I installed one of these monsters for a customer recently
as a system disk.
The Maxtor 8760 looks like an RZ56  in configuration.
Use the following script to install it.  *Do not*  pick the 
"Advanced Installation" option at  any point during the installation.
Also, make sure all are devices are made (MAKEDEV), use 'newfs'
and 'mount' to make any new file system, and edit /etc/fstab approriately 
to reflect the 'fsck' sequence during boot.  I am in a hurry and I can't
write a very detailed note.  Send me mail if you run into any unusual
problems.

*Remember*:  This is a 'free' suggestion - it does not supercede regular
                        support channels available from Digital.  

The following is the script:

	Patching the Installation Procedure for RZ56/Maxtor 8760 

		Ultrix WS V2.* (RISC)
		Ultrix-32 V3.1 (RISC)
	
(On TK50 installations, wait for the tape to rewind completely
 before proceeding)

You may not even need a special disktab.
