if the ibook is stalling on startup until the control strip loads you can try this:
delete the Servers folder in the System Folder and restart and rebuild your desktop.
delete the invisible file 'AppleShare PDS' and restart...
deleted the AppleShare Prep file (go Sherlock or look in prefs)
try the last one first and see if that works. This same problem happens to me with my powerbook 2000, it can sometimes take 3+ min to start up.
