I don't get the option of passing parameters to the kernel 
on install from the LiveCD. However I'll keep it in mind 
that I can do it in principle.

the software raid was created by the winxp install (or the 
imaging process that created the hard disk). The sw raid is 
being done by Intel's sw raid drivers (at least according to 
some log file I saw)

I guessed I had to do something like that.

If I take the disk out and stick it in another machine I can 
see the partitions with fdisk, but not mount any of the 
partitions. I assume the disk is not partitioned the right 
way. Say I get the partitions off the sw raid machine 
(onto another disk), is there any hope of partitioning 
another disk on a second machine with fdisk and then dd'ing 
the partitions onto it and having the partitions readable 
etc on the 2nd machine? ie I assume the filesystem hasn't 
been changed by the Intel sw raid, but the partitioning has.

Thanks Joe
