I think I need a kernel where the scsi devices are compiled into the 
kernel, rather than using modules for scsi_mod and sd_mod, such as the 
SW71 scsi kernel.  Then at boot time I should see something like
sda:  sda1 as with the USB camera (usb-storage).  And I would need to set 
the scsi hard disk to some id not already in use (such as 1, 2, 3).

Do you have any idea what is going wrong with the scsi setup in my scsi 
computer?  Today nothing but the zip drive will work.

I have a scsi CD-RW device (which may be dying, today I got complaints 
about it from aic7xxx) and it is set to id=4.  The zip drive is id=5 (I 
try setting it to id=6 but it persists in being 5).  The scanner (which 
the card is not recognizing today) is set to 5 (I changed it to 6 but it 
still can't find it).  The Adaptec card is id 7.

Until today the controller was working with everything, except that the 
CD-burner was only burning 80% of any file to CD-ROM.

Then today for a while it was finding the zip drive and CD burner, but not 
the scanner.  I replaced the Microtek with an HP scanner and aic7xxx 
started spitting out error messages so I put back the Microtek and still 
got the same messages (something about parsing and id 4, which is the zip 
drive, this being the only scsi device that works now).  I will try 
removing the CD-burner (id 4) to see if the controller is happier.

I discovered this while trying to make a photocopy for a client (who 
showed up while I was in the middle of changing the video card).  Would a 
Trio3D video card mess up the scsi controller somehow, but only gradually 
do so?  It was working fine in my other scsi computer.

I read something about scsi devices interfering with each other sometimes.

Besides booting from scsi disk, another option is to use both IDE and scsi 
drive, and burn CDs after writing the file to the scsi drive first.  We 
have about 8 2GB scsi drives and even an external holder for one.

I could boot to linux on the IDE drive, with BL kernel, then insmod 
scsi_mod and sd_mod and aic7xxx, and mount the sda number aic7xxx 
finds.
