Question Re: Promise Ultra 100 controler on ABIT BH6 MoBo

I do not believe that the BH6 rev 1.0 supports UltraDMA of any kind.
This being the case, I would like to use a Promise ULTRA 100 IDE controler card and hook up the hard drives to it.
This will be a Win98/Win2k duel boot system as follows:
The Win98 drive will be a Samsung / 6.5gb / UDMA 33
The Win2k drive will be a Maxtor / 40gb / UDMA 66.
Can I use the Promise card for the boot drive or drives instead of the Primary IDE channel on the MoBo?

yes indeed & if you're not going to be using one or both of the m/board's ide channel then you can disable it saving yourself 1 irq/channel!
do remember to set the boot order in bios to scsi before ide as the card is seen as a scsi device. 🙂
 
DN,

your BH6 r1.0 should also be ATA33-ready..

How would I tell if it supports ATA33 or not, the product info does not say. It only states that it has to IDE channels.
 
Ja, Device Manger sez BH6 rev 1 IDE Channel mode is Ultra DMA. Caveat about auxillary controllers is ya won't be able to spin-down the HDD's.

Yes, of course, look in device manager. I should have thought of that. I guess I was having another one of those all to common "Senior Moments".


Auric,

Caveat about auxilliary controllers is ya won't be able to spin-down the HDD's.

Whatto you mean?
 
Windows power management will not have any control over the drives run on the add-in controller. Confirm with Promise to be sure their drivers do not have some integration but as far as I know that is still the case. To me, it is an important feature and the reason I never used one with my ol' mobo.

Got it. That is a good point.

I also checked device manager and found that I had not turned on DMA for the main Hard Drive.
This did bring the speed from 9mb/s up to 27mb/s.

I believe that I will take your advice and leave the Hard Drives on the MoBo controler and put the CD-Rom, CD-RW, or the Zip100 on the add on controler.

Thanks for the heads up on this issue.

W00t! Free hitherto undiscovered speed!

Sorry to be the bearer of bad news but there is another limitation of the add-on controllers, that being they only run HDD's. Again, that is as far as I know from earlier Promise models.

This may have been true of earlier models but the Ultra 100 does support ATAPI devices. In fact, I am running my CD-RW on one in my other system (the one I am posting this message with) right now.

Thanks for the warning though. If this were true, it would definately be the kind of thing that I would want to know.
