Hi everybody !
The problem was solved thanks to an ideea given to me by David =
(Thanks David). I just modified the OBP variable boot-file from the =
from the
default empty field to "/platform/sun4u/kernel/unix" . Now works O.K. I
still think there is a problem in firmware, which was not solved by the
upgrade to the latest firmware level available. But since there is this
workaround available, I'm not too concerned about.


This is an old problem.=20

Look in the archives Jan thru May, and I think you'll find the =
permanent way
around the problem. I had that problem when I first took over this job, =
there is a patch which fixes it.=20

The short term (quick) fix is as you show:=20

boot: cannot open kernel/unix=20
Enter filename [kernel/unix]:           /platform/sun4u/kernel/unix =

Not a good solution with a critical machine!=20

Hi everybody !=20
I have a Netra 1405 (same motherboard as Ultra80 and Sun E420R). I boot =
sistem from the first internal disk (c0t0d0).=20
However, every time I try to boot or reboot it, the machine stops and =
"cannot open kernel/unix". I found a little trick, I press enter few =
then I press / and Enter once and then again I type kernel/unix and =
Enter twice and the machine boots.=20
I did not played with OBP variables and is the only one who do this. I =
thinking is an outdated firmware and I upgraded OBP to a version from =
2001 (before it was a firmware version from dec 1999). Nothing changed. =
machine is new and always did this.=20
I noticed is not a timing issue (for example I allowed plenty of time =
internal disks to get started and still do not boot unless I do that =
typing / and then kernel/unix.=20
