fat32 - File systems and the boot parameter block: -


i read tutorial writing bootloader. author gave example of boot parameter block:

bootsector:  ioem:          .ascii "devos   "    # oem string  isectsize:     .word  0x200         # bytes per sector  iclustsize:    .byte  1             # sectors per cluster  iressect:      .word  1             # #of reserved sectors  ifatcnt:       .byte  2             # #of fat copies  irootsize:     .word  224           # size of root directory  itotalsect:    .word  2880          # total # of sectors if on 32 mb  imedia:        .byte  0xf0          # media descriptor  ifatsize:      .word  9             # size of each fat  itracksect:    .word  9             # sectors per track  iheadcnt:      .word  2             # number of read-write heads  ihiddensect:   .int   0             # number of hidden sectors  isect32:       .int   0             # # sectors on 32 mb  ibootdrive:    .byte  0             # holds drive boot sector came  ireserved:     .byte  0             # reserved, empty  ibootsign:     .byte  0x29          # extended boot sector signature  ivolid:        .ascii "seri"        # disk serial  acvolumelabel: .ascii "myvolume   " # volume label  acfstype:      .ascii "fat16   "    # file system type

if using fat32 file system can change last part (acfstype: ascii “fat16 “) , use boot parameter block? if not can boot parameter block fat32?

i asked mike saunders ( author of mike-os) in email , answer no. can't use table fat32 changing (acfstype: ascii “fat16 “)part. boot parameter block fat32 file-system sent me this link microsoft website.
