Abstract

Mode support systems and methods. The system comprises a storage device and an editing unit. The storage device comprises a first mode list comprising a plurality of display modes. The editing unit edits at least one supported display mode from the display modes in the first mode list, and stores a second mode list comprising the supported display mode to the storage device. The supported display mode in the second mode list is retrieved by a device.

Claims

1. A mode support system, comprising:

a storage device VBIOS (Video Basic Input/Output System) storing a first mode list comprising a plurality of display modes;

an editing unit editing at least one supported display mode from the display modes in the first mode list, and storing a second mode list comprising the supported display mode to the VBIOS;

a driver of the VBIOS, retrieving the second mode list from the VBIOS, and obtaining the supported display mode in the second mode list; and

an OS (Operating System) of a device, retrieving the second mode list directly from the VBIOS, and obtaining the supported display mode in the second mode list.

2. The system of claim 1 wherein the OS further retrieves the second mode list from the VBIOS by way of the driver, and obtains the supported display mode in the second mode list.

3. A mode support system, comprising:

a storage device VBIOS (Video Basic Input/Output System) storing a first mode list and a second mode list, in which the first mode list comprises a plurality of display modes, and the second mode list comprises at least one supported display mode, the supported display mode is one of the display modes;

a driver of the VBIOS, retrieving the second mode list from the VBIOS, and obtaining the supported display mode in the second mode list; and

an OS (Operating System) retrieving the second mode list directly from the VBIOS, and obtaining the supported display mode in the second mode list.

4. The system of claim 3 further comprising a driver receiving a direction from the OS, and retrieving the second mode list in response thereto.

5. The system of claim 3 further comprising an editing module editing the supported display mode in the second mode list.

6. A mode support method, comprising:

providing a first mode list comprising a plurality of display modes in a storage device VBIOS (Video Basic Input/Output System);

providing a second mode list comprising at least one supported display mode in the VBIOS, in which the supported display mode is one of the display modes;

a driver of the VBIOS retrieving the second mode list to obtain the supported Display mode; and

an OS (Operating System) retrieving the second mode list directly from the VBIOS to obtain the supported display mode.

7. The method of claim 6 further comprising the OS retrieving the second mode list from the VBIOS by way of the driver, and obtaining the supported display mode in the second mode list.

8. The method of claim 6 further comprising editing the supported display mode in the second mode list.
