	I love bsdi boot.default.

	actually boot.default is IMHO a "must have" when trying to boot on
	laptop from floppy - there are too many laptop PCs in the market
	with non-standard IRQ settings, or non-supported hardware.
	Without having someone to bake boot floppy for you, there is no
	way to install and can become obstacle to newcommers (or even for

	To list some items I encountered:
	- Sony Vaio505FX (called "505EX" in Japanese market) uses non-stanard
	  irqs, which prevent standard boot floppy from using pcic.
	- Digital HiNote Ultra II has second pcic, which should be manipulated
	  in polling mode.  last time I've tried booting netbsd boot floppy,
	  pcic was probed as if it has no slot and there was no way other than
	  make a special boot floppy.  PR 7908.
	- TP570 and NetBSD-current pciide are not friendly.  PR9039.
