- NoIDE version 1.0 by Matthew Frost (11th September 1994)
- =========================================================
-
- A HACK to Disable the IDE device on an OS3.1 equipped
- Amiga A4000 preventing a 25 second boot delay when no
- drive is present on the system.
-

-
- Background:
- ===========
-
- I used to have a problem on my Amiga 4000/030 that
- my IDE harddrive was slow to spin up and used to
- (occasionally) take longer than the 9 seconds that
- Commodore allowed for in the 3.0 ROMs which meant
- that I got a boot screen on every COLD reboot.
- Now that I have got an A4091 card and a SCSI-II drive
- I have removed my old IDE drive and that gave
- me a 9 second delay before the system would even touch
- the SCSI drive. Not too inconvenient though.
- However, having upgraded again to 3.1 ROMS I found that
- Commodore had changed the timeouts to at least 25 if
- not 30 seconds and this REALLY got on my nerves. A 25
- second wait EVERY time I rebooted the machine!
- I thought there must be some way to prevent the IDE
- device from being checked. So I came up with this hack
- - and it IS a hack - problem solved for the moment.
- Why Commodore didn't put a battmem option to disable the
- interface on the system is beyond me - Even a jumper on
- the motherboard would have been nice. Anyone know how
- to do it in hardware by an adapter on the IDE cable??
-
-
- Requirements:
- =============
-
- Amiga A4000 and Kickstart 3.1
-
-
- Installation and Usage:
- =======================
-
- 1) Copy NoIDE to your C: directory.
- 2) Insert a line in your startup sequence like so:
-
- Run <>NIL: C:NoIDE
-
- (I put mine straight after C:SetPatch)
-
- 3) Reboot the machine and you'll get the delay still, but
- the next time you do so it should be MUCH quicker.
-
-
- Caveat:
- =======
-
- Only works on Kickstart 3.1 for the moment (as soon as I
- get access to an OS3.0 A4000 again I can produce an OS3.0
- version for those that want it - Email me if you require it).
