Kickstart1.3
The BootPri value determines the order of the autoboot. The values
range from -129 to 127, -129 means to disable autoboot. The machine will
boot from the device with the highest BootPri, no value specified for
BootPri defaults to 0 (ZERO). If more than one device has the highest
priority, then the device furthest to the right in your machine (A2000)
will be the booted device. (BTW, RAD is defined as being the furthest to
the right at whatever priority it is set to) Look at page 3-3 in the 1.3
enhancer manual.
