Hi, i did actually kind of get the card's working together but ran into another problem. when i boot with ide=nodma and then turn on dma manually on all the other cards / board chipset etc... they all function fine then i can only turn the dma up to ATA/100 if i set it to ata/133 it will cause the errors. I assume this is something todo with the promise bois not setting up the 3rd card at boot time. It only shows drive listing for 2 of the 3 cards. Unfortunatly this generated another problem. When read from both drives at the same time it functions normally and see resonable performance. When i attempt to write to both drives it will cause the machine to lockup.
