I have an ibm computer that was recently formatted. Since the formatt I have not been able to get it online, I am in need or ethernet drivers for rev:1.5 motherboard

You will have to open up your network connections click start control panel network connections this may vary depending on your operating system look for local area connection if you see a red x or a yellow exclamation or question mark ! ? you will need to update or install the driver or it could be firewalled
If you are trying to connect through a modem/router you it should have come with a disk then
you might have to connect the usb lead to your modem to get a connection then
click start control panel administrive tools computer management device manager scroll to network adapters should see a yellow question mark? right click install drivers
the driver might be on the disc supplied by your ISP internet service provider
or the motherboard disc
