Will someone please explain what firmware is?
thank you

there are firmwares upgrades for dvd drives-If thats what your asking? I am not an expert on this but -I think there is a rom or memory chip which contains the firmware to tell the dvd drive what media and what speed to read or write. You can upgrade the firmware by going to the manfactures site. You have to be careful when applying firmwares.Do not have dvds or disks in the drive when upgrading firmware and follow the instructions or you can ruin the drive. Hope this helps explains what you want.

thank you scotton
