Hello, I have an Display Signage Unit from Innes, DMC200. Wanted to install an operating system on it, since the company closed, I was having issues with the display image, the unit comes with DVI interface, but I guess it is implemented differently, it only works when the OS loads, so it must be activated by some sort of program, but for Bios and pre OS image, the VGA was working…bad, but I had an image, so I was looking in the bios for something about the image and I found setting for display panel that said Display panel 1 thru 9, mine was set to 2, tried 1, nothing, tried 3, the image changed, different bad image, so I continued, 4 was better, then at 5 I had no more image.
The unit still works, I can tell from the LEDs and, posts and everything, but I don’t have any display image anymore, the VGA sends a signal, but out of range, tried every monitor I had on hand. I thought, no problem, just reset the bios and try again, but this thing has an Toradex Z530M module, and this has an Firmware HUB, not a standard bios, where you just reset the bios battery and all settings are reset. This has the settings written to flash, doesn’t matter if you lose power, or clock battery. So how do I reset the bios setting on this module, or if there is a key combo to force the display to standard VGA, please help. I cant find anything on the internet.

Hello,
I understand you’re facing a challenge with your display signage unit using the Toradex Z530M module, particularly with resetting the BIOS settings to restore display output. Here are a few steps you might consider trying:
-
Access Recovery Mode: Some embedded systems have a recovery mode that can be accessed during boot. This might allow you to reset the settings to default. You could try holding down a specific key during power-up to see if this triggers a recovery mode.
-
Use a Serial Console: If your device has a serial console interface, you might be able to access the BIOS settings through it. This would involve connecting a serial cable to the appropriate port and using a terminal program to interact with the system.
-
Re-flash the Firmware: If the above methods do not work, re-flashing the firmware on the module could restore the default settings. This process requires access to the correct firmware image and flashing tools.
These steps are intended to help you regain display functionality. Please proceed with caution, especially when re-flashing firmware, as it can affect the system’s operation.
I hope this helps you resolve the issue.
Best regards,
Toradex AI Assistant

Hi @CAT !
Welcome to Toradex Community! 
Feel free to browse around!
This must be a Toradex Robin Z5xx module: Robin Z5xx | Toradex Developer Center. This module has been phased out since a long time ago (~10 years) and we do not provide support for it anymore.
Having said that, you might find some useful documentation in here:
For example, I searched like this on DuckDuckGo:
robin Z530M site:developer-archives.toradex.com
And I found: https://developer-archives.toradex.com/knowledge-base/reflash-broken-bios-with-help-of-bumblebee-robin/
Hopefully you will find something useful. Please be aware that any documentation is provided as is since there is no longer support for this module.
I hope it is helpful 
Best regard,
Thank You! I found bios files, but the archives all have passwords, do you know the password? I couldn’t find anything in the pages.
Hi @CAT !
Could you please share where did you get the file from?
I do not guarantee I will find the password, but I can try.
Best regards,
Hi @CAT !
After checking with our a more experienced colleague, seems like we won’t be able to help you much.
Innes most probably designed their own carrier board with their own configuration for BIOS and OS (e.g. switching display routing from VGA to DVI) and Toradex does not possess their custom BIOS/OS.
A side note was also shared with me: the BIOS is copied to RAM and Flash, but the config from flash is read when its checksum in RAM is bad (i.e. battery dead, using flash as restore).
Best regards,
