Subject: Re: port-sparc/37080: second stage boot loader fails on SparcStation 2

 Here you are... unfortunately, there is only the message
 "Data Access Exception" which is AFAIK emitted by the firmware.
 The protocol shows two attempts to boot from a CD containing
 the RC1 ISO image, a successful boot from HD (using the
 second-stage boot loader from NetBSD 3.1) to show the configuration
 of my machine and an unsuccessful attempt to boot the RC1
 miniroot image.
 
 The only clue I get is that my SS2 has ROM revision 2.2,
 whereas yours has revision 2.9.
