- * Protected I/O ports. Some ports are always illegal, and some are

- * ports are only illegal if the BIOS calls _OSI with a WinXP string or
- * later (meaning that the BIOS itelf is post-XP.)

- * PIT1: System Timer 1
- * PIT2: System Timer 2 failsafe
- * RTC: Real-time clock
- * CMOS: Extended CMOS
- * DMA1: DMA 1 page registers
- * DMA1L: DMA 1 Ch 0 low page
- * DMA2: DMA 2 page registers
- * DMA2L: DMA 2 low page refresh
- * ARBC: Arbitration control
- * SETUP: Reserved system board setup
- * POS: POS channel select
- * PIC1: Cascaded PIC
- * IDMA: ISA DMA
