Int 62 Fn 004E  u - Fgdriver V4.02 - "fg_getrgb" - Get Video Dac Register  [V]

   AX = 004Eh
   ES:BX -> variable pointer record (see #3157)
   CX = DAC register number

Return: variables updated

Notes: the FGDRIVER functions are rearranged with each major release, but
     their parameters do not change (see #3145 at AX=0000h)
   This call is ignored in text modes and CGA/EGA video modes (since
     they do not use DAC registers)
