Weird booting / re-booting problem

[Bradley Miller]

Ok -- this PC followed me home last night . . . (no wonder my electric
meter looks like a car odometer).  Anyway, I decide "hmm, a 2 gig drive and
a 12 gig, let's play with Trustix install.  It's a P200 with 32 mb of
memory -- an old HP Vector PC.  Overall a nice little box.   I started
initially to do a Mandrake 8.2 install, but decided that a new server box
would be a better idea.  I installed Trustix with no problems.  Then when I
get to the Lilo screen I can boot to Linux or DOS (which isn't working, but
I was just trying that out).   Once it goes into Linux it says it's booting
and then it restarts the PC.  Very strange . . . any suggestions on
tracking down problem?
