Every time I reboot, I get this cheerful black screen that tells me to Press to bypass LAN check. What can I do to get rid of this?
IDEAS and solutions are more than welcome and very much appreciated.
THANK youI guess the easiest way to get rid of it would be to press  

You didn't mention an OS. Is this little black screen a command or cmd window? Do you have if fact any LAN software installed on your machine?

Boot startup programs can be started from several places. Win9x boxes use the autoexec.bat file, the registry, and the startup folder. WinNT boxes use the autoexec.nt, the registry and startup folder.

Try running msconfig from the Windows Run BOX, click the startup tab, and look for something related to a LAN.  If you find something unclick it and OK your way out.

Also check your startup folder (START==>programs==>startup) and see if any entries relate to your LAN.

Also edit whichever autoexec file you have and again check for any entries related to a LAN.

If you do find something and remove it, you'll need to reboot to see if you got the correct item.

Hope this helps. 8-)

Note: Unfortunately msconfig does not report all the startups from the registry. You may have installed some software that installed the LAN item deep in the registry. There are 3rd party programs for discovering this stuff, but lets start with the obvious.This is a setting in your BIOS, check your BIOS.Hi
Unfortunately there are no entries related to LAN. I am not confident changing things in BIOS as I have had one to  many crashes over the last few years. Is there no software like Baseline or Secunia etc that I can run that will either fix the error or show me step by step what to do?
Thank you once again

PS Is there a really good free antispam that I can run with adware and Norton?
