ACCEPTANCE test is usualy done by your customer but it used to defined the readiness level of product too, it checks the "requirement" doc which means functionality.
the books said that at least one test case should be provided for each requirement, which means that if you test IE at least it shoul find and display the html file.
i suggest that you choose the test cases which are related to functionality of majour features. now make the senario which is going through the features and test their functionality positively.
