Hello!
I'm trying to get doscmd going on FreeBSD-9.1/i386. It is an old
Pentium3 laptop. Whatever I do -- and I reduced my /etc/doscmdrc file to
just the two lines below:
boot A:
#assign A: -ro /home/mi/boot98sc.IMA 1440
#assign A: -ro /home/mi/winb600.IMA 1440
assign A: -ro /home/mi/winb500.IMA 1440
#assign B: /dev/fd0 1440
#assign C: /home/mi
-- the program crashes with SIGBUS promptly upon opening its X11-window:
% doscmd -b -x
ax=f7ec bx=c638 cx=0040 dx=ae7c
si=aa7c di=0100 sp=a5e0 bp=a5f8
cs=0033 ss=003b ds=003b es=003b
ip=6f52 eflags=10212
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
addb %al,(%bx+%si)
SIGBUS code 3, trapno: 9, err: 0
I tried compiling with "-O0 -g" -- and without any march-flags -- which
did not change a thing. I downloaded the boot-images from bootdisk.com
<http://www.bootdisk.com/bootdisk.htm>; -- and am currently trying to use
the DOS-5.0 image:
-rw-r--r-- 1 mi wheel 1474560 Nov 18 1999 /home/mi/winb500.IMA
Running with just the -b option (no -x), I get the program spinning --
eating up all CPU -- but never saying anything... Pressing Ctrl-T
results in: "Currently in the emulator" message. No crashes, but nothing
useful either.
Are there known problems? What am I missing? Please, advise. Thanks!
