From: rueve AT uni-muenster DOT de Subject: problem callinf DOS interrupts that use ES To: djgpp AT sun DOT soe DOT clarkson DOT edu Date: Fri, 29 Apr 1994 10:13:42 +0200 (MES) Hi folks ! I have been unable to resolve the following problem : To call some software-interrupt (one of the int 0x33 services to be exact) I need to pass a segment-register to tell it where it can find some data (the mouse-pointer). Doing this via int86x (the one you can pass the segment-registers along with) does not yield the wanted results but a system crash ! I am using DJGPP 1.11m4 with GCC2.5.7. Also I am unable to use the -O or the -O2 options ! Bost of these yield unexpected (or unsupported ? I do not remember) interrupt 0xd. Anybody any ideas on these two ? CU Michael
