What is IMAGE_SDI turned on for ?
For supporting of booting from sdi format fiiles ?
If there is so, is it possible to boot, for example Windows installation WITHOUT wimboot using at all ?
There is boot.sdi file, by the way.

Introduction of SDI was in commit https://git.ipxe.org/ipxe.git/commitdiff...9bccd8e058 which also contains relevant description.

If you populate the sdi filesystem with all the data it might be possible, however that will probably be larger than the wim.
the normal boot.sdi we can find for win vista and later is just a minimal clean memory filesystem that the .wim is then virtually extracted on.

The linked http://msdn.microsoft.com/en-us/library/ms838543.aspx seems to be relevant.
Just to be clear, don't expect to be able to use this with anything other than Win XP SP1,2,3

But if you play with it, let us know what you find.
