How do I change the autostart screen icon for a drive?

[indigo0086]

Like a thumb drive. I want to change the icon that shows up in the screen that pops up when the autostart comes in, I have an autorun.inf file with these contents

[autorun] 
icon=GF.ico, 1
label=Indigo's Reliquary

but for the screen that shows (attached), on a tutorial I saw it for it had it's own icon, but how do I do it?

Also how do I change the type of files, because aside from the icon, I have no pictures on that drive.

My computer/right click the thumb drive /select properties/Autoplay/ select a content type. Not sure if you can add your own action to the list.

That just changes what to do for different format types, it doesn't necessarily change that type. I don't want to add actions, I want to change that general icon with my own, I've seen it done before.
