With the full disc1, I lock up even before the "jumping to kernel entry line: FreeBSD/sparc64 bootstrap loader, Revision 1.0 (root@binkley.cse.buffalo.edu, Sun Apr 17 07:33:09 UTC 2005) bootpath="/pci@1f,4000/scsi@3/disk@6,0:a" - Note that the hyphen above is the third character in the spinning effect. This is very repeatable on my system - locks at the same point every time, right after the | and the / . I just double-checked both MD5sums; I have no idea why I'm getting different behavior with the two ISOs. Simplest answer is that there's something wrong with one, but I can't find anything on my side. Unfortunately, I'm leaving town for a week and so won't be able to do any further testing for you. I hope that Dieter and/or Gheorghe can pick up the baton. -royce -- ------------------------------------------------------------------------ Royce D.
