    if the bios floppy flash did not work, then thats all you can do, this is because the board is AMD socket A (462) and is old, i would recommend that you get a board that will support USB boot option

    kind regards

Hello I want to boot Latitude D600 by external HDD (usb port) without internall HDD there are no selection for USB Boot in his BIOS help me please thank

If the USB port is not available in the BIOS start up boot sequence then it is not possible to boot up from an USB port on this notebook model.
In this case the USB port will only be activated when Windows starts up from the internal hard disk and the USB driver is running.

After inserting device in USB port, system went down and won't boot back up. Someone told me that it was probably the motherboard. Is there any possible solution other that replacing the motherboard?

I have seen it so many times where USB fries mother boards for no reason. Well one reason is plugging it in the wrong way but if it don't boot up most likely you have to replace the mother board.

Key board port is not working

Try another keyboard if at all possible. Port sill not working?
You can bypass the PS2 port for your key board. You'll need to buy a PS2 to USB Y cable. Places like Best Buy have them. Here is a picture of the cable;

On startup my keyboard doesn't work

Hello iko_gan,

This is actually a problem with USB Keyboards, Make sure that your BIOS is set to boot with USB making USB part of the boot sequence as opposed to an OS driver driven function, and if possible use the USB 1 port and not the USB 2 port. USB 2 is more suited for Hard drives. and why use all of your USB bandwidth for your key board.

This helped me solve my problem in this area.
