Re: [PCI] 8500 no-start_update + chain terminations

[Daniel Dickinson]

The ID doesn't matter for termination (it may matter for other reasons 
but they have nothing to do with termination).  (Simplified) The device 
at either end of the the cable must be terminated.  Normally this means 
the Mac (which is already terminated), and whatever device (hard drive, 
cd, etc) is at the far end of the cable (or on the last port of the 
cable put in a terminator and don't terminate the devices).

As to what jumpers to use/not use.  That gets whacked because different 
companies do different things.  Basically you need to make sure that 
termination isn't active, and that only the terminating devices are 
supplying termination power (too much term power is bad).  Thing is, 
some devices won't do term power if term enable is off, but others have 
them as independant settings (yes, really).  Best bet is to find pdf 
manuals for all the devices and read.  It's a pain, but the only sure bet.

Cheers,
Daniel
