installing with raid array

[whaaa?]

hello, i've learned a few things since i tried to resolve this problem.

1) My hda and hdb are cd rom drives
2) My raid array (consisting of 2 drives) resides in hde and hdg
3) I can't partition or write to either of these drives directly for fear of losing the raid array.

However, i am determined to get this working on the nf7 mobo i've got

any suggestions would be appreciated
