Doesn't this require newer hardware/BIOS/firmware than most
equipment has these days?
I'm pretty sure that my ASUS box with a Toshiba 3401B won't
boot from one of these, except on my really old AHA1742,
which can't tell it's not just another hard drive...
Is this going to be the default for distribution, or is the
"fake floppy" boot CDROM still going to be "disc #1"?
