You can't use this with biosdisk, since the normal buffer for other calls
of INT 13h use ES:DI as the pointer. So, you'll have to use __dpmi_int
directly. The code will look something like this.

__dpmi_regs regs;
regs.h.ah = 0;
regs.h.dl = driveno;
regs.x.ds = __tb/0x10;
regs.x.si = __tb%0x10;
__dpmi_int(0x13, &regs);
if(regs.x.flags & 1) {
	printf("Failed\n");
}
else {
	// Your parameter details are in the transfer buffer.
}


Actually, I remember this as being some other function (not 48h). Anyway,
