Abstract
A method and information handling system (IHS) that optimizes boot time. The method includes a basic input output system (BIOS) performing an authentication check of drivers during an initial boot process. The results of the authentication check are stored along with an unified extensible firmware interface (UEFI) image for each driver in an authentication results data structure (ARDS). In response to receipt of a subsequent request to enable a secure boot of the IHS, when the initial boot process was performed with the secure boot disabled, the ARDS is accessed to determine if any of the drivers failed the authentication check. When none of the drivers have failed the authentication check, the boot process is continued using the UEFI images of the drivers. When at least one of the drivers has failed its authentication check, a notification is output indicating a failure of the authentication check.
