Hi, I am using GUI ming and I saw these in the FAQ section on GUI mining page :
 
Q: What extra flags do I use?
A: If you have a Radeon 5xxx card (for example 5770, 5890), use '-v -w128'. On CPU you don't need any flags. For other cards ask around.

but I have no idea where should I put these parameters. I read the README file and It said "entered in the Extra Flags field" and I don't get it.

Please help!

O!
thanks!

I couldn't see that......
