I've been looking at the hardware specs for the U2 at , and comparing the pages at and . I didn't find a page for the U2E, however. However, looking at these pages, it's not obvious to me what the precise hardware differences are between the different sub-models. > The two are significantly different, and we actually do not support > the "U1".

I think. :-) The U1E > has a HME onboard ethernet controller and a wide SCSI connector > coming out the back. The Lance Ethernet chip should be easy enough to support. If we don't have it, I'm sure NetBSD and OpenBSD do -- how hard would it be to port them? I'm more concerned about the SCSI controller, however. Does anyone have any ideas which specific controllers are included with which machines, and how they are different? Speaking only for myself, I'd like to do what I can to try to help FreeBSD/SPARC64 support all the UltraSPARC machines, including all variants of U1, U2, etc.... -- Brad Knowles, "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -- Benjamin Franklin (1706-1790), reply of the Pennsylvania Assembly to the Governor, November 11, 1755 SAGE member since 1995.
