- Network cards with model number 3c509 from 3Com, have been a very popular series. Many have Coyote Linux with such a network card built-in which could have been produced for example in 1989, almost 20 years ago. We've run these cards in three years with Coyote firewall without any problems. Once you have managed to get them running, they will probably run for a long time. But it is sometimes difficult to get the cards to work in the first place. This is because they have an ISA bus. This means that important addresses (IO) and termination messages (IRQ) must be handled manually. This is done automatically with PCI cards. But using one ISA card requires extra effort. IO and IRQ on these cards can be handled by an old DOS program. This can be somewhat difficult to obtain, since this is almost 20 years old software.

  The DOS configuration program is called `3c5x9cfg.exe`, and it is used in the following way:
  
   1. Start the machine with DOS. One can use !FreeDOS or a boot floppy created with Windows 95 or 98.
-  1. As soon as the machine is booted using DOS, insert a diskett with the program `3c5x9cfg.exe`. Run the program 3c5x9cfg.exe from the command line in DOS.
