Interesting boot problem

Ill start off with a hardware partition info run down 2 10 gig seagates,
primary and master and slave a mitsumi ide cd burner and a hitachi just
player. The latest qnxrtp will boot fine if the slave is disconnected or if
a smaller hdd is in the slave but as soon as i plug my drive back in it gets
to the “this will take 30 seconds” bit and thats as far as it goes.

the partitions are as such hdd1 is fat qnx fat fat fat unallocated
hdd2 is fat fat (fifty fifty)

qnx is in a parition of its own which is 900 to a gig in size and it falls
well with in the 8 gig limit which this BIOS doesnt have anyway.

Any ideas ??
