Interrupts / Clean up int21 handling
Jukka Heinonen
jhei at iki.fi
Mon Dec 2 14:01:52 CST 2002
This patch cleans up int21 handling and prepares for
migration of nontrivial functions to winedos.
Winedos no longer uses INT_Int21Handler as default
handler for unknown functions.
Changelog:
Clean up int21 handling. Move error handling to winedos.
Call INT_Int21Handler only to emulate selected functions.
