Day, it sounds like you want both OS "active" at the same time, or? What sort
of hardware are you running on? I recall from way-back-when that you'd tried
DOSemu but didn't like it? It might be worth another shot, because you could
certainly have a very basic Linux system running in the back to get you online,
then "connect" to it from DOS using DOSemu. I've done this to run some
venerable old wardialing DOS software.

You probably want a Linux system configured with a "framebuffer" enabled
display. These will run fine even on basic VESA-compatible video cards.
Depending on what distribution you're using, the kernel may already be
configured this way.

If you put "vga=ask" in lilo.conf (assuming you're using lilo as your boot
manager), the system will stop and ask you which display mode to use. With a
bit of poking, you may well find one that fits your needs, in which case Linux
will simply run in that mode. There are tools to conver on-the-fly, but I've
not tried them, so can't offer any meaningful advice.

Now, I don't know that this will necessarily do anything for DOS sessions
running under DOSemu. Here's a snippet from the Debian description of the
latest package:

Description: The Linux DOS Emulator
 DOSEMU is a PC Emulator application that allows Linux to run a DOS
 operating system in a virtual x86 machine. This allows you to run
 many DOS applications.
  - Color text and full keyboard emulation (via hotkeys) via terminal.
  - Built-in X support, includes IBM character set font.
  - Graphics capability at the console with most compatible video cards.
  - DPMI support so you can run DOOM.
  - CDROM support.
  - Builtin IPX and pktdrvr support.

The framebuffer solutions will let you use alternate fonts, but again, I've not
done it, nor is it particularly straightforward.

I find the same when reviewing bootup screens for errors, reviewing logs etc.

A minimal GUI with a resizable xterm should let you resize your display on the
fly. Even at 800x600 resolution (not a particularly hard target to reach), I
can resize using 10pt. courier font to get 95x35 resolution.At 1280x1024, I can
get 155x66 and still have very readable text (depending on how tired I am). A
lightweight GUI (i.e. icewm, fvwm) should come up quickly. You could have it
configured to do nothing BUT launch an xterm window, then from there launch
DOSemu.

Just some thoughts.
