For some reason here I’m very confused why its jumping to putsc16 after returning from puts32_done? I Tried investigating this heavily but so far no bite, would appreciate some guidance. All code is here: https://github.com/amanuel2/boot_temp

These are the relevant parts:

Code:

    movl %cr0, %eax
    orl $1, %eax
    movl %eax, %cr0 # (we are now in protected mode)

    # Far jump to stage2
    ljmpl $CODE_SEG32, $pmode_entry

.code32
.align 4
pmode_entry:
    cli # Make sure to disable interupts before protected mode or triple fault
    movw $DATA_SEG32, %ax
    movw %ax, %ds
    movw %ax, %es
    movw %ax, %fs
    movw %ax, %gs
    movw %ax, %ss

    # Set up a stack (make sure this area is writable)

    # Debug: Write directly to video memory
    movl $0x0f, %eax  # 'PP' in white on black
    movl $0xb8000, %edi
    movl %eax, (%edi)

Code:

puts32:
    pushl %ebp
    movl %esp, %ebp
    pushl %ebx
    movl 8(%ebp), %ebx  # Get string address from stack
    movl $0xb8000, %edx # Video memory address
    movb $0x0f, %ah     # White on black attribute
puts32_loop:
    movb (%ebx), %al
    testb %al, %al
    jz puts32_done
    movw %ax, (%edx)
    addl $1, %ebx
    addl $2, %edx
    jmp puts32_loop
puts32_done:
    popl %ebx
    leave
    ret
