Well, of course! %es:(%edi) does _not_ mean $es+$edi, it means that
$edi is used to address the section whose segment descriptor's index
(a.k.a. selector) is in $es. That is, in your case, 0x7b is the
selector that identifies the segment descriptor of the section where
blob1[] is stored (.bss, if my rusty memory doesn't deceive me).
Am I missing something? If not, what was this example supposed to
prove, exactly?
