Is there a need to jump to some other place after
A20 is enabled?
What's the relationship between A20 & Pmode?
Thanks.

Certainly not.

A20 has to do with the architecture of the pc,
when enabled it gives the software the ability
to address memory above 1meg. Once A20 is enabled
some other lines become available as well, giving
you access to up to 4Gig of RAM. It's used in
pmode to take advantage of the rest of the ram
a system has to offer.
