Backing up nec3500 firmware first

vbimport

#1

is it possible for me to backup my firmware or eprom first? just like with the liteon utility to backup the eprom first…

You can backup your existing nec f/w easily with either binflash windows gui or NEC 3x00A Flasher through dos. Please correct me if I am wrong but I don’t think there is an eeprom backup utility as yet for the NEC drives. :slight_smile:

There’s no need for such a utility as there is no seperate EEPROM - at least none that I am aware of. The Flash ROM roughly consists of three parts:

  1. A safe mode firmware. Used for flashing and after misflashing your drive
  2. Calibration data / Settings. Used for drive adjustments, serial number, RPC settings, booktype settings
  3. The real firmware. That’s what you usually change.

Thanks for the clarification Liggy. :slight_smile:

i see…so does that means there is no need to backup any existing stock configurations on my nec nd-3500a? i planned to flash into a better firmware coz i can’t burn more than 2.4x on my POMSI002 dvd+r and i think i get crappy burns due to this… using stock firmware 2fc
