hi, i've wrote a bootloader code for fat32 file system, and there is something strange in binary format after compiling.

this is code:
;<<<<<<<<<<start>>>>>>>>>>>>
jmp start_code
nop

oemname db 'MSWIN4.1'
bytespersector dw 512
sectorspercluster db 8
ressectors dw 38
numcopiesfat db 2
maxallocrootdir dw 0
maxsectors dw 0
mediadescriptor db 0f8h
sectorsperfat dw 0
sectorspertrack dw 63
heads dw 64
hiddensectors dd 63
bigsectors dd 3173121
bigsectperfat dd 3093
fatflags dw 0
version dw 0
firstclustofroot dd 2
fsinfosector dw 1
backupbootsect dw 6
reserved dd 0,0,0
driveid db 80h
rezervat_nt db 0
bootsignature db 029h
volumeid dd 56291043h
volumelabel db 'ChristmasOS'
filesystemtype db 'FAT32 '

start_code:
; here is the rest of code

I know that the first 3 bytes in a fat32 boot loader should be EB 5A 90
but i had seen on some partitions that byte 5A is 58. Wich is the correct one? I also want some code for reading and/or loading a file from a fat32 partition.

use [code] tags around your code

Just use

You will find bootloader code for fat12, fat16, fat32 written ASM, C, brainf**k .
Also available in red, green, and blue.
Also nice load file from fat32 in asm you can copy, i mean look at.
