There are many instances when an error may occur during the boot process, and a device is needed to display the POST Errors. Of course, POST Code Diagnostic Reader Cards (and onboard displays) are already available. However, these cards require that the user open the system and insert the Card into a PCI slot. This can be a time consuming and a somewhat tedious task (especially for Blade and Rack Mountable systems). A USB key-like device with a seven segment display could be designed to simplify this process. The device will be inserted into a USB port on a BladeCenter, and display the POST errors. Along with the physical device, special software will be needed to allow communication on the USB port at the appropriate time during the boot process.
