UCDOS 7.0 display issue in VMware Workstation 15.5.0 and 16.2.0 Player

Hi,

I downloaded VMware Workstation 16.2.0 Player (the newest by now, as of Oct. 2021), and tried running UCDOS 7.0 on MS-DOS 6.22 in it. However, UCDOS still has the same display issue as I saw in VMware Workstation 15.5.0 Player.

The attached image shows the screen after it is started.

The screen is a VGA 640x480 screen. The first five lines of text (about 88 pixels in height, as I measured) cannot be seen.

UCDOS 7.0 runs perfectly on Bochs (2.6.9). I remember that it ran also fine on some earlier version of VMware.

Would you please check if the display compatibility issue can be resolved?

Thanks,
Decheng

Never heard of UCDOS, but I have several plain MS DOS 6.22 virtual machines which all run perfectly fine under Workstation 16.2.0 (and have for many prior versions as well).
