This zip file contains V5.68 AlphaBIOS firmware and installation 
instructions for Digital AlphaStation 255 systems.

WARNING:  WITH THE MATERIALS INCLUDED IN THIS ZIP KIT, INSTALLING 
          ALPHABIOS IS AN IRREVERSABLE STEP.  YOU CANNOT EASILY 
          RESTORE THE SRM CONSOLE TO THE WORKSTATION.

This firmware should be installed if you plan to run Microsoft Windows
NT version 3.51 or later.  No release prior to Windows NT 3.51 is supported 
on the AlphaStation 255.

NOTE:    IF YOU ARE CURRENTLY RUNNING ALPHABIOS V5.10, YOU MUST USE
         FWUPDATE.EXE TO UPDATE THE FIRMWARE ON YOUR MACHINE.

Installing AlphaBIOS 5.68 is accomplished by copying the file fwupdate.exe 
onto a FAT-formatted floppy, then selecting "Upgrade AlphaBIOS" from the 
initial Setup screen.  Setup is entered by pressing F2 at the boot screen.
The machine will reboot into an APU-> prompt.  At this prompt type "update" 
and enter.  This application will update the SRM and the AlphaBIOS.  After
this application is fully completed.  Type "quit" and cycle power on the 
machine.  

If your AlphaStaion 255 is currently running Digital UNIX or OpenVMS, the
process of installing AlphaBIOS is somewhat more complicated.  You must 
first create a bootable floppy of AlphaBIOS, using the file fwupdate.exe.  
You can do this on an OpenVMS system or Digital UNIX, or, if you have 
a Alpha Windows NT system, you can use the included "makeboot" to create 
the floppy; see its "usage" message for invocation details.  Once you 
have created the bootable floppy, set the motherboard DIP switch pack 
switches Config0 and Config1 to OFF and ON, respectively, and power up 
the workstation; AlphaBIOS will boot from the floppy you have created.  
When that happens, proceed as in the third paragraph to complete the 
installation.
