hi!

how are you today?
;-)

well, with your error code, I think that what i said yesterday was right:
your syntax at

mymsg: 
	.byte 13,10 
	.ascii "Handling BIOS interrupts"

[...]

	movw $mymsg,%bp 

But as I don't know about At&t syntax, here is an example of good syntax

$ cat write.s
.data
hw:
	.string "hello world\n"
.text
.globl main
main:
	movl	$SYS_write,%eax
	movl	$1,%ebx
	movl	$hw,%ecx
	movl	$12,%edx
	int	$0x80
	movl	$SYS_exit,%eax
	xorl	%ebx,%ebx
	int	$0x80
	ret


For At&t / intel syntax, please refer to:
www.linuxassembly.org
or more precisely:
http://www.linuxassembly.org/linasm.html


happy new year!

;-)
Fred
