Abstract
A Basic Input/Output System (BIOS) of a device is modified to: obtain a first value from a medium interfaced to the device, produce a second value from boot data resident on the medium, compare the first value to the second value, and boot from the boot data of the medium when the first value is equal to the second value.
Claims20
A method, comprising:
- obtaining header information from a portable non-transitory computer-readable storage medium;
- removing a value from the header information;
- and
- comparing the value against a generated value produced by processing data on the portable non-transitory computer-readable storage medium.
1 more element
A method, comprising:
- configuring a hash process to generate a hash value from boot data residing on a portable non-transitory computer readable storage medium;
- modifying a Basic Input/Output System (BIOS) to obtain a second hash value from header information residing on the portable non-transitory computer readable storage medium;
- modifying the BIOS to process the hash process;
- modifying the BIOS to compare the hash value against the second hash value;
- modifying the BOIS to boot a device associated with the BIOS from the boot data when the hash value equals the second hash value;
- and
- certifying the modified BIOS for installation on the device.
4 more elements
A Self-Service Terminal (SST), comprising:
- a device port;
- a Basic Input/Output System (BIOS) adapted and configured to:
- i) obtain a first hash value from a non-transitory computer readable storage medium interfaced to the device port, ii) generate a second hash value from boot data resident on the non-transitory computer readable storage medium, and iii) boot the SST from the boot data when the first hash value equals the second hash value.
