[SetupParams]
    UserExecute="%SystemDrive%\Install\XPlode.exe /xml:#SYSTEMDRIVE#\Install\Phase3.xml /log:#SYSTEMDRIVE#\Phase3.log"

[GUIRunOnce]       <-----  after reboot
    "%Systemdrive%\Install\XPlode.exe /xml:#XPLODE#\Phase4.xml /log:#SYSTEMDRIVE#\Phase4.log"

Should the # not be a % ?

I'm nog using this one:

[SetupParams]
    UserExecute="%SYSTEMDRIVE%\Program Files\XPlode\XPlode.exe /xml:%SYSTEMDRIVE%\Program Files\XPlode\XPlode.xml /log:%SYSTEMDRIVE%\Program Files\XPlode\XPlode.log"

Could that work ?

use "#" instead of "%" from outside XPlode.

Indeed, you can always use # instead. It keep you from having errors.

So in your winnt.sif, use "#", not "%".

Nopes!

It needn't total up to 5 GB.

All it needs is 10 boot folders (3 MB each), all of which after optimization would end up occupying just another 4 MB of space in addition to a single 350 MB (or nearly that much) I386 directory.

Where can I found info on this?

thanx

Maybe you are interested in this, here it is:

go here for the multi-boot guide.

Just remember that there's no need for making multiple PRO2/PRO3 etc. folders under the SETUP folder (the one where you have I386 directory). You just need to edit the txtsetup.sif in the PRO2/PRO3 etc. boot folders to link to your normal single I386 folder. Got it?

For any more info on discussing this, start a new thread - and PM me the link to it.
