Subject: DPMI errors on amd64, but not on i386
Date: Wed, 4 Feb 2009 20:24:46 +0000 (UTC) [thread overview]
Message-ID: <loom.20090204T201011-64@post.gmane.org> (raw)
I'm using dosemu 1.4.0.1 on Debian Lenny (compiled by myself as a 32 bit
executable). It works pretty well under a x86_32 2.6.26 kernel, running Windows
3.1 both in 286 & 386 mode, DJGPP, etc.
However, whenever I boot a x86_64 kernel, command.com and the rest of 16-bit
applications run fine, but Windows and DJGPP do not.
Windows only successfully boots every 100th time I launch it. Often, it just
shows "DPMI: Unhandheld Exception 0d"*. Sometimes it just hangs. After a
successful boot, it is also very buggy: Netscape (and most applications) tend to
crash due to page faults.
*Forcing 386 mode (win /d /3) results usually in DPMI Exception 06. Forcing 286
mode results in DPMI Exception 0d.
Often, "ERROR: SMALLOC: bad pointer passed to smfree()" appears on dosemu's
stderr.
I've tried the Debian packaged 1.4.0.0 amd64 binary, but the result is the same.
I've also tried vm86dev for x86_64; "runcom" does indeed work, 16-bit
applications are faster, but windows does not boot either.
