현재 kernel2.4.10를 사용하고 있습니다. 2.4.18로 up한다음 MTD, jiffs를 사
용하려고 합니다. 강의에 가보면 kernel부분에 설명서를 읽었습니다. 그리고
자료실에서 ezboard에 맞게 patch가 되어 있는 2.4.18를 downloading하였구
요. 이전의 ramdisk를 사용하는 상태에서 2.4.18의 zImage를 올리면 다음과 같
은 message가 나옵니다.

"플래시 롬을 root로 만드는 과정"
"플래시 롬을 root로 만드는 과정(램디스크 image영역없이)"
플래시 롬을 root로 만든다는 것이 무슨 말인지, 램디스크 image영역없이 라
는 말은 무슨 말인가요? 그리고 "zlib 라이브러니 포팅"은 무슨 말인가요?
이전의 ramdisk로는 사용을 할수 없는건지요..
