Problem Description: When installing 4.0.3sr from tape onto a 4/490 
  with 6MB/s IPI drives, the installation fails. 

INSTALL: 
  
    1. If you need to install 4.0.3sk on a 6MB/s drive you need to use the 
       4.1_PSR_A tape to load the miniroot and adjust the mount points 
       appropriately. In addition you will need the new format.dat entries
       supplied in this patch for the new drive.

       After you have installed the system you should reboot it and install
       the format.dat from the patch tape.

       mv /etc/format.dat /etc/format.dat.orig
       cp etc/format.dat /etc/format.dat



    2. If you need to install 4.0.3sr follow the same procedure as above
       and optionally do the following after SunOs has come up:

       cp 4.0.3sr/sun4/id.o /sys/sun4/OBJ        
       cp 4.0.3sr/sun4/is.o /sys/sun4/OBJ        
       cp 4.0.3sr/sun4/ipi.o /sys/sun4/OBJ        

       Make a new kernel, install it and reboot the machine.  This new IPI
       driver contains some fixes for minor problems found after 4.0.3SR was
       shipped.
