They told me that 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 and get
    latest kernel patch (minimum levels to support 400 mhz/8mb cache

    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.

There are some documents talked about this problem on sunsolve.

My original question :

Hi gurus,

I want to install 2.6 on a new E3500 machine, but it can not boot from 2.6's
cd (98/5).
It can boot from 2.7's cd which include in this machine.
There are two 400MHz CPUs and each has 8M ECache.
Does anyone met this before?
any suggestion will be appreciated.
