Scrolling Window and Expanded Memory with Intel X86 (AREV Specific)

I am runing AREV3.1 on a Windows 2000 Dell desktop (Dimension 4400.
Thanks

Dell and Compaq and HP often put their USB driver buffers and network card buffer addresses inside the memory region from 640 kB to 1mB - this is where AREV likes to set up its page frame address.
What you really need to do is examine the Windows Hardware device drivers (right click on My computer - Properties - Hardware - Device Manager and find out what is using segment register addresses immediately above A000h

You can run in EGA 80*50 or 80*43 character mode by setting the shortcut that way and also setting AREV's max screen length to 50 rows.

Screen size - Thank you Thank you - works great! I can now see 50 lines. There is no scroll on the entry screen as there is on the design screen. Any way to get the entry screen to scroll?
Mem - I looked through (not all!) the resources on the hardward device managers and did not find what was just above A000h. Two things are:
USB drivers uses EF40 - EF5F interrupt 19
Network card uses D400 - D4FF and FEAFEC00 - FEAFECFF interrupt 13
I also saw that the numeric data processors had no drivers installed with recources: 00F0 - 00FF and interrupt 13.
Where can I get a numeric data processor driver?
DOS mem /d shows:

Thanks for your help.

Try disabling the network card (temporarily) then calling AREV with and the /XM1024 switch - maybe you can trick it into working.
I recall a recent post by Barry Stevens re Compaqs which led in this direction.

There are some machines, no matter what you do, that just will not load up into EMS memory.
The only simply thing really left for you to try in this instance is to use the EMM command in the CONFIG.NT file.
<code> EMM=B=4000 RAM <code>
Take careful note of the spaces in the command line.
There are a few other options you can do. If your BIOS lets you, you can tell the BIOS not to use a plug and play OS. You can then go in and reconfigure the settings for your cards and move them to different areas of memory. What you'll need is 64K of memory in a single block between 640 and 1024 for EMS to allocate a full page frame.
If your BIOS does not allow this, then there are two other options available.
One is to reinstall your OS and tell it not to be a plug and play OS. That might let you reconfigure the memory settings, but there is no guarantee.
The other is to get a virtual machine running, which can run DOS. This is the solution I ended up with on my laptop. I used VMWare, created an MS DOS 6.22 VM, loaded Windows 3.11, and run AREV through there. I needed Windows 3.11 because I couldn't find network drivers that would run in pure DOS mode.
The network drivers are to allow you to map from the VM to the rest of the machine. So, I have my Revelation subdir mapped as X. All my systems then map to X and I access the software from there.
You might have better luck with FreeDOS or DOS32 or one of the other DOS alternatives out there, but for me doing the old DOS/Win3.1 was quick, fast and easy, and gives me full EMS memory (at the cost of some disk space for the VM). All in all, a fair trade, really.
