Promise Ultra66 PCI with SCSI Raid Controller

Posted on 2006-04-12

Hello experts,

I have an old Dell Poweredge 2400 with a single 40GB SCSI drive running WinAdvancedServer2K.  I am running out of space on that drive.  

I had a Promise Technology Ultra66 PCI card laying around here and found a great deal on a 300GB IDE drive.  So I'm trying to use this in my server.

Unfortunately, I'm an idiot when it comes to SCSI so it's not going easy for me.

I have the following SCSI devices installed (from system info):

Adaptec AIC-7880 PCI SCSI Controller
Dell PERC 2/Si RAID Controller
Promise Technology Inc. Ultra66 IDE Controller
Adaptec AHA-2940U2/U2W PCI SCSI Controller
D347PRT SCSI Controller

The IDE drive has not been formatted.  I attached it to the Ultra66 card right out of the box.

And finally, the symptoms.  

If I attach the IDE drive to one of the two IDE ports on the Ultra66 card, the computer boots as normal and I can see the Promise Technology card listed under SCSI devices in device manager.  Its status is listed as working correctly but I don't see the drive in computer management --> storage.

If I plug the IDE drive into the other IDE port on the Ultra66, I get a message before the OS loads saying something about reducing to Ultra33 because of a 40 pin ribbon cable and then it just goes to a blank screen and the OS doesn't load.

I'm assuming the second scenario is because the PC is trying to load an OS from the IDE drive.

Can you tell me step-by-step what I need to do to get this working (if it's even possible at all)?

Any help will be GREATLY appreciated.

    Does the promise have a rom chip on so that you can access it before windows loads up to configure it ,like the scsi controller would have.
    If so you could check if the drive is detected ,Also make sure that any other Ide channels have been disabled in the bios and that you are using an 80-Wire, 40-Pin Ide Cable .

    Hello f-king.  Thanks for the response.

    Although the boot screens show that the Promise is either loading it's BIOS or not (depending on which IDE port the drive is connected to), there is no key sequence listed (like CTRL-A as is the case with the other SCSI devices) to configure it.

    It either loads and then the PC screen goes blank, or it states that it isn't loading the BIOS.

    I'm going to try an 80 wire cable.  The drive came with a 40 wire.  I'll let you know if that makes a difference.

    Also, I have changed the jumpers on my drive to limit it to 32GB.  I did this because it looks like the Ultra66 may not support a 300GB drive.

    I added the 80 wire IDE cable to no avail.

    OK, back to scratch.  The boot sequence is determined in the BIOS, not the SCSI controller.  So you can go into BIOS and decide to boot from IDE or SCSI, and IF SCSI, then the SCSI BIOS determine how to boot.  Starter -- clone the boot OS from the SCSI to the IDE drive.  You should be able to boot from either disk array if need be.  If you copy SCSI setup to IDE and not boot, first set boot device in BIOS as IDE, then insert windows CD, and boot from it, then recovery console, then Fixboot C: -- assuming IDE is boot.

    When you get system to bot from either SCSI or IDE, now you inderstand how BIOS settings are crucial.  Once you get system to boot from either SCSI or IDE depending on BIOS settings, what more is problem?

    Didn´t the promise come with a bootable diskette or cd to configure it ?

    Also got to the promise website and download the latest bios for the card

    Select ultra66 and then bios and download the file then follow instructions ,it could fix that drive limit problem if it´s the case.

    Promise Technology Inc. Ultra66 IDE Controller + 300 gig drive = not usable

    The 66 Ultra supports up to 137 gigs,you need the TX 133 to see the 300.

    I downloaded and installed the BIOS for the Ultra66.  Now I get fatal kernel errors from my other controller cards.

    I gave up and took a bat to the poweredge ala office space.

    I put together another server sans SCSI from the mountains of junk in my attic.

    f-king gets an A for effort.
