i have notes for the following

SS10 simm locations:
1       J0201   (must be 64m if mixing 16's and 64's)
2       J0304
3       J0203
4       J0302
5       J0303
6       J0301
7       J0305
8       J0202

DETAIL DESCRIPTION FOR A SS10SX and SS20 (Netra /20, Netra s20, Netra
i600, Netra i625):
The layout below is from "Sun Field Engineer Handbook" dated 12/5/97.
The layout is present in order as found on the motherboard when it is
viewed with its front towards you, reading from the top down (from back
to front).  Each row represents a SIMM slot and shows its slick screen
label, its install order, its memory address range.

J0201    0th     00000000-03ffffff
J0202    2nd     08000000-0bffffff
J0203    5th     14000000-17ffffff
J0301    3rd     0c000000-0fffffff
J0302    6th     18000000-1bffffff
J0303    1st     04000000-07ffffff
J0304    7th     1c000000-1fffffff
J0305    4th     10000000-13ffffff


  The SPARC 5 memory is aligned in the following manner.
  From your output it looks like the bad DIMM is in location
  J0303 as the MFAR address fall within that range.

J0403    7th     0e000000-0fffffff
J0402    6th     0c000000-0dffffff
J0401    5th     0a000000-0bffffff
J0400    4th     08000000-09ffffff
J0303    3rd     06000000-07ffffff

MFSR=81802860 MFAR=645c078
        thru
MFSR=81802860 MFAR=78b3220

J0302    2nd     04000000-05ffffff
J0301    1st     02000000-03ffffff
J0300    0th     00000000-01ffffff
