Customize the EEPROM for Chrontel chip on MIO-series & MIOe-series
2011/10/25_ECG AE
Utility: CH7511B Release V1.01.04
EEROM file: MIO5270.bin
Step1. Enable the DP port function
FOR MIO-series
[Chipset][Display Config Select][LVDS][Enable]
FOR MIOe-series
[Chipset][Display Config Select][LVDS][Disable]
(User needs to disable onboard LVDS)
[Chipset][Display Config Select][HDMI][DP]
Step2. Open the Chrontel CH7511B-Utility. The GPIO item is related to the Panel Type
selection in BIOS setting. For example, choose GPIO 11 for “Customized
Define” to meet with Panel Type selection in BIOS setting.
Step3. Press the button “Launch Chip Wizard”, and follow the below setting to
configure the Chip configuration. (Default setting will be ok)
After setting all items, press “Finish” to back to main window of Chrontel utility.
Step4. Press the button “Launch Panel Wizard”. And follow the default setting from
below pictures.
Kindly refer to the panel spec to adjust the “LVDS Panel Power Sequence”.
We usually adjust the EDID timing in this page. User can select the default resolution
from the list for testing. (Most of LCD panels only need to modify the setting on this
page)
If the user uses a panel with special spec, please choose a similar resolution and
select the “Set manually” item to adjust the detail EDID timing.
(For most of LCD panels, we only need to adjust below setting that marked as red)
Pixel Clock = Hor. Total * Ver. Total * Frame Rate
HA= Hor. Active; HB = Hor. Blanking; HSO = Hor. Sync Front porch;
HSPW = Hor. Sync Pulse Width; HB = Hor. Border
VA= Ver. Active; VB = Ver. Blanking; VSO = Ver. Sync Front porch; VSPW = Ver. Sync
Pulse Width; VB = Ver. Border
Press “Finish” and return to the main window of the utility.
Step5. Press “Export” to export the setting to an image for the customize panel.
Step6. Flash the bin file into EEPROM.
Select the tab “CH7511B Image Copy”, and press the button “Options” to select the
interface for flashing EEPROM.
Choose the “DP AUX” item for flashing the EEPROM. **
**For AMD platform
User can access the AMD DP AUX directly after the graphic driver is installed.
**For Intel platform
Before user access the EEPROM through Intel DP AUX, please install the driver for the
current OS.
Press the button “Import” to import the bin file that for the customize panel.
And press the button “Flash” to complete the process of EEPROM flashing.
After flashed the EEPROM, it need to restart the system to check the panel output.
**If there is still cannot show the correct image on the panel, please go back to Step4
to create a new image to adjust the EEPROM. User should try to adjust the value of
Pixel Clock & HA & VA for testing first.
[Noted]
1. The modified EEPROM can be verified in POST stage, after getting into OS, to
show the modified resolution depends on the driver.
2. If user failed to change the panel timing for other existed resolution, please
flash back to the original bin file.
