I think I did use loadide reset; exerpt from the manual:
It is possible to install IDEfix reset resident, too. To do so, insert
LoadIDE reset quiet in your startup-sequence. If you have trouble making
IDEfix reset resident, try LoadIDE 4k reset quiet. If this still doesn’t
work, try LoadIDE chip reset quiet.
Last but not least you may start IDEfix immediately but make it reset
resident, too. In this case, you must type LoadIDE start quiet.
