Hello everybody. I have an HP Pavilion zd7144EA Notebook PC which could not boot properly (It stucks on boot screen with HP logo). I have decided to flash its bios, so I have desoldered its EEPROM to program it using an EEPROM programmer (I have a Willem EPROM Programmer PCB50B). I have downloaded its BIOS file from this page: http://ftp.hp.com/pub/softpaq/sp28501-29000/sp28962.exe then have extracted it using 7-Zip, then have re-exctracted the extracted file WINPHLASHF34.exe using 7-Zip again. Inside, I have found 5 BIOS files (RYAN1F34.P31, RYAN1F34.P34, RYAN1F34.Q34, RYAN1F34.Q36 and RYAN1F34.R10). The question is which one should I use to flash the EEPROM !? Help me please. Thank you for your understanding.
