Share your knowledge/info. Why do you suspect it's wrong?
Say [like a lawer]:
< A is xyz, and B is klm, therefore C is uvw>

I haven't seen the [assumed original IBM/MS] BIOS specs for decades.
? vaguely believe that booting uses interrupt 13,
 which probably happens after/if the POST-test passes.

So, on reset, is POST first?
Is POST a standard intrpt, or is it customised in the particular PC's ROM,
which reset 'vectors' to ?
