Here we go... I'm new at NetBSD & such

I have a Color classic.  I have installed All but the games12 and comp12
pkgs, they will come after I have a bootable system.  I have tried the
netbsd12 kernel G9, G15, G17 and ADB160 with no luck.  I have removed my
Impact 030 accelerator and gotten further along in the boot process, but
still no luck.  I seem to crash and freeze up with some soer of dump
shortly after the Berkley copyright notice.  Any suggestions, or am I hosed?
