I feel that while writing a BIOS, we must provide a small set 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.
