75 | * HCI is Toshiba's "Hardware Control Interface" which is supposed to | |
76 | * be uniform across all their models. Ideally we would just call | |
77 | * dedicated ACPI methods instead of using this primitive interface. | |
78 | * However the ACPI methods seem to be incomplete in some areas (for | |
79 | * example they allow setting, but not reading, the LCD brightness value), | |
80 | * so this is still useful. | |

82 | * SCI stands for "System Configuration Interface" which aim is to |
83 | * conceal differences in hardware between different models. | |
