Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I read in the FreeBSD handbook on PC memory usage: Since it has been linked for another (high) address, it will have to execute PIC until the page table and page directory stuff is setup properly, at which point paging will be enabled and the kernel will finally run at the address for which it was linked. Can anyone explain to me what is PIC and the two different linked addresses mentioned here? Thanks for your help. -------------------------------------------------- | Zhihui Zhang, http://cs.binghamton.edu/~zzhang | | Dept. of Computer Science, SUNY at Binghamton | -------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
