All tools support, the main problem you need to connect the correct pins.

Hi Itried to connect wiring bios to
ezp2010 programmer. But bios wont detect. check the ine many times and lines are accurate.
Any clue?

Hi Finally I managed to remove the chip and programmed it . I could erase or write with medusa so i did it manually with EZP2010. I reprogramed the bios with 820-00244 MB91_0172_B00_no SN. But still stuck on apple logo at 99%

Origianlly I have replaced the CPU on this and after stuck on apple logo at99%. so i thought may be CPU recodnise code encrypted with bios. Any idea?
