You get an error during install and the readme file says backup drivers??
First if you get an error installing/playing the game with an error refering to the disc not readable or something, this means that either the disc is defective, or the crappy copy protection is preventing you from using the disc.
This has absulutely nothing todo with a firmware of your optical devices. (such as your nec) Blame the gaming company you bought it from.
/Edit: Ah update instead of backup makes already a bit more sense... but upgrading cdrom drivers????
THis cannot be done since they are part of the operating system, there are no loose cdrom drivers. The only driver that could possibly be updated are the IDE drivers. These are included by your mainboard chipset drivers. So update those if you wan't to update something. I however seriously doubt this will do any good.
