Hercules Monochrome Graphics in VMware Server

  • 1.  Hercules Monochrome Graphics in VMware Server

    I'm looking for a way to connect to a virtual Hercules Graphics card (monochrome monitor) that will support text and graphics modes in VMware Server. When the virtual machine starts it has the main window which changes between text and graphics modes as the machine boots. I'd like to see another connected window which allows me to view what would be in monochrome address space, 0xb0000 to 0xb7ffff.

    If such a thing doesn't exist, I'd like to be pointed in the right direction so I can write one. I just need access to that memory range in the virtual machine's memory, as well as a redirect of certain ports for reading/writing to that card's control registers, and then I can display the contents in a window myself. I have much experience developing on/with low-level Hercules graphics, including mouse pointers and flashing cursors in graphics mode (which is why I'm interested in having the ability to show what's in memory in a window--to support existing DOS-based apps I've developed over the years).

    Thanks for your help. :smileyhappy:
