2 Structures
All integer fields in the OAB structures are unsigned and use little-endian byte order.
The server calculates all CRC hash values by using the IEEE 802.3 CRC polynomial of 0xEDB88320 (x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1) which is seeded with the value 0xFFFFFFFF. For more details, see [ISO/IEC8802-3] section 3.2.8.
The server packs all structures on single byte boundaries.
The server measures all offsets in bytes from the beginning of the specified file.<1>
