Re: Boot fails on Sun Ultra 45
Thank you for this idea. I saw some posts about earlier Sun Ultra
models having a limit of 4 gb for the root partition. I reinstalled
with a boot partition of 4 gb, and the firmware was able to find all
the files it needed to boot successfully. Thanks to all for your
help.
