I think that Chuck meant software interrupt calls into the BIOS, which
was the more-or-less official way of making BIOS calls (eg, INT 10h,

Also, JSR isn't an x86 instruction. I think you mean "CALL". :P

At least one "PC incompatible" provided
a
terminate-and-stay-resident DOS program that translated PC BIOS
calls to the native system's BIOS.
I can't see how that could possibly work when you're operating in
real mode and you JSR to a specific ROM address.
