This is not going to be an easy one to give a one shot answer to.
To find the drivers you need to be able to use the card under DOS you need to go to the intel website and go to support, downloads and find your LAN adapter. Then select the downloads for DOS for your adapter. They do exist, I just looked. They should give you instructions for the files you will need to install and changes to make to your startup files (autoexec.bat and config.sys) files. If you can't boot into DOS from your hard drive, then you will have to transfer the driver and startup files to a bootable DOS floppy. You can make the boot floppy using the "format a: /s" command assuming your floppy is your a: drive. Then transfer the needed files to the floppy. You may also have to change references to c: to a: in the startup files you copy to the floppy.
Depending on the type of network you are trying to connect to you will have to follow different sets of instuctions for the setup of the LAN card. I would talk to whomever set your network up for guidance.
On a novell network once you are connected and logged in you should be able to use the "map" command to map a network drive on your machine to another machine/server on your network
On a microsoft network, hopefully you will be able to use the netbeui protocol (ask your LAN guy) you can use the "net start workstation" command to start the LAN. Then use, for example, "net use x: \\abc\s" to map the x: drive to the s share on computer ABC.
Once you have a drive mapped you can then copy your files to that network drive.
Hope this helps.
