The fragment shoul be:
0x000-0x002 Jump instruction
0x003-0x00A 8 bytes OEM String ("MSDOS 5.0", for example)
0x00B-0x00C Bios Parameters Block - BytesPerSector
Usually 00 20 = 512 and not 07 50 = 20.487
0x00D-... Other BPB, Boot code etc etc.
0x01BE... Partition table
0x1FE Signature (55 AA)
DOSF requires a correct (512/1024/2048) value at 0x00B/C, so breaks before
trying to access the other data ...
