The following steps are preliminary Windows 95/98© and Windows Millenium© Setup Steps and should be done before installing EDS or ENS into a computer. The EDS3 and EDS IV or EDS3 with ENS settings follow these preliminary steps. These steps will help to determine the best settings for a Melco Network PCB in a particular computer, and then reserve these settings so the Plug and Play feature of Windows cannot interfere with them.

1. Click on Start, Settings, Control panel, double click System, and click Device Manager tab
2. Click the Properties button below and you will see a list of IRQ's currently in use
3. Look for the numbers missing from the list and write them down for IRQ
4. Click on the Direct memory access (DMA) button above
5. Look for 00, 01, and 03 under setting and write down the ones not on the list for DMA
6. Click on the Reserve Resources tab above and click Add
7. Select a number between 3 and 15 that was noted in step 3 and type it in for IRQ. Click OK
8. The number you typed in will appear under setting
9. Click on the Direct memory access (DMA) button above and click Add
10. Select a number that was written down in step 5 and type it in for DMA. Click OK
11. The number you typed in will appear under setting
12. Click on the Input/output (I/O) button and click Add
13. Type in 03e0 for the start value and 03e7 for the end value and click OK. (NOTE:If the Melco Network PCB is already installed in the computer, it may display a Resource Conflict Warning error, click OK, the conflict it is seeing is normally with the Melco Network PCB. The I/O Address is the only resource used by the Melco Network Board that Windows will detect. If the Melco Network PCB. is not installed, and a Resource Conflict Warning error is displayed, answer OK, do it anyway. This will force the Plug and Play device using this address to use another, freeing up 03e0. This is a vary rare occurrence as address 03e0 is normally available in most computers)
14. Click OK on the computer properties window. If Windows asks to quit and restart, click NO
15. Click OK or Close on the Device Manager window
16. Close the control panel

 

Software settings for EDS3 users without ENS:

1. Click Start, Programs, Melco Apps, Config. Then click on the Hardware button
2. Under Network, select the IRQ that was selected in step 7 and enter it for IRQ
3. Under Network, select the DMA that was selected in step 10 and enter it for DMA
4. Under Network, select the I/O start address from step 13 and enter it for I/O Base
5. Click OK to save and exit EDS3 Advanced Configuration Options
6. Click OK to save and exit EDS3 Hardware Configuration

 

The settings in EDS3 Hardware Advanced Configuration Settings should look similar to the illustration below.

 

Software settings for EDSIV/EDSIII users with ENS:

1. Start ENS, Click on START/Programs/Melco Apps/ENS
2. Open the Properties Window. Click on TOOLS/Properties
3. Set the IRQ to the setting selected in step 7 above
4. Set the DMA to the setting selected in step 10 above
5. Set the I/O to the setting selected in step 13 above
6. Click on Apply, and then click on OK to close the Properties window

 

Settings for Properties in ENS should look similar to the picture below.

 

The next step is to configure and install the Melco network card to match the software settings.

1. Shut down and turn off the computer and remove the case off of the computer
2. Discharge any static charge in your body by touching a non-painted area of the computer frame
3. Remove the screw that holds the Melco network board in place and remove the network board. If installing for the first time, locate an empty ISA expansion slot and remove the blank plate for the slot
4. Set the IRQ jumper to the IRQ set in step 7 above
5. Set the DMA jumpers ( DREQ and DACK ) to the DMA set in step 10 above
6. Set the I/O base Jumpers ( JP1 ) to the I/O base set in step 13 above. There are three jumpers for the I/O base setting. Address 3e0 is the default setting ( jumpers 2,1,0 ON ) and can be left alone if this is the address to be used
7. Install the Melco network board into the computer and secure it with a holding screw
8. You are now finished configuring the Melco network board but it is recommended that you check to see that EDS3 is communicating with the peripheral(s) before the computer case is re-installed. Further servicing may be required. If you are not able to establish communication to the peripheral(s), there may be a conflict in the computer CMOS setup if your computer mother board is Plug and Play compatible (most Pentium computers are). To determine if your mother board is Plug and Play compatible, consult the computer manual or contact your computer vendor. If your computer IS Plug and Play compatible, you must reserve your network board IRQ and DMA settings for a Legacy ISA board (in CMOS) usually under PnP/PCI config depending on the computer. For further information, see the NOTE at the bottom of this procedure.

Melco Network PCB Jumper Locations

The I/O base jumpers (JP1 with numbers 2, 1, and 0 above each jumper) are located above the IRQ jumper.

There is a small switch between two of the RJ-45 peripheral jacks (J2 and J3) labeled S1. This switch is labeled with the words MELCO and STAR printed on the PCB. This switch MUST be switched to the MELCO side.

The peripheral cable needs to be plugged into either J1 or J2 (the jacks that are close together). The peripheral will NOT come on-line if it is plugged into the J3 jack (the J3 jack is separated from the other J1 and J2 jacks).

NOTE:The settings (IRQ and DMA) that are reserved in the Windows Device Manager must also be reserved in CMOS on Pentium computers. With most computers, this is done by pressing the delete key when prompted shortly after the computer power is turned on. Once in CMOS, select PnP or PCI config. If RESOURCES CONTROLLED BY is set to AUTO, change it to MANUAL using PageUp or PageDown keys. Then set the IRQ and DMA setting for the network card from PnP to LEGACY ISA using PageUp or PageDown keys. Consult the computer or mother board manual (or computer vendor) if further help is needed with the CMOS setup.
