Driver for the Accton EN1207D-TX4 PCI NIC used in lots of different pc's including the Packard Bell "PB BUSINESS 766 C, P/N : P350200201"
Unzip to a temp folder then get 2 1.44 mb floppy disks formatted and read for writing.
There will be 2 exe files in your temp folder:
1: 1207ddrv.exe (driver file)
2: Accton.exe (Setup, configuration and diagnose utility)
When you launch the exe file(s), data will be written to each floppy disk. Mark the first disk "Drivers" and mark the 2nd disk "Configure-Diagnose".
Then use those disks to install and configure the card.
Here's a photo of the NIC:
