I have not yet set up large file support. But you could try it and see...

First, see if you have more than 2 GB available space on the drive.
Then try this:
dd if=/dev/zero of=big_file_test bs=1024 count=2200000

If all is well, that should take a few minutes and leave you with
a file a little over 2 GB.

If dd exits with an error, then your system is not set up for large files.
remove big_file_test when done, of course.

I don't have Mandrake, don't know what they do by default, but you may have to:
1) compile a new kernel with large file support (look in the filesystem options
during make xconfig or make menuconfig)
2) make a new filesystem with large file support (read man mke2fs).
I think you need at least version 1.20 of mke2fs.

hope that helps,
