| * Partition Header |
| * 00h - signature ( 1 byte) |
| * 01h - checksum ( 1 byte) |
| * 02h - length ( 2 byte) value = 1st_byte*256 + 2nd_byte |
| * 04h - name (12 byte) |
| * space for partiton header = 16 byte |
| * |
| * Log Header |
| * 10h - offset ( 2 byte) from Partition Header to Data Section |
| * 12h - flags ( 2 byte) control flags |
| * 14h - pointer ( 4 byte) pointer to first free byte in Data Section |
| * relative to the beginning of the data section |
| * 18h - zero ( 32 byte) reserved as stack for four 64 bit register |
| * 38h - reserved ( 8 byte) reserved for 64 bit CRC (not implemented yet) |
| * space for header = 64 byte |
| * Data Section |
| * 40h - cyclic data |
