Is there a time limit when to change from boot disk to backup ?

[dust2dust]

hmm
i disagree charlie
all thats done u loaded memory 16(my case fmextreme)
chip still has to enable u boot backup
hmm put a diff way
if u had no chip
u could still get this far
memory or fmxtreme would still boot
still give u option to put your game in
but it would boot as i think this were chip starts
before this it just reads loads my fmxtreme disk
