whaaat ?
look forwar:
U21 - Main Bios
U9 - EC
U4 - EC serials
U8 - it's USB 3.0 но password reset here - u8 for usb 3.0 decoding
this chip have different size if you need main bios you must write a U21... not U8
Here is main bios for "E" revision not "3" correct rev. E (may be you write wrong digit)
