I think he was asking about the BIOS flash, not the Chrontel.

ollopa, that's correct. I've messed up and butchered my  AIMB-581 board when tried to install a new BIOS release provided by Advantech.
Ordered a cheap CH341A SPI programmer for $14 from Amazon and hope to re-flash and revive it.

I assume you're going to try flashing the V118 BIOS I posted if you have a 581.

I removed the SPI flash chip this morning and dumped with my TL866.  The contents are almost identical to the stock Advantech BIN except for areas where I assume the settings are stored, so you can probably flash the V118 BIN directly.  But in case you're curious or you need it, here is this morning's dump from my working board:

ollopa, thanks! I do have the old BIOS dump from my board, I just need to re-learn all the modifications I did back in early 2017 to this BIOS. That was version 1.1.5 which was correctly working with my LCD. However, I started to mess with it and "upgraded" intel ME hoping to unlock CPU multiplier in Q67 chipset (my CPU has unlocked multiplier, but chipset doesn't allow it). The newer version of ME messed up my USB host controller, and when I got a new BIOS ver. 1.1.8 from Advantech I was hopeful that I can reflash all regions including ME and will get my USB working again. However, as you already probably guessed, instead it resulted in total disaster and my board is dead now. My plan is to use external SPI programmer to flash my old 1.1.5 dump back. Also I will try to recover board-specific info like UUID, etc so I won't have to re-install Windows 7.

Is it possible to use the Lecroy ZS-Probes with the WavePro 7300a? At least in the version upgraded to windows 7 and the latest possible Lecroy software?

Hi Converter,

Thank you for your post about Chrontel utility, saved my life. My problem is described in the below link and I need this secret, (almost) nowhere to find tool to be able to mess up with LVDS bit mapping of my SBC. Happy to find this forum, it is amazing for me how many people with in depth knowledge and experience posting here.
