     18 * We need PC style IO addressing for:
     19 *  - floppy (at 0x3f2,0x3f4,0x3f5,0x3f7)
     20 *  - parport (at 0x278-0x27a, 0x27b-0x27f, 0x778-0x77a)
     21 *  - 8250 serial (only for compile)
     22 *
     23 * These peripherals are found in an area of MMIO which looks very much
     24 * like an ISA bus, but with registers at the low byte of each word.
