KT7RAID only supports UDMA33 with the onboard IDE ports?

I was looking at getting the KT7RAID and noticed that it only support UDMA33 with the onboard IDE ports (Non High Point ports)? I thought they supported up to 66?

I have a Western Digital Expert 7200rpm UDMA66 18gig and Seagate Barracuda ATA 7200 UDMA66 20gig. How much faster will they run on the highpoint controller UDMA66 versus the KT133 UDMA66?

Thanks

btw: If I have an existing hard drive with Win2k on it and I put it on the Highpoint controller, what do I have to install to get it automatically boot without getting a "No operating system found" error message?
 
Kt133 natively supports udam33/ata66 - Maybe you misread - older slower devices udma devices should be placed on the primary/secondary ide controllers and not the tertiary/quarternary Raid ports
 
If you have only one hard drive, I would put it on the Non Raid IDE ports and disable those extra ports (hpt370) in the bios to have a faster boot up time. I believe you will only see performance gains if running RAID - striped HD's or if the HD supports ATA100
 
Nope I didn't misread it. Read about 3/4 of the way down:

I current have two hard drives, a dvdrom, and a cdr. I was planning on each having its own channel, for optimal throughput. The two hard drives on the Highpoint controller and the other drives running on the KT133 chipset channels.

btw: I was asking about the "No operating system found" error because my brother has a Gigabyte board with a Highpoint controller onboard and he had to go through a special procedure when he formatted and reinstalled Win98. What do I need to install to get it to work with an existing hard drive with OS?
 
Well, technically it should state ATA 33/66. However, I've found that a IBM 75GXP 30GB drive attached to the onboard IDE port of my KT7 (non-RAID) when benched with HDTach 2.61 has a burst speed of 38.6MB/sec consistently. When the 75GXP is attached to a Promise Ultra100 controller in the KT7, the burst rate is off the scale. Maybe they're being honest about practical throughput 🙂?
 
Juggernot,
I never noticed that at the abit website until you pointed that out.
Anyways - The Kt7-KT&-Raid manual lists under Multi IO finctions
tWO cANNELS OF bUS maSTER ide poRTS sUPPORTING UP TO 4 udma 33/66 DEVICES
tWO cANNELS OF bUS maSTER ide poRTS sUPPORTING UP TO 4 udma ATA-100 DEVICES (raid only)

As far as NO OS error- I have always done fresh installs on my KT7-Raid and Bp-6 so Im not sure but MAke sure you have latest Bios for MB/HPT or install the HD w/OS on the non Hpt ide ports, install the drivers for the Hpt controller, then move the HD over to the Hpt based IDE ports - making sure you set in the MB bios the correct boot sequence for each respective ide port.

When you say &quot;raid only&quot; do you mean a single drive can't be used on each channel seperately? I was under the impression that a raid controller can be used either way, no? I wasn't planning on utilizing the raid feature until I get two identical drives.
 
Does anyone know of a thread, web page, or have their own testing comparing a RAID setup vs a Non-RAID setup of identical hardware? I am getting tired of instability of my KT7-RAID (which I am using two IBM 75GXP 15GB drives) on the RAID controller and am considering running without RAID. ANyone have comparisons?
