   linux 2.4.19 (linus, not ac)


steps taken to install:

As root:

1. In /root: dosemu-1.1.3.tgz, dpmi_sti4a.diff, patchset-1.1.3.7.tgz,
   dosemu-freedos-bin.tgz

2. # tar zxvf dosemu-1.1.3.tgz

3. # cd dosemu-1.1.3

4. # tar zxvf ../patchset-1.1.3.7.tgz

5. # sh tmp/do_patch

   This patches DOSEMU 1.1.3 to 1.1.3.7

10. # cp ../dosemu-freedos-bin.tgz .

11. # ./install_systemwide -fd dosemu-freedos-bin.tgz

Not possible, Linus is no longer maintains
the 2.4 kernels.
-ac is recommended for dosemu users as
Alan Cox kindly applied all the dosemu-
related patches in 2.4.19, while Marcelo
have done that only in 2.4.20-pre (and
not so kindly, I would say:)

Add "./default-configure -d" here.

Well, at first search your system logs
for Oopses as usual, however "core dumped"
makes sense, so you'll probably find none
there.
In that case run dosemu.bin under gdb
and provide a stack trace at the point of
a crash.

If you feel this is a dosemu's bug
(which is probably true as the core was
dumped), you can also fill in the bug
report at SourceForge BTS.
