Subject:   Problem with 2940 PCI + 4G SEAGATE ST15230N

I had strange problem with 2940+SEAGATE ST15230N:

I did try to make it boot device and did use SCSI address 0.

Newfs did produce a lot off error messages about some HARDWARE errors.

I had used same drive with SCSI address 2, so I did return it to address 2
and all did work fine! (Execpt - I cannot boot from that drive)

Questions:
1. How can the change of SCSI address from 2 to 0 cause hardware errors?
2. Why can=B4t I boot from that disk in address 2?
3. Why can't I boot even when I change the address back to 0?
4. Why does disk work fine in address 0 now, when I do not try to
   install sysmtem on it? I am booting from my old IBM 0664
   (in another 2940).

HW: Motherboard is Intel Zappa, I have 2 times AHA PCI 2940, one IBM
0664M1H, one ST15230, 32M RAM.

I did install 951005-SANP. Installing 2.0.5R on ST15230 in SCSI address 0
did produce very same hardware errors. I had only one 2940 in use when I
did the installation. Installed 951005-SNAP to the drive with SCSI=3D2.

If I did try to write Label in 951005-SNAP installation with W. It could
not newfs root partition ("could not make/mount root partition"). When I
did Q without W installation did go OK and it did newfs root.
