네임서버(DNS)셋팅 급질문

네임서버 셋팅 처음 해봅니다... 급하게 꼭 해야 하는데.... 에러가.. ㅠㅠ

현재 서버1대이고 DNS서버겸 웹서버로 사용하려 합니다.
Redhat 9.0 이구요..bind-9.2.4-2.i386.rpm을 깔았습니다.
아직 아파치는 깔지 않았구요.. 도메인 호스트와 네임서버는 제 아이피로 잡혀 있는 상태입니다.
그런데 오류가 생기는군요...
오류메시지와 관련파일들입니다. 좀 봐주세요...
보안상 제 도메인은 korea.com으로 아이피는 000.000.000.000 으로 적었습니다.
그리고 있으면 안될 구문.. 없어도 될 구문.. 등등... 구체적인 도움 부탁드리겠습니다...
