一个DOS7.10启动盘，加载了himem和emm386.exe内在使用情况如下：


Memory Type Total = Used + Free
---------------- -------- -------- --------
Conventional 640K 261K 379K
Upper 81K 16K 66K
Reserved 303K 303K 0K
Extended (XMS) 64,512K 2,476K 62,036K
---------------- -------- -------- --------
Total memory 65,536K 3,056K 62,480K

Total under 1Mb 721K 277K 444K

Total Extended (XMS) 64,512K (66,060,288 bytes)
Free Extended (XMS) 62,036K (63,524,864 bytes)

Largest executable program size 342K (350,320 bytes)
Largest free upper memory block 64K (65,616 bytes)
Available space in High Memory Area 0K (32 bytes)
MS-DOS is resident in the high memory area.

但当运行一个软件时，它老是提示：Not enough RAM.

请问要怎样处理才能运行此软件？

"conventional 640K 261K 379K"

怎么常规内存只剩300多KB了？

是啊，先运行A程序后常规内存只剩300多KB了，再运行B程序时就提示Not enough RAM.
如果一定要先运行A程序，又使B程序能正常运行，有何办法？

A程序叫NTFSDOS，有关它的说明如下：
* NTFSDOS uses too much conventional memory

Some people have complained that NTFSDOS is a memory hog. Unfortunately,
this fact is largely imposed on us by the architecture of NTFS itself
(sorry, but its a *little* more complicated than FAT, and much more memory
intensive), coupled with our desire to provide reasonable performance
across a wide variety of NTFS installations. In general, the footprint
of NTFSDOS increases largely with the clustersize of the largest NTFS
partition, and slightly with the number of NTFS volumes mounted. If the
NTFS drives you will be accessing do not contain compressed files, you
should use the /N option to lower NTFSDOS' memory footprint.

如果一定要运行NTFSDOS，又使常规内存保留600多K，要怎样设置？

休想！
