after EIDE was detected, QNX RTP can take up to 30 secs to recognize the IDE HD. In fact, on my system, it’s almost 20. That’s ok on first-time-boot, but why does it
have to detect it all again when I reboot? Why it just doesn’t take what it detected last time and goes on with it?

Because you may have added another hard drive; which you most probably want
detected.
RtP is designed as a development workstation. It should be booted
infrequently (on the order of once a month). When you do reboot the reason
is more than likely that you have added new hardware. For your embedded
targets you should typically start devb-eide manually (you can do this with
RtP if you want, but if I were you I would consider whether the 30 sec once
a month - i.e. 6 min/year - is really that big a deal - I bet it would take
close to 6 minutes to change the boot script). If you hard-code your script
and then change your hardware more than once in a year you are in the
temporal red.
btw: once/month has been my average desktop development station reboot
interval with QNX 4 over the last 13 years (9 times out of 10 to add new
hardware - .8 times out of 10 for configuration purposes - .1 times out of
10 because an interrupt handler I was working on segv’d). My average laptop
development station reboot interval is once/day since I take it with me when
I leave work (and the 30 second boot time has never really bothered me -
even booting once/day).
