Look at any documentation that came with your motherboard and/or the manufacturer's website. The driver pack I compiled (theoretically) supports the onboard Promise 378 controller, so you should be OK on that end assuming you followed directions correctly. If the drivers are integrated correctly, you will see them on controller fasttx2k. If you have the drives attached to the Intel SATA controller, you can NOT do JBOD as it only supports RAID 0/1/0+1 modes. Also, there's really no performance gain from running in JBOD mode. The only advantage you get from it is that the drives are seen as one big drive rather than as separate drives. Again, IF YOU DON'T HAVE MATCHING DRIVES, YOU ARE PRETTY MUCH GUARANTEED TO SEE NO PERFORMANCE GAIN FROM RUNNING IN RAID.
