How to disable the welcome message when running qemu+seabios?

[freedom1b2830]

I see
SeaBIOS (version Arch linux 1.16.3-1-1)
iPXE (link)

I need only the text of my program to remain in the window

I start the VM like this:
qemu-system-i386 ./boot

[ddatsh]

put some clear screen code before, like

mov ax,0x600
mov bx,0x0
mov cx,0x0 
mov dx,0x184f
int 0x10
mov dh,0x0
mov dl,0x0
mov bh,0x0
int 0x10
