Can Qemm386.sys replace himem.sys? I only use QEMM386 to support UMB, EMS, and XMS at the same time

QEMM386 can be replaced by QEMM386, and it has more powerful functions than them. For example, it can create up to 704K of conventional memory. Of course, there will be more compatibility issues.

It can be used for specific system boot disks, but it is best not to use it for general-purpose boot disks.

In a general startup disk, just use EMM386 and UMBPCI, etc. My MS-DOS 7.10 startup disk is like this:

Yes
QEMM386 easily causes memory conflicts
Now when I use HD-copy, it always fails to run

You can use Qemm386! Could you post your config for me to take a look?

I can also use!!

Can you also post the memory allocation?

OK!!
