Subject: DPMI: Interrupt vector overwritten
Date: Wed, 16 Oct 2002 23:07:45 +0100 (BST) [thread overview]
Message-ID: <E181wKP-00022Z-00@seasip.demon.co.uk> (raw)
These lines come from /src/dosext/dpmi/dpmi.c, line 1328 or so. They cause
dosemu to abort if DPMI function 0x300 is used to call interrupt 0xE0 or
higher; is this correct, and if so, why is it doing it?
if (inumber==0x0300) {
REG(cs) = ((us *) 0)[(_LO(bx) << 1) + 1];
REG(eip) = ((us *) 0)[_LO(bx) << 1];
if ((_LO(bx) >= 0xe0) && (REG(cs) < 0xf000)) { /* avoid hardreboot
!! */
D_printf("DPMI: Interrupt vector overwritten!");
leavedos(99);
}
