[rock-user] Install in stage 2 fails -- /mnt_source does not mount

Hello, 

This is my first time installing a 2.0 Rock distribution and I'm using the drock iso's. I burned the iso 
images and when I go through the install process, I start to load the Stage 2 image file, but 
get the following messages:

<27> "date" "time" insmod: insmod: /lib/modules/2.4.25_rock/kernel/fs/minix/minix.o
<27> "date" "time" insmod: insmod: minix failed
          can't mount /mnt_source: Invalid argument

Then it tries to extract the 2nd stage image file, but fails, since it can't find
the image file, since /mnt_source was never was mounted.

I was installing on a Inspiron 3500 laptop with 128 MB of memory and a 
4GB disk. But, also tried a spare Dell desktop with the same result.

Any suggestions?
