Right. (In Windows, you might want to do [fs:somevalue] - Windows uses fs for "thread local storage"(???) - a descriptor that does *not* have a base of 0, and limit is... 64k-1(???)... I think)
So if answer is yes, and if more than 4GBof memory space is needed for a program how will segmentation register go beyond 4gig without override?
Dunno. I'll leave that one to Hendrik. :) Best, Frank - To unsubscribe from this list: send the line "unsubscribe linux-assembly" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
