An apparatus and method are described for identifying uncommitted memory in a system RAM during an initialization process of a computer system, such as a boot procedure or power-on self test, during which memory management is uncontrolled. In various embodiments of the invention, repeating patterns that are indicative of uncommitted memory blocks are identified within a conventional memory area of the system RAM. At least some of the uncommitted memory blocks are allocated for use by an option ROM or other BIOS data and a table is created identifying these uncommitted memory blocks. After the BIOS code exits the system RAM, the table is used to restore the uncommitted memory blocks into their previous data states.

A method 20 and computer apparatus for using available firmware flash ROM space as a diagnostic drive. The computer apparatus has a nonvolatile random access memory, an Extensible Firmware Interface (EFI) and a basic input and output system (BIOS). To implement the functionality provided by the present invention, a command shell of the EFI is modified to include the EFI driver and operates to configure available flash space normally reserved for firmware (BIOS) as a diagnostic disk drive. The modified EFI and the EFI driver are stored in the flash memory. When the computer system 10 is initialized (booted), the EFI driver configures the available space in the flash memory that is not allocated to the firmware as the diagnostic disk drive. Diagnostic programs are loaded into the diagnostic disk drive, which are selectively run by a user, such as by using the command shell. The method may also be configured to include data compression and decompression routines to increase the quantity of data that may be stored in the configured disk drive space, or encryption routines for security purposes. The diagnostic disk drive space may be used to store power on self test (POST) error logs in files that may be read by the operating system during its boot process and displayed by an event viewer.

A portable computer system has a light emitting diode (LED) indicator including multiple LEDs to display a power-on self-test (POST) state and an operating state of the computer system. When the portable computer system performs a POST process during system boot, the LEDs of the LED indicator are lighted in response to each step of the POST process. If any error is detected in the POST process, the POST process is stopped with lighting LEDs. The lighting state of the LED indicator indicates where the error has occurred in the computer system, so that a user can verify which element of the computer system has an error, without additionally adding a POST card to the computer system.

A drug infusion device determines whether an infusion program is stored within a memory. If so, a user is prompted to confirm usage of the program and a drug identifier, and to review the configuration of the device. If the program is not in the memory, the drug infusion device is enabled to receive an auto program with which it can configure itself. When auto program receipt is enabled, the drug infusion device waits for the auto program or for a selection for manual entry of the infusion program. A menu screen is displayed to indicate that the drug infusion device is waiting for the auto program, but the menu screen is not displayed if the auto program is already received. Therefore, a waiting for auto program menu screen may be avoided in many cases, reducing device setup time. In some embodiments, removal of a drug vial resets the device to a point after a power-on self-test and thus provides an easy method for resetting the device to a point that avoids unnecessary steps and expands a window of opportunity for receiving an auto program compared to prior work flows.

A computer system has a selectable set-up feature to adjust the display screen image presented during power on self test, or POST. The computer memory contains two sets of information that can be presented on the video display screen. An application of power to the computer system, a first form of information from a first video memory area is normally presented to the computer output device. This information is simpler in format, requiring less memory. Also, upon the application of power to the computer system, flags or semaphores direct substantially all of a detailed or verbose screen information from initialization, configuration, or other boot-time routines to a second video memory area while information in the first video memory area is presented on the display. Upon receiving one of a predetermined set of commands, the computer system switches from the first display to the second display, presenting the second verbose screen information on the video screen. The command may be internally generated upon execution of a group of instructions, or it may be received from an input device coupled to the computer system.

A method and system for controlling the addition of a USB device to a host computer system via a hardware hot plug detector that monitors USB ports. The differential signal lines connecting to the USB device are logically OR'ed together, such that logically high D+ or D− signals from the USB device signal a central processing unit's (CPU) system management interrupt (SMI) line to initiate system management mode (SMM). Entering SMM transfers control of the host computer system to an SMI Interrupt Handler BIOS, which resides in the SMM address space of the hose computer system. The SMM BIOS is loaded into the SMM address space during Power On Self Test (POST) and is secured prior to booting the Operating System (OS). The SMM BIOS code contains instructions as to whether or not the connected USB device should be made visible to the operating system of the computer. If the device is not authorized, it is disabled, the D+/D− lines are not connected to the USB host controller, and the SMI signal is cleared, allowing the computer to continue operation without the operating system ever being aware of the USB device.

A method and system for functional kernel verification testing within a data processing system is described. The method and system of the present invention performs imbedded functional verification test suites on selected kernel components within the data processing system when system administrator kernel component power-on self tests are required during an operating system boot operation. When an error is detected during the imbedded functional verification testing for a selected kernel component, it is reported based on the severity level. For a low or minor functional error, a warning is sent to the user and for a high or major functional error, the data processing system is immediately halted and a service call is generated. Additionally, to correct for the functional error, the data processing system may be enabled to de-install the most recent update of the kernel component.
