  Just wanted to cue in here and say that I experience a similar situation on an UPGRADE. Bob Meyer and I worked on it and eventually found: 
  1. BIOS (Motherboard NOT scsi) played a vital role in handing the boot process to scsi over ide 
  2. On the upgrade, the necessary init link/file was not passed to the boot strap. 
  This was determined through various steps but the most noticeable was when (after suspecting hardware failure of course :)) was on a fresh install everything worked and booted fine. There are only a handful of scsi adapter manufacturers (less than ide for sure), it's not inconceivable to think they put all the adapter drivers on the distros. 
  <-----------------------------------------------------------------------------snip-------------------------------------------------------------------------------------->
  Well this is what I think is happening with Joseph's Alpha box. First he was installing an OS other RedHat that could not have had the drivers needed to set up the raid scsi card right, secondly not using RedHat guaranties that either. But from what I understood it was booting not seeing the raid controller card? and did not see the drives. Also (if) the card was seen that does not mean that the drives where set up correctly. When I tried to install the OS saw the scsi controller but had a problem was the drives. The odds that in Joe's case of the raid scsi card not having drivers already available in the RedHat distro to install could be, but even if ( and I'm no expert the drives it not setup right ) the card is seen if the drives are not set just right (may or may not have) an influence as to weather the raid scsi card functions correctly. Or it could be a bad card? Who knows I've yet to see the box or an attempt to an install in action on the box in question. We'll find out in time the in's and out's of the beast.
  Well till future correspondence.

    On the subject of RedHat kernel having default support for a every SCSI adapter I disagree. We have a Dell server running RedHat 7.2, although I wasn't involved in the upgrade to a newer kernel (Dell provided), I know what happened through various emails between Dell and our other IT guy. They tried 2 stock RedHat kernels that did not work with our SCSI adapter, until finally the 3rd one did the trick. I was about to take over the project and just compile a kernel, but that would have voided our support w/ Dell & RedHat. 
      
    I'm not too sure about the hardware as this server (besides a Xeon) is in a remote office, but I did see the email traffic, and you could tell the Dell guys were stumped. ;)
