For some reason the 39MB partition now has a letter assigned to i - previously it didn't, and the system called it the OEM partition.

I am now able to browse the partition. I have attached a screenshot of the contents of it.

Those are definitely Dell system files, but I don't see any boot files, so it doesn't took like it ever was the 100 MB "System Reserved" partition.

There should be no danger if you wish to remove the drive letter using the Drive Management Utility in Windows 7. It will prevent modifying the files, and you can always give it a drive letter again if needed.
