Abstract
A method, computer system, and apparatus perform a modified simple boot. Rather than following Ver. 1 of the Simple Boot Flag Specification, the simple boot flag is ignored if certain platform corruption errors are detected by the BIOS. When the simple boot flag is set, the BIOS runs through a set of core diagnostics to determine whether a platform corruption has occurred. If BIOS detects that the simple boot flag is set and that no platform corruptions have occurred, then a simple boot is performed. However, if a platform corruption is detected, the set simple boot flag is ignored and a full suite of diagnostics routines is performed by the BIOS during the boot process.
