yeah at this point you either need to program with an external programmer or do some hot swap on another mobo while it is working - tricky and dangerous IMHO
where are you located? maybe someone is close and can help!

Hi,

I'm in Geneva, I doubt there will be someone with a programmer around me. I can buy one, but I need to know which one 🙁

the TL866CS or TL866A are a great choice
nowdays I think there is the TL866-II new version or something, any will work just fine

Did you reset the CMOS with JP2 according to the manual after flashing ? Could be a bad eeprom and it should have erased and then written the sections. The picture shows white blocks which usually means it was successfully written.

Do you have a P2 Mainboard or P3 with such IC ?

you can flash by Hotswap with Uniflash Programm.

Bootup your P2/p3 Mainboard, remove BIOS Chip very carefully (better lose it a bit before booting) you should avoid making short circuits 😉, put in your Shuttle Chip and Flash with Uniflash the desired File.

A BX440/LX440 should use similar Flash IC.

Uniflash:

Well, I was so upset I ordered a programmer tl866 II new version. It should arrive on wednesday. I'll try to avoid the hotswap method if possible. I have a p3 mobo with a Via chipset, looks like using the same kind of eeprom but not sure.

However, I'll probably need some help to use the programmer 😁

I think I found the root cause of the crash... Instead of using a floppy to avoid any corruption issue, I prefered to use a HDD freshly 2GB partitioned / formatted, booted with a fresh ms-dos floppy and started the flash from the HDD...
This morning I connected the HDD back to my main computer to copy the "old" flash to my computer, and noticed that If I can copy the OLD.BIN file, windows says the updated bios file 591PS025.BIN can't be copied/read due to corruption...

Just waiting to receive the tl866 now. Any advice when using this app ?

very easy to use

1. press this button and enter W29EE010 (or whatever the chip you want to program is - for your 591P it is W29EE010) - notice on the small window the placement of chip in socket, this appears if you press the "information button"
2. load the BIN file 591PS025.BIN and load it, just press OK and don't change any options on the next window
3. press the "program" button
4. wait a little and it's done

Many thanks, can't wait to receive it 😀

Hi guys,

Quick update... It's alive ! 😍
I received the tl866 II plus today.
I started to "read" it and saved the file for further investigation 😉

Then I've flashed the eeprom with last Bios version. It's been done very quickly.
And now the computer working fine again 🎉🤗

Good Job ! You will find having a TL866 will be very useful once in a while or a lot 😀
Can you post the "bad file" zipped ? We can hex edit and compare and maybe get an idea what happened when you wrote it to your hard drive (or maybe not ;p)

Nice work! I think there will be a TL866 in my life sooner or later too.

Hi,

Here it is 😀

I tried to have a look between what was read from the eeprom and what was supposed to be on it. Actually not that much difference but what seems to be a "big hole" between lines 1c000 and 1dfb0

Read W29EE011.BIN : The file read by TL866 before relfashing it with Bios
OLD.BIN : The file saved by awdflash during the 1st flash attempt
591PS025.BIN : The file that was supposed to be flashed
