assuming an empty socket (IBM mobos typically have empty sockets), chances are if you
dropped IBM roms into a clone mobo, while it may not boot into BASIC in the absence of a
floppy or hard drive, would it work if you jumped to so and so?

That depends on the level of "cloneness". In the context of my very
first PC XT clone eons ago, I put a full copy of the IBM ROM BIOS and
ROM BASIC in it, and it went right into BASIC as expected when it
couldn't find a boot device. That was a pretty close copy of the XT
design; the only real difference was the ability to switch the clock to
8MHz from 4.77. It ran IBM BASIC from ROM just fine.

I remember the early clone errors of "No interpreter" when it couldn't
find a boot disk. ;-)

I used to do it all the time. Yes, it works.
