Footnotes

        [1]   The 83-key and 84-key keyboards are the original PC keyboard
              and the original-layout AT keyboard, respectively.

        [2]   The 101/102-key keyboard is the current IBM standard
              ("Enhanced") keyboard.

        [3]   "Standard Function" refers to Interrupt 16h Services 0, 1,
              and 2.

        [4]   "Extended Function" refers to Interrupt 16h Services 10h,
              11h, and 12h.

        [5]   In the United States, the 101/102-key keyboard is shipped
              with 101 keys. Overseas versions have an additional key
              sandwiched between the left Shift key and the Z key. This
              additional key is identified by IBM (and in this table) as
              "Key 45."

        [**]  Keys and key combinations marked ** are used by the ROM BIOS
              but do not put values into the keyboard buffer.

        [--]  Keys and key combinations marked -- are ignored by the ROM
              BIOS.
