/* Our private DDC functions

|
|
|
It complies somewhat with the corresponding VESA function
|
|
in arguments and return values.
|
|
|
|
Since this is probably called before the mode is changed,
|
|
we use our pre-detected pSiS-values instead of SiS_Pr as
|
|
regards chipset and video bridge type.
|
|
|
|
Arguments:
|
|
adaptnum: 0=CRT1(analog), 1=CRT2/LCD(digital), 2=CRT2/VGA2(analog)
|
|
CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
|
|
LCDA is CRT1, but DDC is read from CRT2 port.
|
|
DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
|
|
buffer: ptr to 256 data bytes which will be filled with read data.
|
|
|
|
Returns 0xFFFF if error, otherwise
|
|
if DDCdatatype > 0: Returns 0 if reading OK (included a correct checksum)
|
|
if DDCdatatype = 0: Returns supported DDC modes
