3C509 DOS DRIVER

This page barely scratches the surface of DOS networking. Here are some examples:. This site hosts no abandonware. It also saves you time. But performance is not as good as with the first approach and the “one size fits all” philosophy leads to some design compromises that may not be good for the individual programs. Do you have one or are you running the DX4 at 5v? But if you enable networking you get the following advantages:.

For 8 bit ISA bus machines your choices are more limited. Parallel ports were not used for communications as much as serial ports were. This isn’t the only silver-faced beauty I own, either.

As a result, networking applications generally included code to talk to a few specific models of network adapters directly. When the packet driver loads it is going to look for the Ethernet adapter and try to communicate with it to ensure that the Ethernet adapter is available.

In this case, talk to a piece of networking hardware.

I’ll try it as soon as I get home! Even the slowest DOS machines dating back to the early s can do the following once networked:. But the overhead of the parallel port does hurt performance, so while it is a good basic solution it will never beat the performance of an Ethernet adapter on a card.

I would stick to classic Ethernet over these two alternatives – they tend to drop a lot of packets. Not sure on VRAM amount. After the packet driver is installed, other software will use the packet driver by setting parameters and issuing the software interrupt. Stated requirements are DOS 2.

This is usually in lieu of transferring the information over a computer network. A notable exception was LapLink by Traveling Software.

The software allowed the computers to doa files back and forth. Users browsing this forum: But performance is not as good as with the first approach and the “one size fits all” philosophy leads to some design compromises that may not be good for the individual programs. This disclaimer is brought to you thanks to the BSA.

This was a simple approach that worked back when there were few network adapters, but you can see a few problems with it. The good news is that networking adapters and equipment is as inexpensive as 3c50 will ever get, and most machines running DOS can easily make use of used equipment that people are just throwing away.

3c5099 are lots of factors that go into choosing networking hardware. And although DOS came a little bit before the era of widespread networking on home computers, there was enough overlap such that reasonably good networking software exists for DOS.

Anyway, I am sure some folks are curious to the system itself, so here are some pictures. Networking started to become more popular as businesses obtained multiple computers and they needed a way to communicate. That hardware might be a network adapter, an Ethernet chipset connected through the dso port, or even just a plain serial port.

There dso a lot of software out there for networking using a packet driver and there are already a lot of resources on the Internet that describe those resources.

The name is a tongue-in-cheek sound-alike to Ethernet, and refers to the use of someone wearing sneakers as the transport mechanism for the data.

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 with a 16 bit NE compatible adapter sure beats the heck out of ‘sneakernet.

There are lots of ways to connect computers together. An 8-bit Western Digital WD Ethernet card from is very different from a NE clone in a PC, yet the packet drivers for each card make them look the same to the rest of the system. Here are some notes on the ones that I have tried. A full implementation requires more memory than is usually available on an old PC.

A packet driver makes the hardware and network accessible in an easy manner. Back when DOS was a current operating system many machines were not network connected at all.

Brutman, mbbrutman at gmail. It talks to the packet driver for that hardware, and as far as the networking software is concerned all packet drivers all look and behave the same way.
