I'm using a Dell Optiplex GX270 PC with a 2.8 GhZ P4 (no HT) with 1 GB Ram, Intel Integrated Graphics (96MB), integrated sound, and Win XP Pro SP2. The game I'm attempting to run in DOSBox 0.65 is called "Lost in Forest" (More into at http://users.student.lth.se/e96pd/Losteng.html). I have it installed in C:\LIF. I'm new to DosBox, so I used the "Pictorial Guide to DoxBox" in the DoxBox Guides Forum. Based on the instructions here, in the DOSBox Wiki, and in the ReadMe file, I typed the following:

mount C C:\LIF

C:

(I didn't type "cd LIF" because C:\LIF is already mounted. When I do, it says "Unable to change to: LIF")

Then, I typed in the executable file of the game (ol2.exe) and pressed Enter. Afterwards, I recieved the following error message:

Load error: no DPMI - Get csdpmi*b.zip

I'm not sure what this means. I've made sure all the files in the LIF folder are Read Only, but I still get this message.

I would appreciate anyone's help with this issue.

Thanks, I followed your suggestion and the game runs. However, it appears very small inside the DOSBox window. It's also very slow. What can I do to change the resolution and speed up the game?

Thanks, fullscreen helps with the size/resolution issue. However, I'm confused about how to change the cycles/core in dosbox.conf; the ReadMe isn't very clear on how to do this (as I mentioned, I'm new to DOSBox). Pressing Ctrl-F12 repeatedly helps speed up the game, but it's still very slow and DOSBox has repeatedly shut down during game play. What can I do to fix this?

Thanks for your help!

Thanks--I followed your suggestions of setting core=dynamic, cycles=auto, and nosound=true in the dosbox.conf file, and the game is way faster. However, after I got to a certain point (farther than I have ever gotten without a crash), I received a "Page Error" message. Attached is a screenshot containing the error message.

> nosound=true

This only disables the sound output, not the soundblaster emulation
itself (this would be sbtype=none instead of sbtype=sb16).

About the crash: don't know, real mode callback doesn't sount too
good, maybe use loadfix before starting the game.

I set sbtype=sb16 to sbtype=none, and used loadfix to allocate the default 64kb of RAM before starting "Lost in Forest" the next time. This time, instead of getting to a certain point and then recieving the "Page Fault" error, the game crashed as it did before (the DOSBox screen first went black, and then DOSBox shut down).

Any other ideas on how to fix this?
