So today I was fidling with BIOS Patcher, and decided to load new cpumicrocode for my IC7-G -> modded the BIOS, put it on floppy drive and then... after BIOS flash mobo wont POST (no display).

The board has PhoenixBIOS D686 BIOS chip, but I failed to find any info about it (what voltage it needs to be programmed etc.)

Which BIOS programmer I need to unbrick the mobo?
I looked at some BIOS programmers and the most popular seem to be CH341a, EZP2019, EZP2023+.
Any idea which one to get, what adapter to buy etc.. 😀
Any help is appreciated.

Is that not a socketed BIOS chip. Can you not find a new one?

Remove the sticker.

Right to repair is fundamental. You own it, you're allowed to fix it.

Yes, remove the sticker. My Giga i875 (GA-8iK1100) board has same sticker and the eeprom/FWH is a STM50FW040...mine are soldered.... 🙁

Is a 4Mbit like the ST. The TL866ii does support it.

Depends on what package you bought. there are versions without any adapters, and there are versions with different adapters.
If I read it right, you'll need a plcc32 adapter.

Yes you want a PLCC32 to DIP32 adapter, they are very inexpensive if you do not have one. Another good one to have is the PLCC32 to DIP28 (for chips like AM27C256 that come in DIP28 and PLCC32, that way you can program the PLCC32 version)....
added: if you have no adapters suggest getting something like this set: https://www.aliexpress.us/item/3256803471093016.html
Those five are the ones I have used the mst...

After ordering XGecu T48 and waiting few weeks, I can now report that ABIT IC7-G with Pm49FL004T BIOS chips is saved and rocking again.
Thanks to everyone for help!
