1) 커널이미지 압축을 푸는 과정입니다.
2) 커널 버전 및 커널을 컴파일한 시간, 컴파일러 버젼 등을 나타냅니다.
3) 타켓 머신의 이름을 알려 줍니다.
4) 커널 커맨더 옵션을 표시해 줍니다. 부트로드에서 넘겨 줄 수도 있으며, 커널 소스에서도 가능합니다.
5) 콘솔로 사용된 UART를 알려 줍니다.
6) 프레임버퍼 관련 내용입니다.
7) UART관련 정보입니다. 현재 EZ-S3C6410은 4개의 UART가 잡혀 있습니다..
8) 이더넷 관련 정보입니다. 맥주소는 커널 커맨드로 넘어오는 mac=00:FA:06:A6:03:33 로 설정한다.
9) NAND 파티션 관련 정보입니다.
이 정보는 커널 커맨드로 넘어오는 nandparts=4,13,495 에 의해 파티션을 잡습니다.
10) USB host 및 otg 관련 정보입니다.
11) S3C6410 내부 RTC 및 I2S관련 정보입니다.
12) 사운드 관련 정보입니다.
13) yaffs 파일시스템 관련 정보입니다.
14) 이 이후는 램디스크 관련 내용입니다.
