I have two Dell 2850's happily running Solaris 10 ( with the most recent
patch cluster just applied ) however I would like to boot to the
failsafe option at start up to take regular ufs dumps of root.

However when I do this it reports no operating system found and format
also reports no disks found.

How can I either modify the failsafe miniroot and/or modify a CDrom's
mini root to add the LSI image
driver(http://www.sun.com/download/products.xml?id=431fd1be) so I can
access this disks.

Ideally I want to be able to use both methods.

I hope this makes sense and thanks for your help.
