Some parallel port mode settings may not allow your Iomega drive and computer to communicate properly. Because computer manufacturers have individualized and varying configurations within their systems, the best source for information regarding your parallel port mode settings is your computer owner's manual.

   1. Locate the parallel port mode setting in your computer Setup. The parallel port mode settings may be located in the Advanced Settings section, Peripherals, Communication or Input/Output sections.

   2. If the parallel port mode is set to ECP or unidirectional, change the setting to a different mode.

   3. Exit out of the computer setup, making sure you save the changes.

Compaq computers with Compaq BIOS (setup) will not allow you to change the parallel port settings. You must disable the DMA channel, which will cause the parallel port to change to EPP mode. Turn off the DMA channel assigned to the port and use the same hardware configuration that the current port is assigned. This will change the mode from ECP to EPP.

Example: Change 0378-037F, IRQ 7 DMA2 to: 0378-037f, IRQ7.

Note: On some older Compaq computers, it may not be possible to assign the parallel port settings without a DMA setting. If this is the case, contact Compaq for a possible BIOS upgrade.
