 I suspect that you might be encountering an overly cautious
 install procedure that is trying hard not to lose any data on
 your system's disk (even when it does not need to.)
 
 My assumption is that you want to install NetBSD onto this system
 and that the disc has nothing at all on it that you need to preserve.
 
 If that is not correct, stop reading this message now, and do not
 do what I am about to suggest.   Instead send a reply message,
 and in it, include some more information about your hardware (what
 kind of processor (amd/intel, which model?), how much ram, what size disc)
 and also what image and method you're using to boot - are you booting from
 the network, from a CD (of DVD) image, or from a USB stick, and which
 image (obtained from where) did you boot.
 
 But if you are wanting to completely destroy any data on the drive,
 try booting the install image, then exit from sysinst, and at the
 shell prompt that results do
 
 	dd if=/dev/zero of=/dev/rwd0d bs=32k count=1000
 
 But beware, this will (effectively) destroy all data on your drive
 (not good enough, not even close, to avoid experts reconstructing some
 data, but enough that no-one here is likely to be able to assist with that.)
 
 When that finishes, simply reboot (you can type "reboot" probably,
 but if not, just power off and start again) and this time try doing a
 normal install all over again, from the start - and it might just work...

 ps: console=pc,speed=9600 to installboot is a strange combination of
 options, speed is normally only used with com port consoles, it is not
 required for a "pc" (ie: display and keyboard) type console.
