Desktop Management Guide HPQFlash The HPQFlash utility is used to locally update or restore the system ROM on individual PCs through a Windows operating system. For more information on HPQFlash, visit http://www.hp.com/support/files and enter the name of the computer when prompted. FailSafe Boot Block ROM The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, for example, if a power failure were to occur during a ROM upgrade. The Boot Block is a flash-protected section of the ROM that checks for a valid system ROM flash when power to the system is turned on. ■ If the system ROM is valid, the system starts normally. ■ If the system ROM fails the validation check, the FailSafe Boot Block ROM provides enough support to start the system from a ROMPaq diskette, which will program the system ROM with a valid image. ✎ Some models also support recovery from a ROMPaq CD. ISO ROMPaq images are included with some models in the downloadable ROM softpaqs. When the boot block detects an invalid system ROM, the System Power LED blinks RED 8 times, one every second, followed by a 2-second pause. Also 8 simultaneous beeps will be heard. A Boot Block recovery mode message is displayed on the screen (some models). To recover the system after it enters Boot Block recovery mode, complete the following steps: 1. If there is a diskette in the diskette drive or a CD in the CD drive, remove the diskette and CD and turn off the power. 2. Insert a ROMPaq diskette into the diskette drive or, if permitted on this computer, a ROMPaq CD into the CD drive. 12 www.hp.com Desktop Management Guide
