Extended Boot Record - EBR Structure and Values

EBR Structure and Values

EBRs have essentially the same structure as the MBR; except only the first two entries of the partition table are supposed to be used, besides having the mandatory boot record signature (or magic number) of 0xAA55 at the end of the sector. This 2-byte signature appears in a disk editor as 0x55 first and 0xAA last, because IBM-compatible PCs store hexadecimal words in little-endian order (see table below).

Famous quotes containing the words structure and/or values:

    Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.
    Sydney J. Harris (1917–1986)

    The vulgar crowd values friends according to their usefulness.
    Ovid (Publius Ovidius Naso)
