This is a personalized DOS system I configured myself, and I have been using it for many years. It feels very convenient. Among them, option 2 can recognize the USB flash drive, but one of the three boot options in the BIOS needs to be adjusted to ZIP boot.
I also selected 2 image viewing software in it, pictview and qv. I personally feel that the pictview image viewing software is more user-friendly.
Originally, there was also a player under DOS, but I felt it was useless, so I removed it.
I originally configured the DOS system using WinImage and Microsoft's virtual computer. After configuring the DOS system, I knew which software is the most useful today and which software should be eliminated in today's era.
I originally configured this all-DOS system purely for learning DOS. My initial enlightenment tutorial for learning DOS was the DOS articles from Hong En Computer. Fortunately, today when I go to read those articles, they are still so classic.
