안녕하세요
 얼마전에 안 사실인데.. 저희집 리눅스가 DMA를 못잡는것 같습니다 T.T
 우연히 안건데.. DMA가 잡혀 있으면 (U)DMA라고 하드디스크 옆에 표시가 되어야 한다네요
 흐미... 도통 방법을 모르겠습니다... 당연히 바이오스에는 UDMA가 잡혀있고 윈도우즈에서
도  DMA를 활성화 하여 사용중입니다..
 하드디스크는 웬디 30GB 5400RPM입니다. 보드 칩셋은 TX구요.
 리눅스 운영체제는 와우 리눅스 6.2 UPDATE 입니다.
 일단 저의 dmesg 로그파일을 올려드릴께요

 혹시 비슷한 경험을 가지고 계시거나... 아시는분 답변 부탁드립니다
 (근데... 여러 사이트에서 검색을 해보니 컴파일을 다시 해줘야 한다는군요. 무슨 방법이 
없을까요...)
