Hi Jim
Thank you. I have few questions. What is the maximum size allowed for
the FreeDos image file? Can I resize my image file, currently 200Mb? Can
I create an additional virtual drive "D:" and mount it in the same way?
Re. Use of "sudo" When I tried to run QEMU with with the "-enable-kvm"
option, I received an error message of permission denied. I have since
tried without "sudo" and it now works? My Linux installation (Lubuntu
18.04) has also sustained damage since playing with QEMU. I receive an
error message window on the desktop after boot-up which simply says "
System Error" and provides two buttons of "Report" and "Cancel". No
other info. I'm guessing there is a log entry hiding somewhere?

I wrote the article, but I haven't used this QEMU feature for a long
time. I found that the "live" access to the folder could be
problematic (sometimes no problem .. typically slow .. crashed QEMU a
few times) but that was several years ago and the QEMU folks may have
fixed that issue by now.
Now, I use a virtual disk image for QEMU. After I shut down the
FreeDOS guest, I can "mount" the virtual disk as a non-privileged
Linux user with guestfstools, and manage files like I normally would.
If the image file is "$img" and the mount point is "$mnt" (such as
/tmp/freedos) then run this:
guestmount -a $img -m /dev/sda1 $mnt
And when you're done, you can unmount it with this:
guestunmount $mnt
Also: You don't have to run QEMU as root (with sudo). I never do.

Hi there
I need some help please. Does any one know how to get around the size
limitation of the access Linux folder when running FreeDos under QEMU?
The access folder is named "dosfiles" as in Jim Hall's article on
Opensource.
Running the command:-
sudo qemu-system-i386 -m 32 -rtc base=localtime -drive
file=dos.img,index=0,media=disk,format=raw -drive
file=fat:rw:dosfiles/,format=raw -boot order=c -display sdl -enable-kvm
Gives status message of:-
vvfat dosfiles/ chs 1024,16,63
And an error message is issued:-
qemu-system-i386: -drive file=fat:rw:dosfiles/,format=raw: Directory
does not fit in FAT16 (capacity 516.06 MB)
Removing files from the "dosfiles" directory allows FreeDos to run.
