Abstract: According to examples, an apparatus may include a power circuit to transmit standby power to a device, a memory associated with the device to maintain first configuration data and second configuration data and a battery to provide backup power to the device. The device may, following a loss and a recovery of the standby power to the device, determine whether the backup power was lost during the loss of the standby power. The device may also, based on a determination that the backup power was lost during the loss of the standby power, read the first configuration data or may, based on a determination that the backup power was not lost during the loss of the standby power, read the second configuration data. The device may further apply the read one of the first configuration data or the second configuration data to configure the device.

Abstract: In some examples, in response to a computing device powering on, a protected memory area inaccessible to an operating system is created, where the protected memory area includes information relating to instructions and an indication settable to a first value to indicate that the instructions are allowed to access a memory external of the protected memory area, and a second value to indicate that the instructions are not allowed to access the memory external of the protected memory area. In response to creating the protected memory area, the indication is modified from the first value to the second value to restrict the instructions when executed from accessing the memory external of the protected memory area. In response to modifying the indication, code in the computing device is launched, the launched code comprising the operating system or firmware.

Abstract: Examples disclose a method, system, and computer readable media to configure a device within a computing system. The examples process configuration data when standby power is applied to the device. Additionally, the examples configure the device based on the configuration data, wherein the device is configured prior to initialization of the computing system.
