Confused about booting new kernels

[John Klos <john%ziaspace.com@localhost>]

Hi,

The problem I had several months ago still has no resolution. I've 
reinstalled the latest bootblk and ofwboot built from netbsd-7 sources 
from today, then tried booting a new netbsd-7 GENERIC kernel, then 
-current from nyftp.netbsd.org, and still nothing newer than 6.1 boots:

Sun Fire V100 (UltraSPARC-IIe 548MHz), No Keyboard
OpenBoot 4.0, 2048 MB memory installed, Serial #53885934.
Ethernet address 0:3:ba:36:3b:ee, Host ID: 83363bee.



Executing last command: boot
Boot device: disk  File and args:
NetBSD IEEE 1275 Multi-FS Bootblock

netbsd in this example was from HEAD on nyftp, and netbsd.old was from a 
while ago. The bootloader also claims to not be able to load an install 
kernel, too.

Any thoughts or suggestions?

Thanks,
