INSTALLATION PROCEDURE FOR PARALLEL-EPP/ECP IN WINDOWS NT4.0 1) Boot into NT without the Parallel-ECP/EPP installed in the computer. 2) Check for available IRQs. Go to Start Programs Administrative Tools Windows NT Diagnostics and enter the Resources Tab. Check for a free IRQ in here. NT does not show the IRQ for parallel ports. By default the motherboard Parallel Port uses IRQ7, so assume IRQ7 is not free. Find a number missing in here between 0 and 15. If 9 is missing then set the IRQ jumper to 2. If all the IRQs are being used then you must install our card without an IRQ. 3) Remove the DMA jumpers. NT4.0 does not support ECP. ECP mode is enabled by enabling a DMA channel. 3) Find out which Input/Output Address the OnBoard parallel port is using. Go to Start Programs Administrative Tools Windows NT Diagnostics and enter the Resources Tab and then Click the Devices button. Double-click the ParPort device. This shows your existing parallel port addresses. Do not set the card to any of these addresses. Set the card to the next address. For example: on Lava Card LPT1=3bc LPT2=378 LPT3=278 note NT4.0 cannot detect the non-standard addresses (LPT4 and up) so do not choose one of those addresses. If you see 378 then set the Lava Card to LPT3 278 to make it LPT2. 5)Shut down and put the card in the ISA slot. 6) Boot back into NT and verify that our card has installed. Go to Start Programs Administrative Tools Windows NT Diagnostics and enter the Resources Tab and then Click the Devices button. Double-click the ParPort device. If you see an additional set of input/output ranges then you have successfully installed our card.
