I have to set up a dosemu environment for a clipper 5.3 program, using the DOS/16M dos extender. The problem is that the program can't use the memory above 1 MB. According to the docs, the program SHOULD use DPMI, and the logs show that it is actually doing some DPMI calls (GetFreeMem, Alloc, etc), but it is not using as much memory as DPMI offers.
Here are my memory settings:
$_xms = (16384) # in Kbyte $_ems = (off) # in Kbyte (couldn't make the program use it) $_ems_frame = (0xE000) $_dpmi = (16384) # in Kbyte $_dosmem = (640) # in Kbyte, <= 640
I have a simple Clipper program that displays the memory available to the program (251k gzippped), I can email to anyone willing to debug a little.
Other programs using DPMI (like Turbo Pascal 7.0's tpx.exe) are seeing and using correctly all DPMI memory available.
My system configuration:
Celeron 366, 128 MB RAM, ~100 MB swap Debian 3.0r1 dosemu 1.1.5, compiled from sources
compiletime-settings: config { experimental off sbemu off mitshm off vidmode off x off net off dodebug off linkstatic off cpuemu off aspi off svgalib off plugin_keyboard on plugin_kbd_unicode off plugin_extra_charsets off plugin_term off plugin_slang off plugin_translate off plugin_coopthreads on plugin_commands on plugin_demo off target_cpu auto prefix /usr/local bindir ${prefix}/bin sysconfdir /etc/dosemu datadir ${prefix}/share mandir ${prefix}/man docdir ${datadir}/doc/dosemu syshdimagedir /var/lib/dosemu x11fontdir ${datadir}/dosemu/Xfonts fdtarball none }
Clipper version 5.3b Intl. (338) DOS/16M version 6.01
Can anyone help me?
Thanks, Zsolt
