Default [Q] boot.blob and vendor IDs?

Hi all,

I'm installing CM10.1 on a TF201. Extracting the shows there's a boot.blob and a boot.img. I've fastboot'd the boot.img, and can boot into CM fine.

What does the boot.blob provide, do I need to flash it, and if so, does the command need a -i 0x0b05 argument? I've seen other threads which state that the command should be:

fastboot flash boot -i 0x0b05 boot.blob
rather than just

fastboot flash boot boot.blob
