System: NetBSD andromeda.noi.kre.to 7.99.21 NetBSD 7.99.21 (VBOX64-1.1-20150829) #3: Sun Aug 30 07:16:17 ICT 2015 kre@andromeda.noi.kre.to:/home/kre/src/current-kernel/usr/src/sys/arch/amd64/compile/VBOX64 amd64
Architecture: x86_64
Machine: amd64
>Description:
	I did an amd64 install onto a new system, on which I thought
	I'd try doing a pure GPT system setup, using sysinst.
	Aside from the sysinst steps to use GPT being a little
	counter-intuitive (the method to use isn't as obvious as it
	could be) all of that worked - except the resulting system
	wasn't bootable.

	Cause of that was that the "gpt biosboot" step failed, and that
	was because there's no gptmbr.bin on the ramdisk

>How-To-Repeat:
	Do an amd64 install of current and format a new empty disk
	(no boot info previously installed) as GPT.  Complete the
	install.  If you're observant you'll see the "gpt biosboot"
	failure error message flash past.  Attempt to reboot.

>Fix:
	The workaround for anyone who is in this situation is to
	finish the sysinst install procedure, then when given the
	opportunity, get a shell, mount the newly installed root
	(and /usr if you separated them) and re-run the
	gpt biosboot using the gptmbr.bin that will have been
	installed in /usr/mdec on the newly installed system

	To prevent this happening in the future, in src/distrib/amd64 ...

	I believe the same is required in src/distrib/i386 but I
	haven't tested that one to be certain.

	I have yet to build and test a system with this change to
	know for certain that it is correct and sufficient, and
	doesn't cause the size of the ramdisk to exceed limits,
	but I am fairly confident that it is what is needed.
	(I will append confirmation once I know.)

 I can confirm now that with the fix installed, a ramdisk based amd64
 install of NetBSD current correctly makes a bootable GPT pdrive.
