I spoke a bit soon about the success of 1.3.3 on the 64-bit FC5 platform
after turning off NX. Dosemu runs fine, editors run fine, but the program
for which I actually NEED Dosemu does not. I have been using Generic Cadd
for 24 years as my primary design tool, and previous dosemus have
supported it essentially flawlessly. It crashes immediately with the
current installation, taking dosemu with it--ie it returns to the linux
shell prompt, or if started from an icon simply disappears.
The program can use XMS and/or EMS memory for drawings, but does not
itself run in protected mode. I have turned off both XMS and EMS access
with no change in behavior. It crashes with either the rudimentary
autoexec.bat and config.sys which comes with dosemu or my rather more
complicated one. It is configured normally to talk to a VESA- compatible
adapter (which has always worked) but behaves exactly the same way when
configured to talk to an ordinary VGA. It crashes with exactly the same
behavior when run from xdosemu or from dosemu from a console. I thought
perhaps there was some SELINUX interaction, but the behavior is the same
with any of the three modes of SELINUX including completely off. The only
hint of anything wrong in the boot.log file before the bomb is the
inability to open a TAP device (?) because of insufficient priviledge, but
the behavior is precisely the same when I set up dosemu and run as root
(the remark about the TAP device is no longer present in boot.log).
The program comes with a little executable to test the graphics video, and
it works fine, as does the configuration program. The first I believe is
significant and makes it unlikely that there is some hardware video
incompatibility.
I have no idea, of course, whether this is a 1.3.3 problem or a
64-bit vm86 problem or neither. In any case, the program works fine
on a variety of platforms under 1.2.2 and has done since I first
tried it under 1.0.something when I migrated to Linux several years ago.
The boot.log from the simplest setup run from root is quoted below.
Again, any help would be much appreciated; this is the last barrier
to moving to a 64-bit machine.
Thanks,
