Certainly, using the feature flags is a far more appropriate approach
than maintaining a list of CPU types known to work, and not at least
having a list of them would be (is?) VERY bad -- assuming, of course,
that the features needed *have* flags. Using the Linux-specific
information from /proc/cpuinfo may or may not be the best way to do it
(of course, the CPU-provided flags will not tell us things like
f00f_bug...), depending on whether we want dosemu to work on anything
but Linux (and on what other systems it works (or could easily be made
to work) on right now).
Unfortunately, I have no idea what CPU features dosemu actually
requires on x86_64...

Thompson <the_drbobo*earthlink.net> > Freedos-user <freedos-user*lists.sourceforge.net> When I run a fortran program producing a graph from Desktop (in Dosemu/Freedos), graph appers and all is well. When I attempt to run the same program from a virtual console. the screen goes dark until the graphics phase is ended, when it returns to normal. The graph is plotted in 640x480 resolution. The boot.log file shows VGA-BIOS-SEGMENT set to 0xc000 VGA-BIOS-Size set to 0x10000 ......................................... reserving 128Kb at 0xA0000 for 'v' (Video memory) ....................................................................... reserving 4Kb at 0xC0000 for 'V' (VGAEMU Video Bios) How do I display the graph (or write it to a file for later display)? Is there a mode command that should switch the display contents?
