My screen shows ' keyboard error or no keyboard present'.... I reset CMOS to default... no help... if I buy a USB keyboard, will USB Legacy still be enabled after defaulting???? THANKS!!!!!!!! ...

Buying a USB keyboard will be the same as using the PS/2 (the round one with the 6 pins), and USB legacy should be enabled by default.
If not, you could still enable it in the BIOS.

I have toshiba dyna notebook ss 2000m. My windows xp corupted by a virus. all .dll files became .exe files. now i want to install a fresh copy of win-xp. but when i can't be able to boot from a usb...

There are two possible reasons why, First, maybe the legacy onboard usb is not enable from the BIOS. I believe that you know how to check it, just look for the legacy USB or legacy onboard.

Second, it is possible that your windows XP disc is not a bottable version, meaning the disc will be read as a data cd only and not an installer.

But try to check for the first, that is closer to resolve your problem.

My amd athlon 64 windows vista computor will not reconize player

First, try connecting the player into another computer just to make sure that there's no problem with the player.

Now, if the problem is isolated with Windows Vista, all you have to do is to update the USB driver of your computer or enable the USB Legacy Support and the problem should be resolved.

By the way, you need to contact the computer manufacturer to assist you in enabling the USB Legacy Support.

Have a great day!

USB keyboard problems.

Since you have tried using another USB keyboard but you got the same problem, then the issue has something to do with the USB.

Contact the manufacturer and have them enable the USB Legacy Support of your computer. This should resolve the issue. If they say that the USB Legacy Support is already enabled, then have them do something on your PC. It's obvious that your PC is not working correctly with any USB keyboards.

Thank you!

My System Windows Xp Cannot read Usb thumb drive

If you insert it on a USB located on motherboard there usually should not be problems, only if you forget to enable in BIOS, USB 2.0 or USB legacy support. If you have a card reader installed, please verify the pin connection required. You can find it in your motherboard manul. USB Legacy is generally required if you want to boot from some USB device and not all motherboards require that to be enabled to recognize and boot from USB devices.

Dell optiplex wont boot up

If you are using a USB keyboard, then check in the bios that USB keyboard is enabled, and also Legacy support as well.
Legacy support will allow a USB keyboard to operate under the DOS environment.
This should allow you to press the any key to start booting from CD.
Hope that helps =)

That particular board has PS2 ports on it. I would suggest a couple of things. If you have a PS2 keyboard, plug it in and use it since legacy USB support might not be turned on in BIOS.

If that works, go into BIOS and turn on legacy USB support and then try the USB KB again.

Secondly, if you don't have a PS2 keyboard, get your manual out and clear the CMOS. It might be that the legacy USB is turned off and clearing the CMOS will re-enable that (assuming it is done at the factory).

Good luch.
