Dear List -
I am having problems writing and performing bunzip on the
image of FreeDOS
{If this is not a "Good Question", please tell me how to
improve it.}
Here is what I did:
1] Plugged and unplugged the USB stick /var/log/messages
told me it was /dev/sdf
2] Downloaded the image:
ethan@rosenberg:~$ ls -lt Downloads|more
total 1434800
-rw-r--r-- 1 ethan ethan 32505856 Mar 20 14:02

3] Attempted a dd

I can't find the file. What have I done wrong?

Should I format the stkick FAT16?

First off, the boot image is a .bz2 file. That is a bzip2
compressed file. You need to unzip it to make it into an image
file.
From reading the comments on the page for the USB download, it
appears that you should dd the image to /dev/sdf. Apparently
it contains the MBR and a partition table. Next you can mount
the USB key partition 1 (/dev/sdf1) somewhere and copy the
bios update program and the updated bios file to it. Finally,
reboot to the USB key and run the bios update program.

Thanks.
I'm doing something wrong and can’t figure it out.

Where is my error?
Ethan
If I am understanding what you are trying to do then...
If the usbstick is /dev/sdf then the output file of the dd command
should be /dev/sdf (the unmounted device) NOT
/media/usbstick/FreeDOS-1.1-USB-Boot.img (a file in the filesystem
on the mounted device). The image IS a filesystem, which should
be written to the device not to a file IN a filesystem ON the
device
