1. shut down the computer, unplug its power cord, and remove the cover.

    2. if your order does not include the boot rom option, go ahead to step 3. if your order includes the boot rom option, then install the boot rom chip by plugging the chip into the boot rom socket on the dfe-550tx card. the notched end of the boot rom chip must be aligned with the notched end of the boot rom socket. opposite alignment will destroy the boot rom chip!

    3. firmly insert the contact edge of the dfe-550tx card into any available pci bus expansion slot.

    4. install the bracket screw to secure the card to the computer chassis.

    5. at this point, refer to section connecting the wol cable to install the wol cable between the nic and the pc motherboard.

    6. replace the computer cover.

    7. reconnect the computer power cord, and switch the computer power on. if the bios section of your computer boot program is plug and play compliant, then at power-up the bios will automatically configure itself for the newly installed dfe-550tx adapter.

    due to a fault in some plug-n-play bios programs, it happens occasionally that a newly installed adapter is assigned an irq number which is already assigned to another device. in such a case, the conflicting irq numbers (irq numbers must be unique) will cause faults in the behavior of both devices. if this happens, it is necessary to run the cmos setup utility, and manually assign a nonconflicting interrupt number to the dfe-550tx.
