Abstract
An information handling system includes a plurality of persistent memory devices and a basic input/output system (BIOS). The BIOS begins a power-on self-test (POST) of the information handling system. During the POST, the BIOS may call a block input/output (I/O) driver to access a memory region within the first persistent memory device. The access of the memory region within the first persistent memory device is to determine whether the first persistent memory device is a bootable persistent memory device. The BIOS may determine whether blocks of the memory region contain bad memory locations. In response to the memory region containing bad memory locations, the BIOS may return a device error message without performing the access of the blocks of the memory region within the first persistent memory device and may boot to an operating system of the information handling system via another bootable device.
