From 503af721a1f2c831fb360d1c1b2af38e0866fc35 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 22 Nov 2012 10:48:18 +0100 Subject: x86 realmode: Adapt to x86emu/YABEL style return codes realmode int handlers must return the same codes as the YABEL int handlers now: 1 for "interrupt handled", 0 for "not handled" (ie. error).
