hp aio : netbsd won't boot ...

[Mayuresh Kathe <mayuresh%kathe.in@localhost>]

okay, i finally got myself a low end machine at an affordable price.

the problems started after unpacking the machine.

netbsd 6.1.4 (amd64) install cd just won't boot.
after fiddling around with the bios (which looks like uefi), it booted, 
but refused to install, after some more coaxing moved till the "newfs" 
execution phase and then barfed.

i tested with a bunch of other operating systems (ubuntu 14.04 and 
omnios), which it install and boot up like a charm.

at the moment, have upgraded the memory to 4gb, and run netbsd 6.1.4 via 
virtual box under ubuntu (desktop) 14.04, but the resource consumption 
is crazy, i can't even fire up firefox while running netbsd in that 
mode.

any ideas about how i could make netbsd work on bare metal?
or should i simply upgrade the memory to a total of 8gb (which is going 
to be quite difficult a proposition at the moment)?

thanks,
