What I meant is that DOSEMU itself could do int15/87h.
It would just have some virtualized raw extended memory where this
function copies to/from.
The GDT that ES:SI points to would just be used as a block of information,
rather than as a real GDT.
int15/87 now simply does:
else { /* AH = 0x87 */
x_printf("XMS int 15 block move failed AX=0x%04x\n", (u_short)REG(eax));
LWORD(eax) &= 0xFF;
HI(ax) = 3; /* say A20 gate failed */
CARRY;
}
