The operating system on the specified device is used to
start the workstation.
• To interact with the Initial System Loader (ISL) before
booting the workstation, type the following at the
prompt:
boot <device>
You are prompted:
Interact with ISL (Y, N, Q) >
Answering yes (y) causes the ISL to be loaded from the

ISL>
ISL is the program that actually controls the loading of
the operating system. By interacting with ISL, you can
choose to load an alternate version of the HP-UX oper-
ating system.
For example, if the usual kernel (/hp-ux for 9.05 and
/stand/vmunix for 10.0) on the root disk (fwscsi.6.0)
has become corrupted, boot the workstation from the
backup kernel (/SYSBCKUP for 9.05, and
/stand/vmunix.prev for 10.0) by typing the following
at the ISL> prompt:
hpux /SYSBCKUP (for 9.05)
hpux /stand/vmunix.prev (for 10.0)
• To find the location of the bootable operating systems on
the various media in the file system, use the search com-
mand.
