The bits of the WORD Flags are set as follows:

0 = Graphics video mode.
1 = Text video mode.
Bits 1-14 = Reserved and must be 0.
Bit 15 = Default calibration flag.

Notes
The internal calibration table consists of ten sets of calibration
parameters. The valid range for the calibration table index parameter is
0 through 9. If this function is called with a calibration table index
outside this range, the calibration status is set to 01, the calibration table
index value in BL is undefined, and no calibration data is returned.
