This is indeed a treasure trove of material.
Does anyone know where to find the user manuals and binary files?

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=localti
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 Jim
Thanks again. My problem is that I have assembler source code from 40
years that occupies about 680Mb that needs to reside on one drive in
order to assemble. Then there are the application programs. All this
currently resides on an ancient XP machine. I have stayed with Lubuntu

Hi Jerome
My original question was about the maximum size of access directory. It
appears to be about 512Mb. FreeDos will not run under QEMU if this size
is exceeded. My image file was 200Mb. I have removed KVM and QEMU and
had planned to reinstall with a 2G image as you suggest. This being the
Hi All
Some feedback. Creating a 2G image allowed me to assemble source code
correctly. The only penalty being speed. About 6 to 11 times slower than
running DOS under XP.
I mounted the image and copied source files from backup directory to
mounted C: drive.

QEMU runs successfully on my Linux installation using the display option
sdl. eg. "-display sdl"
If I use "-display gtk", I get the following error "qemu-system-i386:

Anyone know what this means and how to fix it?

Robocopy for Windows has this ability.

Hi All
It appears that if a directory exists with the same name as the file
one is searching for, the directory listing is terminated early without
error.
I was searching for a files named "Q" with no extension. I used the
commands "DIR Q /S /B" and "DIR Q. /S /B", but it only revealed files
most directory names don't have extensions, this only picks out
the directory names (and of course, any files without extensions, but
those are rare), so that should find the q directory for you with
little to no trouble.

Hi Eric
I think the issue is more complicated/ subtle than I first thought. If
you create the structure I showed, you will be able to reproduce the
problem. Two other FreeDos respondents were able to reproduce the
problem. I was perplexed as to why I could not find files that I knew

As per Tom's request, below is a short batch file to show the issue.
It appears that the DIR command prematurely terminates it's listing
without error if a directory bearing the same name is encountered.
As I understand it, the DIR command should make no distinction between

Thanks Jim and Eric for your replies. On DOSEMU2, FreeDos's MEM command

Hi Eric
Times are just rough ballpark figures for comparison and specific to one
of my primary applications, a command line assembler. In this test case,
the assembly code consists of about 150 modules (files) and amounts to
slightly over 22K lines. Timing is done using 4DOS's TIMER command. I
Hi Tom
I think the emulation speeds achieved by both QEMU and DOSEMU2 are
excellent. In this instance whether it takes 0.2 second or 1.5 seconds
is really irrelevant.
As an aside, when I recently added an SSD to my HP notebook, year 2006
vintage, only a small improvement in speed was gained, s
