about of ibm ps/55 https://ja.wikipedia.org/wiki/PS/55

there are few that have them and it was emulated in 86box

without the japanese video adapter the operating system will not run.

when I run in ps/55 mode graphics did not load after load

switching to ps/2 mode using switch included in ibm japanese dos will run

Can you share your 86Box configuration? I haven't found the PS/55 machine in the list (using 86Box 4.2.1)
