|Yeah, it'd probably be easier to pull the drive and put it in another computer. But you might try this:|
Boot up and use F8 and choose 'safe mode command prompt only' from the menu. Then at the c:\> prompt type scanreg/restore and enter. Choose a registry to restore from just before you installed the Iomega software.
Then reboot and see if you get to the normal desktop screen. If so, google iodrvf-w98-x86-403.exe. That's just the drivers; no other software crap. Download and run that file.
Also make sure in cmos/bios setup that the parallel port is configured as Enhanced Parallel Port or Bidirectional.
