Ready for ec/kbc update. please the ec/kbc update diskette in the drive

there is no setting in bios for that
That will be an update in win 7 program and as win 7 is no longer supported , you may have to change to win 10 to get it

This is a keyboard error. Try pressing all the keys (make sure none are stuck). If this doesn't help you may need to try removing and reinstalling the keyboard (make sure the cable is inserted correctly) or you may need to replace your keyboard.

I don't see a problem with that as that is the old way of updating firmware.
Have you got a question? If so please post your question and we will help you solve it.

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.

A KBC error is an indication of a compatability issue. An input device, could be mouse or keyboard is having trouble talking with the system. Check to see if your system has a BIOS update. If possible, disconnect/remove the keybaord and/or mouse and replace with an external usb device and see if your problem still persists. Good luck. -Carlos:

plz visit Microsoft for the update

go to system setting by pressing F2 when you see the toshiba or bios logo

disable the system setting auto update.

Hold the "Esc"key when you power on the laptop until you get the BIOS setup screen coming up.

But I don't think you can fix the Ec/KEB problem by change any thing in BIOS or you just want find USB drive and make it boot-able from BIOs?

go to the bios and select your first booting device hard disk

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 the error, congratulations, you fixed a stuck [Tab] key. If you do see the error message, you should contact a Toshiba Authorized Service Provider and have the system serviced
