Chip is either recognized, or not. What do you mean by "not properly"?

If you have a dump then yes, you can restore the BIOS, if not you can find one from another system and try that. Best to dump chip first and have that checked out, before you try to erase or write anything, BIOS is most likely 100% fine.
It sounds like you have a short, or had a short while connected and now some resistor or voltage protection circuit blew out, etc. Since you connecting with programmer should not have done anything to the BIOS, unless you accidentally erased it.
Sometimes smoke may not appear, or you may miss it as it's not very much at all. Can you show me close up images of area around the BIOS chip, sometimes you can see blown trace or resistor

But really, I need more info about what I asked above too, to better understand what is really going on here. Please dump the chip and send me the contents.
You may need to have main battery installed and or PSU connected (But not system powered on), or you may need to remove main battery and disconnect PSU (Some systems need one way, others the other way)

@mediadoctor - Please upload a programmer dump of your BIOS, I will check and let you know.
Also, please give your full exact model name, and or link your exact model BIOS download page, there is 8 x Triton 500's This way I can download your stock BIOS on Acer site.

@mediadoctor - sorry I've missed your replies for so long!! I'm always buried here

Did you ever dump your BIOS, before you wrote to the chip? If yes, please put in zip and send to me (if zipped file is only few KB's then never mind, that is blank dump)

For MX25L12872F you need to use ASProgramer, so I bet for MX25L12873F you should too, here get 1.41 - https://github.com/nofeletru/UsbAsp-flash/releases/
If you did not get a good dump before you erased/wrote, then all original system details will probably be lost forever, unless there are on stickers on the board. Really only important one is LAN MAC ID, but you may be able to find and recognize that in your router logs
Good news, I think I have BIOS region dump from you, maybe from software, before you bricked BIOS.

If you never dumped with programmer, then I will have to find a BIOS dump from your exact model, or see if I can rebuild you new BIOS from scratch. You cannot write BIOS from Acer, unless you email them and tell them you need a recovery.bin file for this model.
