Greetings,

My system is an ASUS p55tp4xe w/SC200 ncr scsi.  I have a seagate hawk
1.05 gb disk as sd0 and a Micropolis 3243-mz 4.095 gb disk as sd1. 

I can create a working 2.1.0 system only so long as I use the 4gb disk as
a single giant partition.  I have done this and the system comes up and is
happy with the 4gb drive.  I am using 4095/64/32 for the disk geometry on
the micropolis, as suggested by the installation program. 

However, when I use the installation procedure to partition and label the
4gb disk into multiple slices, I run into trouble as soon as I continue
with the part of the installation which actually writes the labels to the
disks (I am NOT using 'w' from within FDISK!): 

	1) The installation panics and complains that the init process has 
           died.  On the debugging screen I get a message similar this:
           (I couldn't find a way to stop the auto-reboot and preserve the
           screen for very long so the numbers might be a bit off.)

		ncr?: scatter/gather failed (residue=209687000)
                 sd1: oops not queued
                 init died


        2) On the next invocation of the install utility, booted from
           floppy, I see the following in the debug screen before I 
           actively do anything:

		 sds1: raw partition size != slice size
		 sds1: start 32, end 8386559, size 8386528
               sdsi1c: start 32, end 65535, size 65504

I haven't tried to fdisk/label the big disk outside of the installation 
program, is there a chance that might work better?  Any suggestions?  

-Chris
