They are two different things. There ARE DVI-A/I>HDMI and DVD-D>HDMI adapters..
Since DVI-A isn't compatible in any way with HDMI you would need an adapter that processed the data (expensive and probably low quality). DVI-D and HDMI is basically the same thing so you only need to rearrange the pins.
DVI-I is of course both DVI-A and DVI-D, so it can easily be converted to HDMI if it's used with DVI-D.http://en.wikipedia.org/wiki/Hdmi
The HDMI Specification has expanded to include three connectors, each intended for different markets.
The standard Type A HDMI connector has 19 pins, with bandwidth to support all SDTV, EDTV and HDTV modes and more. The plug outside dimensions are 13.9 mm wide by 4.45 mm high. Type A is electrically compatible with single-link DVI-D.
A higher resolution version called Type B is defined in HDMI 1.0. Type B has 29 pins (21.2 mm wide), allowing it to carry an expanded video channel for use with very high-resolution future displays, such as WQSXGA (3200x2048). Type B is electrically compatible with dual-link DVI-D, but is not in general use.
The Type C mini-connector is intended for portable devices. It is smaller than Type A (10.42 mm by 2.42 mm) but has the same 19-pin configuration.
So, a type B HDMI would support dual-link DVI.
However, as mentioned the use is limited. Very few TVs do support a resolution higher than 1920x1080p and that resolution can be achieved with Single Link DVI/HDMI-Type-A.
Correct me if I'm wrong but my understanding is that TVs and monitors featuring 1920x1080p/1920x1200 doesn't even support Dual Link - even though the original specs didn't support 1920x1080p.
So even if you were to use Dual Link DVI to a Type B HDMI adapter you would only be using "one link" anyway so you wouldn't gain anything at all - for TVs supporting 1080p or lower.
