- Welcome to the 286smx Demo!
-
- DDEMOLT is our standard DOSdemo modified to run in protected mode and
- to use the facilities provided by the Phar Lap 286|DOS Extender. The file,
- 286CORE.C, shows the use of PHAPI calls and other changes to support
- protected mode. Compare it to the real mode file, CORE.C. Both of these
- files are located in c:\smxdemo\286.
-
- If you wish to view the demo files now, you can exit to DOS (Ctrl-X).
- Otherwise, 286demo will run shortly after you are done viewing this file.
-
- Now that the demo files have been installed, you can run 286demo directly
- from your hard disk, if you wish, without going through rundemos again.
- Just type "run286 ddemolt". (run286 is a Phar Lap 286|DOS Extender file.)
-
- This demo will not run without 286|DOS. Also there must not be a DPMI
- server present (e.g. 386MAX or MS-Windows.) It may be necessary to remove
- all memory managers, as well.
-
- If run from floppy, the demo will run slowly. If run from hard disk it
- will run faster. This is because it is doing actual DOS file reads.
- (When running this demo under rundemos, it is being run from your hard
- disk.) While reads are being performed, the preempter task is randomly
- preempting.
-
- The first selector shown is the first selector value assigned to ddemo by
- RUN286. The low three bits are used for other purposes. Hence this value,
- 359, is actually the 44th selector (/8); it is for the LDT; and it shows
- that the application is running in ring 3 (lowest privilege level).
-
- smxProbe is linked into this demo. ^s will invoke it. For directions on
- how to use smxProbe, see the file PROBE.DOC.
-
- This particular version of DOSdemo was made with Microsoft C. 286smx also
- support Borland C.
-
- Note: The TEST.DAT file is needed by the ddemo. Do not erase or move it.
- Also, be sure to run DDEMOLT from its subdirectory.
