Just because you got a MAC address doesn’t mean it worked, or that it is even talking to an Ethernet card.
Those should match in the manufacturer database. But performance is not as good as with the first approach and the “one size fits all” philosophy 3x509b to some design compromises that may not be good for the individual programs.
Here is my set of criteria:. Why on Earth would anybody want to do that? Does it use protected mode? It will run with a NEC V20 and it might be possible to recompile it to get rid of the specific instructions. They switched to a packet driver interface when the variety of Ethernet cards mushroomed.
Serial ports supported “hot plugging” removing 3c5009b connecting devices while running while parallel ports did not, so swapping devices on a parallel port often required shutting the computer and the devices off. For machines without slots or where you want a temporary solution I would use a parallel-port to Ethernet adapter.
This probably been discussed many times, the 3cB will work in a 8-bit ISA slot however the driver require The packet driver for an adapter is effectively the device driver for the adapter. This was a simple approach that worked back when there were few network adapters, but you can see a few problems with it.

The time now is DOS has been an obsolete operating system for close to twenty years but it still shows up in a few places:.
Application software would use the API to send and receive packets.
All 3c509v the code is 16 bit and most of the programs will run on a K system using DOS 2. If people had any sort of connectivity it might have been to use a bulletin board system BBS through a dial-up modem or to talk to a Novell Netware server running on their local network.
When the packet driver loads it is going to look for the Ethernet adapter and try to communicate with it to 3c5009b that the Ethernet adapter is available.
As a result, there was a great variety of programs that used different rules for sending data. Stated requirements are DOS 2.
It connects to the machine using the parallel port and the packet driver makes it look just like a real Ethernet adapter. Blasting files around the house at speeds ranging from 25KB per second on a slow machine with a parallel-port Ethernet adapter to KB per second on a high end packey a 16 bit NE compatible adapter sure beats the heck out of ‘sneakernet.
Most of my experience has been with packet drivers and related software; a list of additional resources is provided to help you understand packet driver based solutions and other solutions that I mentioned earlier. Of course you might have a machine new enough to have PCI slots or an Ethernet adapter on the motherboard. Often there was just one parallel port compared with two serial ports on a computer, and the parallel port was often connected to a printer.
That 3c509bb might be a network adapter, an Ethernet chipset connected through the parallel port, or even just a plain serial port.
Here are some examples:. At this point your machine is physically ready to talk on your network. If you can’t find a sticker on the card with the MAC address then the MAC address reported by the packet driver should at least match the range assigned to the manufacturer of the card.
Inside the packet driver is code to talk to a specific piece of hardware.
