Not really..

--8<-- nunimbr.asm
iobase          equ start-8     ;overlay some variables
ext_start       equ start-4
 mov AH,2               ;check for shift, ctrl, or alt
 int 0x16
 and AL,0xF
 jz f1                  ;use default if none pressed
prompt                  ;errors jump to command prompt
 call Input

It uses BIOS interrupt services to read and write characters.

While the code is trivial and easy enough to replace with serial io
nuni is in no way completely independent of a BIOS.
