okay, i enabled the boot logging, tried to started in normal mode once (same as always) and then started the Mini XP.
i tried the search function for "ntbtlog" and looked manually in c:\windows, but that file does not exist. i expanded the search to the whole of C: but to no avail.
i found the ntoskrnl.exe file - quite a few actually - the sizes vary between 2,132 kb and 2,141 kb
same for ntkrnlpa.exe - sizes vary between 2,011 kb and 2,021 kb
Hard drive - SATA or IDE? i don't know, how can i find out?
