PCI RAID card recognised but disks don't show - G4

[Clive Menzies <clive@clivemenzies.co.uk>]

Hi

I've got a PowerMac G4 QuickSilver (OpenFirmware 3) which I'm setting up 
as a file server.  Etch is installed on /dev/hda and is working fine.  I 
bought a PCI IDE2 card to add two additional 750Gb ide drives which I 
propose to configure as RAID1 using mdadm for /home.

However, the card is fairly cheap (fake raid) and whilst the the card 
appears to be recognised, the disks aren't.  I've tried different jumper 
settings on the disks (master/slave, cable select, master/master on 
different ide cables).

The card is made by Star Tech

I'd be grateful for any useful pointers.

Thanks
