me on holidays), i (almost) succeded in netbooting NetBSD
1.4 from my linux box.
Both kernels i have found in the installation directory panic during boot
(according to my nfsd, just after having opened and read two 8KB chunck of init)
in this way (this log is from netbsd.GENERIC.gz):

EEPROM boot device...sd(0,0,0) 

Does anybody know why? Does my sun miss a device the generic kernel is looking
for?
And, BTW, does anybody know why my framebuffer displays almost nothing (just the
flashing grid i said before), even when i set it on the NVRAM as the primary
console (addr.0x1f = 0x12) ? 
PN: the diags find no p4 device and no screen, but the original proms have been
lost (and replaced with version 1.8) and i don't know if this revision is full
compatible w/this board version.

Thank you in advance
Orazio Sottile
