Now my vga refresh problem went away, and all is well. Check out the following 2 screen dumps. One is a dump of the cooperative kernel. The other one a modified virtcode, to do nothing but print out a message. The cooperative one iterates just like on a real PC, screen updates and all. Yet another milestone in FreeMWare evolution. We can actually show screendumps of our progress. :^) BTW, I carried over some of the IO device emulation framework from bochs, so it will be easy to plug in emulation of other devices from bochs as well. Once the IO virtualization code in FreeMWare is working, it should plug in reasonably well. We can go beyond devices supported in bochs when needed, but they should provide us with a known quantity, and the BIOS in bochs can drive them. Will roll a tarball shortly. -Kevin
