原文如下：
Extract dynamic VHD to RAM

Loading from dynamic VHD can be faster than loading from raw disk image when there is large unused space that has not been expanded.

I added dynamic VHD reading capability to this modified grub4dos.
You can use with map --mem.
It will reads content of disk image in dynamic VHD.
Don't map dynamic VHD directly without --mem.

Differencing VHD is not supported.
