I need to boot from CD so I can rebuild a PC. Since I only have a USB keyboard, during boot the keyboard does not work because USB drivers are loaded from Windows. I need to be able to hit F12 so I can change the boot sequence. Please help.

Thanks

Sean

The solution is to connect your USB keyboard in to the front panel top USB connector and hey presto will will be able to continue using the USB keyboard when you arrive at the press enter to install windows, F3 to exit, etc screen.

The reason that the keyboard works up until the point of pressing enter to continue installing Windows is that the BIOS is handling the support for controlling the devices, when the "Windows is starting" message is displayed the control of the devices is being passed from the BIOS to Windows setup; in older systems you had the option to enable "Legacy USB support" which would effectivly tell the BIOS to leave it's microcode active for USB input device's, potientially allowing you to use a USB device with an OS that does not natively support USB i.e. DOS (basically what XP setup is using).
Dell removed this option from the BIOS with the Optiplex 740 and up (probably older modles as well) and instead set the BIOS microcode to only be active for the front USB connectors.
