Need more info. That 915a05-pl-6ls may be the BIOS string but is not the motherboard model. We need the exact board model number. It would be 915PL something...
Can you post a few good pictures showing any labels on your board.
If it was a retail board the archives have a list. If it was strickly OEM it may not be on that list.

this site has mirror of the same retails list: https://us.driverscollection.com/?V=Foxconn&S=4

All these foxconn 915PL boards that looks similar to yours are using the same bios, and the latest one is 4C4F1P23
If you have an eeprom programer, just dump the bios and compare the 2 bios string.

if the board freezes on post screen it could be a dying south bridge chipset.
also are there any bulged caps on the board?

Seeing is believing so:

Funny thing- Sticker says Phoenix, Screen says Award... But is a pretty big .bin file, so the Screen wins.

As you can clearly see, it says Bios is corrupted as a politician... So making a copy of it... I do not see a point in it. May be I will make backup to see if something is readable but do not have hi hopes.

Something else: While Looking For 1.44 disks and a working floppy, Tried key combo to start some recovery mode, and something started but the whole screen got filled with scrambled numbers and letters- another sign for corrupted rom.

No freezes , just gets in this Safety option/mode. Sometimes even shows The Videocard Identification before the screen above
It had a 0.8v battery but already swapped it with a brand new cell.
Caps are perfect, top and bottom. If it comes to live and full function after the flash , will take some caps out to measure ESR and if needed replace all of them ,it is not an issue for me.
Unfortunately comes from home with a dog and smoker and was filled with musty brown dust. I have already clean it

you need a bootable floppy and 4C4F1P23 bios package from here: https://www.helpdrivers.com/motherboards/Foxc … 775/915PL7AE-S/
copy the AFU865.EXE and 4C4F1P23.BIN to the floppy then edit the autoexec.bat file with this line:
AFU865 4C4F1P23.BIN /cc /py /sn /r

as soon as you turn on the board it should start reading the floppy and recover the bios.

Thank you for the support, mate.

It has a working BIOS now
