So, AFAIK atm, DOSbox is complaining about not having some graph library

No, the application's library (BGI) is complaining it either isn't initialized (missing init call) or can't initialize because it doesn't find the driver files (egavga.bgi or how it's called).

I see.... so what I have to do in order to make the said file visible to the app?

PS: Forgot to tell you, this used to run in a machine dual booting DOS and win98SE at the time. Dunno if it is relevant but I'll post it nontheless.

EDIT: found the EGAVGA.BGI file lurking around and now I don't have the initgraph error! Still now I am getting a "TCB not found" error (I think this is now something related to the app itself and it's not a generic error, I'll look around to see what it is....)

Did you install the app from within dosbox? When you didn't it might expect things to be at some path that doesn't match anymore with your mountings (e.g. If you mount the apps folder as c but it expects to be in c:/appname/)

indeed you can be right STILL there is a problem here.

The app was installed from a floppy drive. I do have one of those çying around but how do I map that drive to DOSbox ?

PS: mounted the folder with c directory and I am closer ro get the result!!!!!

Now it tells me that is missing a font, I'll have to look around the app folder and see what font it is using

The readme tells you about mounting a floppy

alright i'll give a look into it later

EDIT: Found the floppy of the program but it seems that it doesn't work anymore... guess I am stuck with an installed program with missing parts :\

After a huge amount spent in this thingy I got it working!!

Found out that for some reason the program doesn´t fetch the libraries like he should anymore and just replicated stuff here and there and it works!

Now onto the 2nd question: can someone tell me how to map the lptp and com port to DOSbox?

For printing with DOSBox you may need to get HAL's Megabuild. Search the forum.

Just found the megabuild and installed - it seems that lptp emulation is working!

Still I found another issue... the program itself is segmentated in various exe accross a lot of folders, and, it seems that everytime I go to the main one and try to go one of the options (gas analisys for example), it just shut downs himself without saying much.

So the question is: is DOSbox able to emulate the various exe calls inside a program? I believe that the awnser for this question is yes, but still something's odd here....

PS:I even tried to get all files out of the folders and get all of them in the main one but got the same result....

Have you installed the program from within dosbox AND are you keeping the same mountings?
Other than that you need to be more precise, mountings, writing don EXACTLY what you are doing on dosbox prompt and what the results are

Like I said earlier, the floppy that had the program is not functioning anymore, so I cannot install it.

As for the mountings, I am using the standart "mount c" command to recreate the drive that used to have the program running (I've backed up that drive entirely in my new system, mounting it to make sure the c:\ defualt path was working).

About the outputs, nothing is clear.... the program is run inside Dbox and then when I select some options it just returns to the prompt without saying anything.

Didn't see the edit. Good luck, maybe if you can provide more information someone else takes the time to figure it out. I'm out of here.
