I loaded this code off of the disk at 0x1000:0x0000
Here is the memory address of wtf being pushed onto the stack in segment 0x1000, then returning to segment 0:
mov ax, wtf
push ax
push ds
mov ax, 0
push ax
mov ax, word [ds:0x1000]
push ax
retf ;going back to segment 0
wtf db 'hi', 0
and here is me trying to access the memory address from segment 0
mov ax, 0x1000
mov ds, ax
mov ah, 0x0e
mov al, byte [ds:0x004e]
int 0x10
im using 0x004e because that is the value that got pushed onto the stack with push wtf.
However, int 0x10 outputs null and still moves the cursor. The expected output would be 'h'...
What is going on here?
