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
