I have 90Gh/s Bitcoin Miner and its almost useless for Bitcoin Mining with current difficulty. By changing the Linux software installed in it can I convert this Bitcoin Miner to Litecoin Miner? I am capable on uninstalling/flashing the current operating system and re-install a new one but I am wondering is it just software that decides to mine only Bitcoin or hardware too supports only Bitcoin Mining?
If not possible with Litecoin Miner can I use this miner for mining any other crypto-currency?
No, you can't. And this has nothing to do with the operating system. Your hardware has a bitcoin ASIC chip made only for doing Sha-256 calculations. Litecoin uses the Scrypt algorithm. Sha-256 and Scrypt are not the same, so what you are suggesting is impossible.
You can mine other Sha-256 coins instead of Bitcoin.
Nope. If you want to be a bit more profitable, you could try a different sha256 coin. Any coin using the sha256 algo can be mined with your miner.
It is hardware bound. The above answer is correct. Another option is to rent out your hash-power and receive other cryptocoins.
