I want to make a partition for the floppy. This makes it easier for me to manage files and code.
So the task of bootload (512 bytes) is to load a file "BOOT" up to start phase 2

Hello sir Bogdan.
I'm having trouble with my bootloader code.
The code size after the build exceeds 512 bytes.
You can optimize jump functions in 16bit mode

Code: [Select]

je label ; 4byte "0F 84 XX XX"
je short label ; 2byte "74 XX"


Code: [Select]

jmp label ; 3byte "E9 XX XX"
jmp short label  ; 2 byte "EB XX"

If you can provide or add the following functions in 16bit mode

Code: [Select]

ljmp segment:offset ; jmp segment:offset

mov {reg},[es:{reg}] ; mov ax,[es:di]
mov {reg},[ss:{reg}] ; mov ax,[ss:di]
