2. Set Address decoder 0 to decode 0x380~0x387:
outportb(0x4e, 0x77);
outportb(0x4e, 0x77); //Entry configuration mode
outportb(0x4e, 0x07); //Select register index 0x07
outportb(0x4f, 0x06); //Select LDN 6
outportb(0x4e, 0x60); //Select LDN 6 register index 0x60
outportb(0x4f, 0x03); //Set Address decoder 0 base address high byte to 0x03
outportb(0x4e, 0x61); //Select LDN 6 register index 0x61
outportb(0x4f, 0x80); //Set Address decoder 0 base address low byte to 0x80
outportb(0x4e, 0x62); //Select LDN 6 register index 0x62
outportb(0x4f, 0x03); //Set Address decoder 0 base address mask 3 bit
outportb(0x4e, 0x30); //Select LDN 6 register index 0x30
outportb(0x4f, 0x01); //Enable Address decoder 0 Device
outportb(0x4e, 0xaa); //Exit configuration mode
3. Set Address decoder 1 to decode 0x480~0x480:
outportb(0x4e, 0x77);
outportb(0x4e, 0x77); //Entry configuration mode
outportb(0x4e, 0x07); //Select register index 0x07
outportb(0x4f, 0x07); //Select LDN 7
outportb(0x4e, 0x60); //Select LDN 7 register index 0x60
