THX, but i dont can startup windows.

After i test the Bios Update CD from Lenovo, i have a startup PW.
I remove the cmos battery but i cant start the Laptop.

I can only Dump the Bios with Programmer and Clip and uploaded here.

Ok cant read the chip with my programmer NXP P24S08 :-(

Yes You need an HW SPI Programmer and a Pomona Soic Clip to read the
Eeprom Chip (usualy SPI 25 type) !
So read the Full Dump Firmware and upload It here and I will rebuild removing
SVP !!!

Hmm my Programmer can read spi 25.

Iám so [censored] noob

The PCA24S08 is intended to be pin compatible with standard 24C08 serial EEPROM.

And i search in my Software for 24S08 and found nothing.

Hmm with my Programmer i cant read the Chip, i test all Brands. Cant read. Can i buy a pre programmed Chip for the Laptop?
