I have created a custom Windows XP Embedded image for the Dell Mini 9. It is not perfect but it works. I am trying to make an Internet only OS, and make the Mini boot as quick as possible.
I timed startup between Windows 7 and XPe. This is from when the Power button is pressed (from a cold off state) to either the desktop or login screen. These include POST with a USB optical drive connected (this adds a few seconds).
XPe 19.7 to desktop
Windows 7 43.4 to log in screen
The XPe image is currently 320 MB, but I could make it smaller if I wanted. I plan on re-doing the image with EWF and HORM (this will make it boot even faster). HORM uses a resume state file to boot.
Is anyone here interested in XPe images? I mean it is not a typical OS to use, because you have to pay $1000 dollars for 1 licence and the toolkit to create the image and then like 100 per licence after that.
Anyway, If anyone is really interested in using it let me know I can provide you with the image and a licence. In fact have 7 valid licences for XPe I do not need. I will send you the COA sticker, and you NEED to stick it on the bottom of your MINI to be properly licenced.
