What you want

Console redirection which together with allow more than 640kb base memory will free Conventional memory to reach up to 960KB and above.

It was also possible to use console redirection (either by specifying an alternative console device like AUX: when initially invoking COMMAND.COM or by using CTTY later on) to direct output to and receive input from a dumb terminal or another computer running a terminal emulator. Assuming the System BIOS still permitted the machine to boot (which is often the case at least with BIOSes for embedded PCs), the video card in a so called headless computer could then be removed completely, and the system could provide a total of 960 KB of continuous DOS memory for programs to load.

Redirect to AUX/COM with nullmodem to localhost Telnet or similar.

To determine how high the memory will reach - how big is DOSbox-X BIOS?

• IBM PC/5150 BIOS was occupying only the top 8KB
• What is the lowest address in the BIOS range that software may use/call? I assume DOSbox BIOS area can be limited to that point.

Additional information

Possible further improvements:

• disabling boot ROM after boot-up (or emulating SCP-200B/86-DOS), so that the whole 1MB can be reached - allowing to perform "linking the linker" like Microsoft did before 386 was available.
• Render to console #5415 (comment) (host console, etc.)
• input remains redirected to COM, but output to LPT for a kind of rudimentary graphics (Sixel like CP/M, color/graphics modes on VT241/VT340/VT420)
