linux分区的前512字节内容是什么?。。。。。。。。。
想问的问题在这里:http://www.linuxsir.com/bbs/showthread.php?s=&threadid=38611 i can not resolve the dns. but u can use dd and hexedit to see 这个得看分区的性质吧?如果启动分区,应该是引导程序的代码,如果非引导区就不知道应该是什么了 similar, this 512 is reserved for these use. 那512B是一段启动代码,它是代码树下面的arch/i386/boot/bootsect.S,可以看一下。
主要是先将它其它启动用的代码都装入合适的位置,然后执行,从而启动整个系统。 yes, for boot partition it is. we mean all partitions. so some are not.:wink::wink: i am so sorry i haven't online for years because of working and examing of graduate, so i haven't time to learn linux and didn't see the brother's answer for me,sorry. now i go back school , i'm in Wuhan Research Institute of post & electronic , and i still busy, and i still love linux, i hope i can discuss with all brothers online sometimes.
i am so sorry i haven't online for years
