usb-stick make it autorun

[KryptoS]

is it possible to make my usb-stick autorun? I know it goes with autorun.inf. But it's still puts up an dialog box where I have to chose between: running the program, browsing the stick, ...
But I want it like an cd, where the install program launches without interaction.
I read somewhere that the stick has to be marketed as 'non removable'. How can I do that? It's something with the firmware? Are there tools for?

after some searching I found this:

The removable media device setting is a flag contained within the SCSI Inquiry Data response to the SCSI Inquiry command. Bit 7 of byte 1 (indexed from 0) is the Removable Media Bit (RMB). A RMB set to zero indicates that the device is not a removable media device. A RMB of one indicates that the device is a removable media device. Drivers obtain this information by using the StorageDeviceProperty request.


So I need to change the RMB of my usb-stick. is this possible?
