Another problem, or two. My ps2 keyboard had some non functioning keys, so I got a USB board, but now I can not get XP to recognize the USB keyboard on startup, in order to to get into safe mode. I was told there was another way, by running 'msconfig', and doing it from there, but when I try, I get yet another error message saying that Windows cannot find 'msconfig'. What!? Please, can you solve either? As always, any civil response is welcome.What operating system are you running?
What is the new keyboard?

Try plugging the new keyboard in whilst Windows is running.
How are you trying to find MSConfig? Through RUN or Command Prompt?Borrow a PS/2 keyboard. (The "other kind" of keyboard.) Nothing to do with PS2 games consoles, by the way.



There is a well known USB keyboard "gotcha" - namely that if "USB Legacy Support" is not enabled in the BIOS, you cannot press a key to get into the BIOS to enable it. (Sometimes it is sometimes called "Enable USB keyboard and mouse").

For your USB keyboard or mouse to work with MS-DOS-based utilities and non-Windows modes (such as before Windows has loaded, when you need to press F8 to ENTER safe mode), your computer must have USB Legacy Support enabled in the BIOS. USB Legacy Support allows the BIOS to interact with a USB keyboard, and in limited cases, a USB mouse.

If USB Legacy Support is DISABLED in the BIOS, you will not be able to use your USB mouse or keyboard in any of the following situations:

Running your computer in Safe mode.

Using a Windows Startup menu.

Starting your computer in MS-DOS mode (instead of opening a MS-DOS session from Windows).

Starting your computer from a floppy disk or leaving a floppy disk in the drive when you TURN on or restart your computer.

Windows "blue screen" errors that ask you to "Press any key to continue".

Responding to ScanDisk and other messages during the start-up sequence.

Editing or upgrading the BIOS.

Entering a BIOS password.

So....

Borrow PS/2 keyboard

Switch off computer

Plug in PS/2 keyboard

Unplug USB keyboard

Power up computer

Enter the BIOS setup

Set Enable USB legacy support

Save & exit BIOS setup

Start & shut down Windows

Switch off

Unplug PS/2 keyboard

Plug in USB keyboard

Give BACK PS/2 keyboard

From now on, you can enter safe mode with your USB keyboard.
I run XP. The keyboard was so cheap, it has no Brand. Straight from China. It was only to be a backup. It works, except for getting into safe mode. I tried to find MSConfig through 'RUN'. AS for now, I will follow Dias de veranos' advice. I will get back to you asap.I predict success...SUCCESS! Thanks guys.Congrats !
Everyone should have a PS2 keyboard...even if it sits in the closet most of the time.My laptop doesn't have a PS/2 port. I REALLY hate that.
