안녕하세요..
오늘도 어김없는 질문공세입니다.(^^)
ez-x5 보드를 부팅하고 나서 하이퍼터미널에서
dmesg 명령어를 쳐서 내용을 보던중에서요..
아래와 같은 메시지가 나타났습니다.
Memory clock: 99.53MHz (*27)
Run Mode clock: 398.13MHz (*4)
Turbo Mode clock: 398.13MHz (*1.0, inactive)

이부분중에서 security risk 다음에.. 어쩌구 저쩌구라고 나타나는데..
이부분이 어떤의미인지.. 제가 뭘 잘못한것인지 알고싶습니다.
ez-x5.c 파일에는 다음과 같이 되어있었습니다.
/*
* IO map for the devices.
*/
static struct map_desc ez_x5_io_desc[] __initdata = {
/* virtual physical length domain r w c
b */
