PC Trouble shooting: EC/ KBC update

I have read on a few websites that this is actually a problem with the tab key sticking in. By pressing the tab key when booting a toshiba notebook you invoke a driver update, which is why it will ask for the diskette after logging in to windows.
Clean you keyboard (you may need to take apart the notebook to do so), especially the tab key on the left hand side.

This can mean only one of two possible things. Either the [Tab] key on your computer is stuck, or your system needs to be serviced

First, turn the computer off. If the cause is a stuck [Tab] key, you may be able to un-stick it by tapping the [Tab] key several times. Turn the computer back on. If you don't see "Ready for EC/KBC update", congratulations, you fixed a stuck [Tab] key. If you do see the "Ready for EC/KBC update" message, you should contact a Toshiba Authorized Service Provider and have the system serviced

The Toshiba keyboards are bad about that. My wifes kept giving triple "E"s and I figured I'd clean it like in the old days. It didn't help the "E" problem but the rest of the keys worked better. I ended up getting her another keyboard.

I guess I misunderstood the idea behind this site. I am having the same problem. I was hoping I could find where to get the file or files to create an EC/KBC update disk. Being the age of these laptops there surely is no warranty issue left, so fix the problem ourselves would be the preffered method. If anyone has found this information or dealt with this problem before please respond with your solution! ;>
