[comp.sys.sun] SCSI HELP REQUESTED FOR 105MB and MAXTOR 200MB SCSIS

Hi, I've got problems with two scsi disks.

First, with the standard 105MB shipped with the 4/60.  
I can format the drive just fine, and even make
filesystems and read the data, but I cannot boot
from the drive without it saying 'data access
violation.'  I do know how to use installboot,
but just in case, here's what I did:
  1) Mount /dev/rsd2a /mnt
  2) cd /usr/mdec
  3) installboot -vlt /mnt/boot bootsd /dev/rsd2a
(actaully 1) is mount /dev/sd2a /mnt).

Probabaly, knowing the jumper settings if
anyone's got them would be very helpful here.

Second, I've got a Maxtor LXT200S which keeps
getting errors of 'incomplete read'.  Also,
I'm using guessed-at drive parameters here,
butchered from a SUN 200MB disktab entry.
However, I CAN boot from this guy, but it'll
eventually give up after too many 'incomplete
read's.

Two things would be helpful here:
  1) a disktab entry
  2) proper jumper settings

Thanks very much for any help.
