Windows 95 Installation Guide for FlexPort

Before Installing
Flexport installation is the easiest when you have a Windows 95 - Pentium system. Here's what you need to do first:
- Before you install the Flexport card in your system, you should go to the Control panel, click on the system icon and than go to the Device Manager, Computer Properties.
- You should write down all the IRQs that are not listed. Unlisted IRQs are those IRQs that are available.
- You should then go to the existing ports and click on properties and resources to find out the input/output range and interrupt used by that port.
- If you have an internal modem, find out what COM port it is using and its IRQ.
- Now that you have all the information, you can proceed to set the jumpers on the Flexport.
The Pentium system has two serial ports and a parallel port. These ports should have been setup as follows:
- COM1 3F8, IRQ 4
- COM2 2F8, IRQ 3
- LPT1, 378, IRQ 7
If a modem is internal, check its address and IRQ.

FlexPort 42 Set-Up
- PORT 1, COM3, IRQ (any available IRQ)
- PORT 2, COM4, IRQ (any available IRQ)
- PORT 3, COM5, IRQ (any available IRQ)
- PORT 4, COM6, IRQ (any available IRQ)
You may find that you do not have enough free IRQs, therefore, take a good look at the devices you want to connect to these ports. Group those ports as follows:
- Group 1 - Devices you know you will not operate at the same time (simultaneously) and that they are not bi-directional. ( such as dot matrix printer, label printer, tablets, laser printer, etc.)
- Group 2 - Devices such as modems, HP Colorjet and any thing that talks back to the computer.
- You can use one IRQ for those Group1 devices (you can share IRQ).
- The group 2 devices need their own IRQ so assign them their own IRQ.
- IRQ 15 most often is not used by the system, you can find out by checking the following: If you have only one hard disk and one CD-ROM, most likely you are only using the primary drive interface. Check to see if the ribbon cable services both the hard drive and CD-ROM. If it is, you can than use IRQ 15 for your ports.
- Finally, to setup COM Port addresses that are nonstandard (COM5 and higher), you need to first go to the ADD NEW HARDWARE section in the CONTROL PANEL.
- Add a port manually; do not use the Wizard. Follow instructions as Windows prompts you, add one port at a time and reboot.
- After you added all the ports, you should than go back to the Device Manager, click on the Ports and LPTs.
- Go to the new ports you just added, change the input/output range and interrupts by using BASIC CONFIGURATION 8.

Parallel Ports Set-Up
The same procedures apply for the parallel ports. Here are a few thoughts that may clear up some confusion regarding the LPT label. Naming of the LPTs most often causes confusion. You should know that the following rules apply:
- Address 3BC is normally LPT1
- Address 378 is normally LPT2
- Address 278 is normally LPT3
- When you only have two parallel ports in the system, LPT1 normally takes the 378 address and address 278 becomes LPT2.
- In Flexport 42, if you want to install 3 LPTs, you should set the first parallel port in the Flexport using address 3BC. Your parallel port in the Motherboard most likely took the address 378.
- In Flexport 22EX, you should set the parallel port in the system motherboard using address 3BC, and leave the default setting on the Flexport alone. You need to change the CMOS (BIOS) setting as well as Windows.
