People say that: BootRom? A small chip embedded in Ethernet adapter. In a network , it is used to remotely boot local client computer without OS through server which has got the client OS. If your computer has an Ethernet adapter embedded with BootRom, but you boot it with the system installed, then the BootRom is an orphan. Why not give it a chance of life, and allow yourself a free SLIC? The BootRom is an independent module, it won't disable the Ethernet Card, nor ruin your computer, unlike BIOS modding, even if it fails to activate your system (mostly due to BIOS' SLIC functionality locked by system buildr, e.g. DELL). What do you think?
