I need to use this part of memory. Please help me—what software should I use, where can I get it, and how should I set it up? Please enlighten me, experts!

Just add the relevant parameters and address when loading emm386.exe. But I can't find any related documentation at the moment.

B000 to B7FF is all monochrome memory area

The EMM386.EXE line in my CONFIG.SYS is like this: DEVICE=EMM386.EXE NOEMS NOVCPI I=B200-B7FF Because using the area between B000-B200 may cause system instability, I didn't use it, only B200-B7FF.

It is said that using EMM386.EXE will make the system enter protected mode, and ordinary programs run in virtual x86 mode, affecting performance, so I want to use UMB in real mode.

That's right, use UMBPCI, a very powerful and practical real-mode UMB program. It's included in all of the MS-DOS 7.10 boot disks we made. For specific usage, please see the related introduction on the website.

I used UMBPCI, but the UMB I got is less than 70K, so I want to supplement it with the monochrome memory area, but I don't want the system to enter protected mode. What should I do?

device=C:\Umbpci.sys /i=cc00-efff This should work, right?

On my machine this setting will crash the system; only using its detected values (D400-DFFF,EC00-EFFF) works normally. I wonder if there is any software that can manage the monochrome memory area in real mode? Also, HIRAM.EXE crashes on my machine (running it at the prompt is fine, but using it in Config.sys makes it crash). I don't know what parameters it has, so I can try setting it. In addition, on my machine Cloaking.exe version 2.01 absolutely refuses to stay resident in UMB, while the 1.x version in the moderator's boot disk cannot stay resident. My machine specs: Celeron4 1.7G,Acorp 4D845G motherboard, no floppy drive, using a flash drive as USB-HDD boot, MS-DOS7.10

Maybe software like HIRAM doesn't have very good compatibility with some computers. Unfortunately I don't have that hardware to test. Because on my computer, everything runs normally.
