Add the frameBorder attribute (note the capital ‘B’).
So it would look like:
<iframe src="myURL" width="300" height="300" frameBorder="0">Browser not compatible.</iframe>
No. The HTML 5 spec mentions:
The method and formmethod content attributes are enumerated attributes
with the following keywords and states:
The keyword get, mapping to the state GET, indicating the HTTP GET
method. The GET method should only request and retrieve data and
should have no other effect.
The keyword post, mapping to the state
POST, indicating the HTTP POST method. The POST method requests that
the server accept the submitted form's data to be processed, which may
result in an item being added to a database, the creation of a new web
page resource, the updating of the existing page, or all of the
mentioned outcomes.
The keyword dialog, mapping to the state dialog, indicating that
submitting the form is intended to close the dialog box in which the
form finds itself, if any, and otherwise not submit.
The invalid value default for these attributes is the GET state
I.e. HTML forms only support GET and POST as HTTP request methods. A workaround for this is to tunnel other methods through POST by using a hidden form field which is read by the server and the request dispatched accordingly.
However, GET, POST, PUT and DELETE are supported by the implementations of XMLHttpRequest (i.e. AJAX calls) in all the major web browsers (IE, Firefox, Safari, Chrome, Opera).

You can download one of the Internet Explorer Application Compatibility VPC Images. These will work with Virtual PC (also a free download). The images available (at this time) are:
Note that these are time bombed and if you choose to use this solution you will need to download versions with the expiry date extended at some point. Presumably one day Microsoft will cease to offer the images for the older OSs as well.
