oh i'm sorry i uploaded incorrect file. here is the correct one.

Now to the results.
flashed in the file and verified the flash went good. worked perfectly, went into FACTORY MODE.
but now to the odd thing:

While in factory mode, and entering the service tag, the computer dies randomly before I got to save the service tag, it just rebooted in the middle of entering it.
Tried again, went into factory mode, started entering service tag but it then died randomly again. (both times on DC power).

Now it just turns on, fans on full speed, caps lock LED on.
no beeps.
Display test (D key) works.

Tried reflashing the file again (I could see that the file does not match anymore, so the computer writes something to the BIOS).

Same result.

Verifying the BIOS chip shows that the content is again changed, so apparently it can boot the bootloader for the BIOS chip.


I guess there is some hardware fault on the computer, so any ideas what it could be?

Here is how the computer behaves:
On DC only: Computer reboots every like 30 seconds, fans full speed, caps lock LED on, screen black.
On battery only: Computer is stable, but screen is black all the time. Have had it on for like 15 minutes.
On DC + Battery - same as Battery only.

Tried both with BIOS battery attached and detached.

Any ideas what could be the problem?

Hey there.

Just wondering if you got it all sorted out ? I'm having a similar issue..
How did you go programming the 25B256 with the CH341a programmer ( i believe it was showing as a 25Q256 ) ? and did you program it on or off the board ?

Thx

No, this chip only holds 1MB of data. Read the post above.

I wasn't sure if changing code in two places was necessary, but it works very well, thank you

and sorry for the previous post, I wanted to write it in English but I didn't notice that Google Translator automatically changed my entry to Polish
