There is a program that is relatively large and runs in the protected mode of DOS through DPMI, but this program needs to call an interrupt-resident program. This interrupt-resident program is resident in the conventional memory of the real mode, but this interrupt-resident program needs to access the extended memory in the protected mode according to the passed-in segment address and offset address. How can it be accessed?
