Chip pinout is same with standard DIP8/SOP8/SO8 SPI chips. Connector pinout is in attached picture.
But the best way is to desolder the chip, solder to programmer adapter DIP8, or use a "crocodile"-type adapter, reprogram chip using the SPI programmer, and then solder it back to MoBo. If You can't do this - better will be to try it in any serious IT service center.

It's not a some kind of test points, it's an in-system SPI programmer with special UEFI dump. Time for repairing UEFI PWD lock is same with total 64Mb SPI reprogramming time with new, good SPI programmer, based on CYPRESS MCU. I do this job not in 15 secs, but in 10 minutes. I use very old SPI programmer WILLEM2000 LPT. It works nice, and I don't want to change them.

unsolder you the chip or are you using this isp connector with your programmer?

I think to buy isp connector but for a reasonable price (if someone knows place to buy please share) this time i will try to find alternate points to solder on board or reomve chip with hotair. Posted after 1 hour 6 minutes 49 seconds: final pinout from boarview
