On IBM PC-compatible computers, the bootstrapping firmware (contained within the ROM BIOS) loads and executes the master boot record. [23] The PC/XT (type 5160) used an Intel 8088 microprocessor. In order to remain compatible, all x86 BIOS architecture systems start with the microprocessor in an operating mode referred to as real mode.
Operating systems that use SLP 1.0 check for a particular text-string in a computer's BIOS upon booting. If the text string does not match the information stored in the particular installation's OEM BIOS files, the system prompts the user to activate their copy as normal.

There is a Master Password identifier feature which, if supported and used, can identify the current Master Password (without disclosing it). The master password, if set, can used by the administrator to reset user password, if the end user forgot the user password.

Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid full disk encryption) or with a BIOS password. In additions, some SEDs are support IEEE 1667 standard. [2]
