I feel that while writing a BIOS, we must provide a
of very poweful operations instead of bloatingt the BIOS to include
one & all. I am strongly for adding prot-mode code, but only when
necessary. wheras prot. mode code will add extra bytes in size,
the advantages are obvious. However, IMHO, one should not just
rewrite the entire BIOS using prot. mode. Real mode code does
have its advantages, esp. in areas where mem. consumption is
not so critical.
The real mode vs. prot. mode:
If you want to support DOS, you have to rewrite the normal BIOS
in real mode. Any protected mode extensions can't use these
functions and have to reimplement them.
If you wan't to boot from protected mode, you need your own
SCSI-drivers, small VGA-Drivers and so on.
