cpuid

Code:

.section .data
output:
	.ascii "The procesor Type is 'xxxxxxxxxxxx' \n"
.section .text
.globl _start
_start:
	nop
	movl $1, %eax
	cpuid
	movl $output, %edi
	movl %ebx, 27(%edi)
	movl %edx, 31(%edi)
	movl %ecx, 35(%edi)
	movl $4, %eax
	movl $1, %ebx
	movl $output, %ecx
	movl $42, %edx
	int $0x80
	movl $1, %eax
        movl $0, %ebx
        int $0x80

I took this program form a book, and it must print me 'Procesor Type, family, model, and stepping information'.
but when I run it :
$./cpuid
$The procesor Type ÿûƒxxxx'
where is the problem?
thx

I don't know what kind of program that is but you've asked it to actually print 'xxxxxxxxxxxx'... perhaps the 'xxxxxxxxxxxx' was supposed to be something else.

btw, this command will likely give you what you're looking for:
cat /proc/cpuinfo

but if your just practising programming, keep at it and good luck.
cheers

In the place of the x's must be the stuff I want.
Yout try the program yourself just put 0 in eax.
I tooked the program from the book Professional assembly language.
Where can I find about the AMD Processor?
