Whenever we plug in a new thumb drive, we get a pop-up saying
Installing Device Driver and then after sometime the autorun dialog pops-up.
So when installing another OS from bootable flash drive - how does the BIOS, which i suppose is very rudimentary compared to the OS itself, manage to quickly read data from flash drive (that too at the very begining of boot) without any need of installing device drivers.
Edit: I have noticed Linux (Ubuntu 12.04 in my case) also doesn't need to install the device driver & the drive automatically opens in Nautilus. How does this work?
