Bravo for the hard work ! It really sounds like you have managed to make many people's dream come true !!
Quite some time ago, I tried myself to boot a full XP from USB, without success
![:thumbsup:](http://reboot.pro/public/style_emoticons/default/thumbsup.gif)
My method was also based on WinVBlock rather than FiraDisk, but apparently there was (at the time) a limitation of WinVBlock which prevented booting from USB (it was working fine from HDD). See Shao's explanation here http://reboot.pro/11...post__p__102058).
I'm afraid I'm not as experienced or knowledgeable as you guys... Could you try to explain me, with as little jargon as possible, in which way this method is different from Wimb's (IMX_XP), or the variant I proposed (based on IMX_XP too, but with WinVBlock, and booting from a file backed-disk instead of RAM) ? Obviously there is nothing better than going through the steps one by one, but I'm lacking a bit of time and I would just like to get the bigger picture for now.
Many thank! Cheers,David.
