Initially I had a problem when trying to install the system from the CD. It was the radeon card... It gave a "panic: cnopen: no console found" error and failed (entering the debugger). Prior to that a drm error is given. kern error: [drm:(/export/netbsd/src/sys/external/bsd/drm2/dist/drm/radeon/radeon_bios.c:725)radeon_get_bios] *ERROR* Unable to locate a BIOS ROM radeon0: autoconfiguration error: error: Fatal error during GPU init radeon0: autoconfiguration error: unable to attach drm: 22 I remember that I had the radeon1 also, there were two of these drm errors, as far as I can remember. So I could not pass this point. So I disabled radeon to install the system, and wrote a boot.cfg to use gop and disabling radeon. > > 2.
