 You need the linux fdisk to set the partition id flag for Linux/Minix.
DOS will set up the partitions for you, but will flag them for DOS.
You will need to change your Linux partition flags to 81/82/83, depending
on your usage. Here's what mine looks like: (I just love cut 'n paste! ;-) )

 Hope this helps clear it up for you - I messed up my disk several times
when I was first putting up Linux.
