Configuration of config.sys file to get 700K available memory for DOS - China DOS Union Forum

On the website of the China DOS Union:

"http://zhenlove.com.cn/cndos/newdos/dosuse.htm" configure the c:\config.sys file, use the following configuration, and the available memory of DOS is close to 700K!

device=c:\windows\himem.sys/testmem:off
device=c:\windows\emm386.exe noems novcpi
device=c:\windows\ifshlp.sys

dos=high,umb,auto
stacks=12,256
files=30

numlock=off

Modules using memory below 1 MB:

Free 666,032 (650K) 617,648 (603K) 48,384 (47K)

Memory Type Total Used Free
---------------- -------- -------- --------
Conventional 640K 37K 603K
Upper 80K 33K 47K
Reserved 304K 304K 0K
Extended (XMS) 68,608K 5,185K 63,423K
---------------- -------- -------- --------
Total memory 69,632K 5,559K 64,073K

Total under 1 MB 720K 70K 650K

Largest executable program size 603K (617,632 bytes)
Largest free upper memory block 47K ( 47,680 bytes)
Windows is resident in the high memory area.

640K conventional memory plus 80K upper memory can reach 720K.
Generally, it is no problem to keep conventional memory above 600K.

The size of the upper memory is related to the motherboard. For example, I have an 865 motherboard. No matter whether I use EMM386 or UMBPCI, and even add the /I parameter, the upper memory = 0.

Not worth mentioning, QEMM should be 635K + 150K

I like using umbpci + hiram, and can't think of anything better than this.

As for getting the maximum amount of conventional memory.

I think hiram seems not very useful, oh!?

Everyone, let's talk about how to maximize the upper memory and available conventional memory.

Asking for everyone's QEMM usage?
