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.
