How should I connect my hard drives and other storage devices on my KT7-RAID?
ABIT advise that hard drives should be connected to the HPT370 controller (IDE 3 and 4), which supports ATA 33, 66 and 100.
ATAPI drives such as CDROM, DVD, CD-RW, Zip, LS120 and tape devices should be connected to IDE 1 and 2, as should additional disks when IDE 3 and 4 are fully occupied. CD-DVD and CD-RW devices may perform best when each is connected as IDE Master. So, if you have a CD-DVD and a CD-RW, connect each one as the Master on IDE 1 and 2, and use slaves for other devices like the LS120, tape, Zip, etc. Ensure the DMA-box is checked for your CD device properties under System Properties. Set the BIOS for the four primary IDE channels to AUTO to see your ATAPI devices correctly on the IDE 1 and 2 ports.
For RAID-0 the two disks it is advisable to place them on separate Highpoint IDE controllers, as on my machine, using the disks as Master/Slave on the same controller resulted in very little speed increase. Other people achieve good speed improvements whether or not the disks are on separate controllers. You may wish to experiment - you don't need to reinstall anything if you simply move a disk to the other Highpoint controller - the Highpoint BIOS will successfully detect this.
Note that despite Highpoint documentation to the contrary, it appears that many users are unable to successfully use ATAPI devices if they are connected to the HPT370 controller (IDE 3 and 4).
One user wrote that If you want to use two disks in a RAID in a Master/Master configuration, you cannot share an IRQ with the Highpoint controller, it will just lock. If you must share an IRQ with the controller then the only way to get a stable system is put the drives in the RAID on the same channel as Master/Slave.
