Two separate topics, two separate answers.

On the 10/100 angle, it depends on what's in the PROM
setting. Jumpstart will use the device that it installs
from at the speed it used. If you did a jumpstart at
10, you will get 10. If you set in the PROM to try 100
first and your networks switchs support 100, you will
get 100.

On the half/full angle, it will default to
autonegotiate if you use jumpstart. Autonegotiate will
start out hoping for full and if it starts getting
media errors it will fall back to half. The process
of packets on the line is more involved than thatbut
it does describe the end result just fine.
