Appendix D
D. Creating a System Disk From the PROM Monitor
This appendix describes how to create a system disk from an option disk and install an
operating system. It describes how to install a system disk on a system that does not
currently have a working system disk. It is used in these situations:
• The new disk has no formatting or partitioning information on it at all or the
partitioning is incorrect.
• It is an option disk that you must turn into a system disk.
To turn a disk into a system disk, you must have an IRIX system software release CD
availableand a CD-ROMdriveattachedtothe systemoravailableonthenetwork. If you
areusing aCD-ROM driveattached toa systemon the network, that system must be set
up as an installation server. See the IRIX Admin: Software Installation and Licensing guide
for instructions.
These instructions assume that the system disk is installed on controller 0 at drive
address 1. This is the standard location for workstations; the controller number is
system-specific on servers. Follow these steps:
1. Bring the system up into the System Maintenance menu.
2. Bring up the Command Monitor by choosing the item 5 onthe System Maintenance
menu.
3. Give the hinv command and use the CPU type to determine the version of
standalone fx that you need to invoke. For example, a system with an IP30
processor is an ARCS processor, so the version of standalone fx needed is
stand/fx.64.
4. Determine the controller anddrive address ofthe device that contains the copy offx
that you plan to use (a CD-ROM drive attached to the system or a CD-ROM drive
on a workstation on the network). For example, for a local CD-ROM drive, if hinv
reports that the CD-ROM drive on the system is scsi(1), cdrom(4), the controller is 1
and the driveaddress is 4.The remainder of this example usesthat device,although
your device may be different or may be located on a different workstation.
