|Kind of like the way very early computers--commodore, tandy and IBM PC--had BASIC on rom chips?|
Since motherboards now don't have option ROM sockets I think the only practical way would be for someone to design an add-on card having its own bios with that feature. The motherboard bios would do its thing and then 'hand off' to the bios on the card. There used to be a lot of bios feature cards back in the old days. There were some to fix the Y2K bug and others that allowed the bios to see larger hard drives. I guess most video cards are that way too.
Then the card would load the software into memory--maybe in a ram drive.
If it's possible at all I think that's probably the only way it would work with today's hardware and OS's. It still wouldn't be that easy to do and I don't know that it would be faster either.
