>Description:
Bootloader on freshly installed system (Dell 2850) isn't able to see or load 
kernel. Screenshots from remote management are available at:

http://aniou.smutek.pl/netbsd_boot_failp1.jpg and
http://aniou.smutek.pl/netbsd_boot_failp2.jpg

System was installed in very standard way (boot loader at mbr,
defaults for filesystem - modulo / without -o log). 

I was not able to start either by original /boot or copied from
i386 version, BUT both bootloaders from install CD and /usr/mdec/boot
extracted from old 5.99.25 release (i386) works fine.

>How-To-Repeat:
Try install on another Dell/PERC/amd64?
>Fix:
Copy of old /boot from 5.99.25 works for me, but it may doesn't fit as general 
solution for this problem ;)
