7VRXP - WinXP install problem with IDE RAID = Mirror

I am helping a friend do a format/reinstall of XP-pro on his system. I
can't get Win Setup to recognize the RAID.

The RAID is configured with 2 WD-80GB disks in mirror configuration.
There is also a single WD-160GB USB disk (this is the only disk setup every
sees).

I made a floppy with the drivers from the MB CD.

During install:
Booting from XP CD
- if I dont load the drivers install just doesnt see the RAID.
- load driver & choose MBFasttrack driver setup just hangs after driver
loading phase
- (also tried SBFasttrack drivers hard crash-BSOD)

Also tried initiating install from windows (so it should use existing RAID
driver, right?)
- start install withing XP & specified install to drive C:\WinNT
- reboot start from XP setup system setup gets hard crash-BSOD.

Does anyone know what I'm doing wrong ?

Thanks,
Dale
