/* The IMCR is supported by two read/writable or write-only I/O ports,
22h and 23h, which receive address and data respectively.
To access the IMCR, write a value of 70h to I/O port 22h, which selects the IMCR.
Then write the data to I/O port 23h. The power-on default value is zero,
which connects the NMI and 8259 INTR lines directly to the BSP.
Writing a value of 01h forces the NMI and 8259 INTR signals to pass through the APIC.
