# Setting up BFGMiner with Devices

(Asked by: username_0 on 2013-11-22)

I have a Dell Poweredge Server R200 set up with BFGMiner. Now I know this is old and not very powerful, but I am curious as to how I should use BFGMiner.

When I ran it initially, it was not able to find any devices (unless I am doing something wrong). I have an Advanced Micro Devices [AMD] nee ATI ES1000 VGA compatible controller but I dont know how to use this or the CPU for BFGMiner.

If you wish to keep with the same hardware, I suspect you'll get more money out of vanity-address mining than to mine bitcoins directly. Even then it might not be very efficient.

Vanity-address mining is like the equivalent of having a personalised number plate on your car; it involves hunting the bitcoin address space for a public address that starts with a short string (up to 8/9 characters is reasonable with some effort) someone chose, and with the right algorithm can be done securely so you never know the final private key in use.

It cannot be done with ASICs at present (AFAIK), but can be done using GPUs so the relative value is higher per hash-checked; though it does a quite-different operation so the very-specific ASICs aren't built to find the addresses.
