How to boot from HIBERNATION permanently?

[borgy246]

I use FirstDefense-ISR to dual-boot different winxp-images suited especially for the tasks im about to do (to get the most effect and battery capacity i truelly can out of my laptop)

I have for example one really stripped down image (for surfing) wich also is "freezed" (resets completely after each use...nice to have when surfing all sorts of different sites, and because of the freezing I don't need layered defense (which really can use a bit of processing power, kbits of mem and battery)

Then...it would be awesome if I could get to start a hibernated image every time... but how to do it?

Does anyone know precisely what the hibernation really changes in files or registry? What tells the startup-process to load the memory-image from the hibernate-file on root?

The hibernate functionality actually uses the ACPI BIOS to boot, and writes a bit of data to the BIOS and syncs with the real-time clock to make this work. It does set some registry entries as well, and I don't know if the bit written to the BIOS is necessary - however, that particular bit of Windows data isn't public, so it's probably going to have to be trial and error, and perhaps system snapshots before and after and some boot information via filemon and regmon that'll get you to where you want to go, if it's even possible.
