作者: Wengier 时间: 2005-4-21 00:00 我發現你好像真的有點問題。我再重復一遍上面說的話:
“首先說明,對於MS-DOS 7.10來說,這在正常情況下是根本不可能發生的事情!MS-DOS 7.10的一大特點就是支持大內存,它的HIMEM.SYS支持最大4GB的內存,根本不可能被局限於64MB左右(MS-DOS 6.x及許多其它的舊版本DOS才會這樣),比如我自己機器中的256MB、512MB等內存在MS-DOS 7.10下就可以全部正常識別,其他版主和網友也從來沒遇到過你說的這種問題。衹有以下可能,那就是你用的HIMEM.SYS並非MS-DOS 7.1啟動盤中自帶的HIMEM.SYS,而是別的HIMEM.SYS被放在這兒用(這是很有可能的);或者你使用的查看內存的軟件有問題,即與你在WinME的DOS下使用的工具不同...”
另外,當然還有其它可能,比如說啟動盤中加載的程序不同,而有極少數程序可能導致內存大小的顯示失常。
MS-DOS 7.10是全面支持大內存是很明顯的事實,如果你覺得不對那就是你自己的做法有問題(包括上面列舉的各種可能性等)。我自己做過各種DOS啟動盤,MS-DOS 7.10啟動盤就做過好幾個並讓大家下載使用,難道我對這些基本的事實還不知道?不過我發現你用的啟動盤不知是哪兒下載的(應該不是在本站中下載的),可能是有問題,要不然你自己再到本站中去下載一個MS-DOs 7.10啟動盤來試試,比如這兒:

以下是在我的一臺256MB的電腦上用基本的MS-DOS 7.10啟動盤(啟動盤中沒有加載很多程序)運行MEM/C命令的結果,根本不存在你說的所謂“問題”:
