Nah, it will eventually start, and from some googling, it appears I need to 
haul it up to the tv station & make use of the capacitor wizard I bought 
before I retired.  Bad caps in the PSU, they have to warm up before they work 
somewhere near right.  Which also explains the occasional odor of something 
hot in this little man cave that I haven't been able to run down.  That 
little $175 gizmo is the slickest thing for finding bad caps I've ever seen.  
In a busy shop, it will pay for itself the first week in troubleshooting time 
saved.

There is a grub installed on the first drive and the 4th drive, and I have 
been booting the 4th drive by copying its vmlinuz etc to the first drives 
boot partition but naming the 4th drives partitions as I can't get a 
chainload to work there either.  I did have it working to the 2nd drive for a 
while, booting Mint8-x64, but I did something to mint and it won't boot 
anymore, so I overwrote it with F12.  If it installed grub in /dev/sdb's MBR, 
I should be able to do this.  Unforch, I have not found a tool which can read 
the MBR and tell if it is.  dd of course can pull it, but I have NDI how to 
interpret that output.  The string 'GRUB' does exist in it, sstartiong at 
offset 0179, but that could be leftovers from the old mint install FAIK.

Which of course limits me to a verse of grub.conf for each kernel installed, 
and easy thing to do with mandriva since they default the boot names to 
softlinks from vmlinuz to whatever the latest kernel installed is, same for 
the initrd.

But Fedora doesn't, which will be the case if I ever get it booted and let 
the update run, and then of course it won't be able to find the old, been 
removed kernel.  Mint8's grub 2 screen looks cool FWTW.

Slash would appear to be there, but I haven't wandered around and found where 
I put /home yet, shoulda wrote it down I guess, and I'd like to make /root a 
separate partition too, I have it separate here on F10 after I copied the F10 
from a failing drive to a fresh 1Tb drive, which sped this box up by about 
4x, so I may just re-install again.  But that is only a 370GB drive.  With 
the monitor problem being foremost, it will be a day or so before I get back 
to this.  I have another Samsung digital tv I can use for a monitor and have 
for troubleshooting another box, its tuner failed but its awfully close to be 
too darned big for the space it has to fit into.  Tape measure time I guess.
