Dang .. HP used to have a _lot_ of HP X terminal software available for 
FTP on (a.k.a., but I just checked 
there, and they seem to have drastically changed the nature of that 
server :-/  (real drag ... it used to be quite useful...)

Unforunately, HP, in their infinite wisdom, didn't provide a "boot into 
single-user mode" option (of course, the system v notion of runlevels 
that HP-UX used makes single-user somewhat ill-defined...)  I'm not sure 
of a way to get it to boot up into single-user short of making the fsck 
fail... You might try sending a SIGQUIT or SIGINTR to fsck (or some other 
important utility) during the boot process...

Other than that, it's been a _long_ time since I've really used HP-UX (I 
was quite happy when the University pretty much dumped it for 
NetBSD/hp300 :-), so I'm not sure I have any more suggestions...

Good luck!
