This is why I prefer to use a clip to extract the data rather than to desolder the IC! The ones that you get typically with a CH341 are rubbish, but the ones with spring-loaded needles that you can get quite cheaply on AliExpress work for me everytime! The only challenge is that you have to hold it in place with one hand whilst controlling your programmer software just with the other!

Yes, I've successfully used it several times before. If there is more than one BIOS chip and it doesn't find the correct pattern in first one it's always found it in another. This time, though, it doesn't finds it in either - and as far as I can tell they're the only two BIOS chips in the system....

Hi,

I have a Dell Latitude 5500 (Service Tag JH83733, motherboard LA-G901P) which is locked with an -8FC8 BIOS password.

I have successfully read and verified the contents of both the 8 and 16 MB BIOS chips (attached).

Normally I would unlock this myself with the Rex98 Patcher, but with both of these files it says '8FC8 Hex Pattern not Found'.

Can someone please explain what I might be doing wrong, or unlock the files for me? Thanks!...
