SUMMARY : E4500 Fast Data Access MMU Miss

Hi Friends

Thanks so much to all who replied regarding the problem I am having
with E4500 with Solaris 2.5.1.. Everything is OK now... Below is the
summary

*****************************************************************************
***************
The problem that you are facing in installing Solaris 2.6 on the new E3.5K
system has been discussed before the Solution of this problem is as given
below and I had tried it out and it worked perectly well.

the porblem is the 400MHz cpu with 8M ecache.
The kernel on Solaris 2.6 and 2.5.1's installation CD does not support this
kind of cpu when ecache > 4M, but with it can be supported by the latest
kernel patch. So I should set the ecache size to 4M on PROM level, then
install 2.6 and patches. See following steps by detail.( provided by
GOMATHINAYAGAM and Scott Clark )

1. Verify OBP version by typing .version at the ok prompt or use the
  /usr/sbin/prtconf -V command at the UNIX prompt.  If needed, upgrade to
  at least flash PROM version 3.2.21 using patch 103346-22 or greater.

2. ok setenv auto-boot? false

3. ok reset

4. ok limit-ecache-size

5. ok boot cdrom  (at least 2.5.1 HW 11/97 or 2.6 HW 3/98)

6. Install the OS but do not allow auto-reboot!
7. # init 0

8. ok reset (usually not needed with 2.6)

9. ok limit-ecache-size

10. ok boot

11. Make sure you have a network connection, FTP to sunsolve.sun.com and get
   latest kernel patch (minimum levels to support 400 mhz/8mb cache
listed):

   Solaris 2.5.1 --> 103640-27 and prtdiag patch 104595-08.
   Solaris 2.6   --> 105181-14

12. Change run level to single-user mode using init S.

13. Install patches from ftp download directory.

14. Reboot.
