  The target device now contains an empty RISCiX filesystem. To make the 
  device 'bootable' it is necessary to....

  1. Type 'halt'
  2. Replace RISCOS files in the SCSIFS section.
     Minimum required !Boot, !RISCiX, App1, and setcmos.
  3. Change Option on drive to *Opt 4,2
  4. Boot by typing...
     *boot vmunix fd0(0,0) sd0(0,1)
     using the kernel floppy disc and then insert the 'mkboot' floppy when
     prompted.
  5. run 'mksystem' when prompted.

cat << USE_SCSIDM

 This disc contains scsidm and newfs which could be used on their own.
 The disk does not contain a disktab file. It uses scsidm to generate one;
 therfore ensure the diskette is not write protected when using it.

 A script exists on this disc called 'mknewfs' which will run both scsidm 
 and newfs and will automate some of the process of setting up a scsi disc.
 To use this script type 'mknewfs' at the # prompt.  It will run scsidm
 on /dev/rsd0h.  After identifying the drive successfully type 'format', if
 this is required.  When formatting is complete type 'section' and say 'yes'
 to include RISCiX partitions. Now enter the section size required. Then
 type 'partition 0,1' and define partitions 0 for root and 1 for swap by
 entering the partition sizes.
 Then type 'quit'.
