The DAC can also be read by way of the BIOS in either of two ways.

`INT` 10H, function 10H (AH=10H), subfunction 15H (AL=15H) reads out a
single DAC location, specified by BX; this function returns the RGB
triplet stored in the specified location with the red component in the

the blue component in the lower 6 bits of CL.

Listing 34.1 illustrates reading the DAC both through the BIOS
block-read function and directly, with the direct-read code capable of
conditionally assembling to either guard against interrupts or not and
to use **REP INSB** or not. As you can see, reading the DAC settings is
to use `REP INSB` or not. As you can see, reading the DAC settings is
very much symmetric with setting the DAC.
