Answer 1

You can't use an autorun.ini with a removable storage device (eg USB drive), due to Windows XP protections against these devices.

Here is the Microsoft advice on the subject:

Q: What must I do to trigger Autorun on my USB storage device?

The Autorun capabilities are restricted to CD-ROM drives and fixed disk drives. If you need to make a USB storage device perform Autorun,
- the device must not be marked as a removable media device
and
- the device must contain an Autorun.inf file and a startup application.

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.

For more information about the SCSI Inquiry command, see the T10 committee located at http://www.t10.org.

For more information about the StorageDeviceProperty, see the STORAGE_DEVICE_DESCRIPTOR storage structure in the Windows DDK, located at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/storage_r/hh/storage_r/structs-general_3c393126-f5c8-47d8-bfb5-6127ce656e9a.xml.asp.

For more information on Autorun.inf files see the "Creating an AutoRun-Enabled Application" article located at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/programmersguide/shell_basics/shell_basics_extending/autorun/autoplay_works.asp?frame=true.

Well, not sure about this but will give it a try:

If you want to boot from a USB drive, then you need a Mb that supports it. In that case, the USB device is still not using CDFS so I don't think that gets you what you need.

You could try writing an autoplay.ini file to run whatever you want to off the USB device when it is plugged in, so in effect it behaves the same way a CD does when you insert it - that is, "it starts by itself".

Another option would be to create an ISO image of whatever CD you want, and then move the ISO to the USB drive. then using a program like Daemon tools, mount the .iso as a virtual drive. Problem with that one is that it will only work on that USB port, on that machine, with your CD/DVD emulator running.

Does that help?
