^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * Function 0 is an IDE controller. It is identical to a PC87415 IDE
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * controller (and identifies itself as such).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) * Function 1 is a "Legacy I/O" controller. Under this function is a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * whole mess of legacy I/O peripherals. Of course, HP hasn't enabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * all the functionality in hardware, but the following is available:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) * Two 16550A compatible serial controllers
