Describe the bug
At bootup, the system beeps one long time and two short times which means display error. Then the system does its mem check and display a 2401 error that also means display error because the video controller wasn't set to Internal

To Reproduce
Steps to reproduce the behavior:

1. Go to Display section
2. Click on Video
3. Select other controller than internal
4. See error 2401

Expected behavior
86box should emulate the internal controller AND the external one but eventually display only the external video controller

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu 22.04 on Intel Core 2 Duo
• 86Box version: 86box v.4.0 build 4758
• Build information: x86_64 dev build

Additional context
That was the first time it emulated the IBM PS/2 so it didn't have an NVR and time sync was disabled -> 162/163 errors
and it is an AppImage build that has been extracted
