strange "3FA:" prompt on toshiba tecra boot

[Mark Phillips <mark@ist.flinders.edu.au>]

My friend's Toshiba Tecra 8000 laptop won't boot.  Previously it has
booted fine, but currently all it comes up with is a

3FA:

prompt.  Hitting return just causes this prompt to repeat itself.  It
doesn't even seem to get to lilo.  I can't think what is wrong, and I
couldn't find anything in the archives on it.

Any ideas anyone?

Thanks,

Mark.
