Thank you for all your help.

Thank you Kaos. On these mobos I spend a lot of time reworking the chips, burning them and then re-soldering them back on the mobo. When flashing BIOS chips, is there a way to burn .BIN files on a bootable USB or CD to load a dual BIOS mobo? I was thinking to take the .BIN contents from these chips and adding them to an exe BIOS that was previously created for the system, and just change the content of the write to the BIOS. Is that possible?

I ended up comparing the spec sheet of both chips. They aren’t even in the same Voltage category lol. I guess I won’t be using them. Found some used ones on eBay, will order them. and.. surprisingly both the BIOS chips worked. The ones I thought I burned without proper adapter. I ended up using the MiniPro (although had many read and write failures) annd eventually was able to rework them into the mobo and they booted up alright. Thank you for all your help Kaos. You’re a badass.

Here is the picture of the MX chip:

I had another question. I’m also trying to flash/clone the following 32 PLCC MX chip: MX29LV040CQC-70G IMG_3772.heic I couldn’t find the chip anywhere, been discounted. Instead I found a replacment from digikey: SST39SF040-55-4I-NHE-TCT-ND After seeing the troubles I’ve had with the SST chip, what’s the best way to verify these 2 above chips they have the same pin outs or close enough that I can clone one to the other successfully? Or am I just wishful thinking.

Thank you Kaos! I suspect a dedicated BIOS reader from South Korea will be 10x better read write quality than anything I can get from China. Ordered. ——— Before connecting anything I’ll see if I can dig up some diagrams of each programmer to see they match the ADP-005 I’m pretty sure it’s XGecu clone. It’s a TL866CS Programmer. Found it on Amazon. https://a.co/d/7K2Pd8A

I looked up online and I found a programmer called MiniPro and another XGecu T56 that seem to support the chips, and don’t seem to require adapters. Are you familiar with these? Would I need an adapter board for those?

Damn, but ty. I can measure the voltage on the programmer, but if you’re right about VCC being 5 VDC, then I just fried 2 of these chips On the forum I saw you guys were using a different programmer to flash these chips. Do I need special adapters for that programmer as well?

Thank you for replying. I just checked all the pin outs with a multimeter, pin 1 through 32 all correspond correctly from the SST chip to the DIP 32, from the diagram above. I looked up on the GQ website and I see they have an adapter requirement for this particular SST chip. They say to use: ADP-030, ADP-057 FWH/LPC+ Apparently these adapters have special pin outs that are shorts somewhere, and that’s how it’s possible to read and write the chip. Do you by any chance have have the pin out for the above adapters? I could just modify my ADP-005 with some lines and see if that works. Again, thank you for your help.

Hi KaosEngineer, and everyone:) I wanted to flash a SST49LF080A*PLCC32 bios chip. I’m using GQ4x4 with ADP-005 adapter. But I keep getting ID check failed, and device is showing empty. I know the device isn’t empty. So, I’m assuming my adapter pin outs are not correct. Do you by any chance know the correct pin outs to flash the above bios chip so I can modify my ADP-005 (PLCC32-> DIP 32) adapter? I tried looking online for this info, but hit a brick. Thank you very much for your help.
