Finding Home DIR's of programs (dosbox).
 

I installed DosBox with yum. It works but I do not know where it is on the hard drive? Folder path?

try whereis or slocate (slocate you may need to run updatedb first)

whereis dosbox
dosbox: /usr/bin/dosbox /usr/share/man/man1/dosbox.1.gz

Wow ok, I guess that works. Thanks.

Now I am wondering, Does DosBox need a FAT 32 or 16 partition to work on a linux system?

for that i would look at man dosbox or the docs on the website for the app. I've never used it so i'm not sure

Nope.
Whatever file system you have linux installed on is fine.
From the dos programs it runs the file system will appear as virtual FAT partitions.

It will map a certain folder in your linux system to be the c:\ drive.

OK good, because i would hate to resize my partitions.
I am able to mount my home dir(mount c /home).

Thanks for the help.
