[SunHELP] Boot cdrom on ultra10

[anna menshch]

 You where right, the alias for the cdrom was wrong. It was
devalias
cdrom /pci at 1f,0/pci at 1,1/ide at 3/cdrom at 1,0:f
 instead of
devalias
cdrom /pci at 1f,0/pci at 1,1/ide at 3/cdrom at 2,0:f

So I set nvalias of cdrom to the correct value, and it works.
Is there a way to deleted the wrong entry?  I look at all the aliases and
there are at least four entries for cdrom, several for each disk.  It is
confusing.  I understand that the first value in the list gets read, but if
there is a way to delete unwanted values, it would be great.

Thanks,
Anna

 That is fine, and makes more sense. Can you please
read the rest of the email that I sent to you? It
contained alot more than that first paragraph that you
replied to. (Either re-read it, or read this email
completely to the end (or the second instance of
"-david"))

 Also, where you mentioned the following:

 This is quite normal. The u10 is not a SCSI based
computer (unless you added a SCSI controller and some
SCSI devices to it). And probe-pci is not a valid
OBP command. In my last email post to you, I gave you
the command that will also list the PCI devices in your
system.
