Simple CPUID, I also experimented with a version using an extra buffer variable and printf. It may not be much to others but I'm learning!

; CPUID

section .data
	buffer: 		db 	"CPU Vendor ID: XXXXXXXXXXXX", 10, 0
	bufferlen: 		equ 	$ - buffer

section .text
	global _start

_start:
	mov 	eax, 0 			; "Get maximum supported standard level and vendor ID string"
	CPUID 				; Call CPUID
	mov 	[buffer+15], ebx 		; Move 4 bytes from ebx to buffer+15
	mov 	[buffer+19], edx 		; Move 4 bytes from edx to buffer+19
	mov 	[buffer+23], ecx 		; Move 4 bytes from ecx to buffer+23

	mov 	eax, 4 			; write syscall
	mov 	ebx, 1 			; stdout
	mov 	ecx, buffer 			; buffer
	mov 	edx, bufferlen 		; size of buffer
	int 	80h 				; call kernel

_exit:
	mov 	eax, 1 			; exit syscall
	mov 	ebx, 0 			; Return 0
	int 	80h 				; call kernel
