At work, all our PCs are loaded from a standard image (only modified slightly to cope with different hardware specs).
I need to change the boot.ini file to include the /3GB switch ... I found on some machines it worked, and on other machines it didn't* - even though the machine hardware/software is supposed to be identical.
* i.e. the machine failed to boot - it got to the stage where you are prompted which OS to load (i.e. the list of OS given in the boot.ini file), but then when selecting the OS with the 3GB switch it went straight to an error screen where only choice was to boot into Safe Mode, etc. (none of these choices worked - it consistently failed to boot).
Can anyone suggest why the 3GB switch might cause such behaviour?
