Booting a Minimal QNX6.5 from a HardDrive   
The project that I'm working on requires a minimal QNX 6.5 system witch runs on an x86 platform.  Currently the .ifs 
image we are using can be booted from a Thumb drive and works great.  I now have to move this image to a Hard Drive. 

 I can fdisk and mount the drive and I can copy files to it, but when I make the hard drive the main boot device it won"
t boot.

I not sure what boot loader I'm suppose to be using and I'm also not sure if the drive is formated correctly.  I'm sure 
someone has done this before, and I'm looking for some direction.

Regards,
Mark

Re: Booting a Minimal QNX6.5 from a HardDrive   
Is there an error message when it fails to boot?

Re: Booting a Minimal QNX6.5 from a HardDrive   
Thank for the response.

No there is no message of any kind.

My first problem is I think that I'm not get the disk formatted correctly because the partition table look very strange.

Re: Booting a Minimal QNX6.5 from a HardDrive   
It appears you did...

dinit -h /dev/hd0
or
mkqnx6fs /dev/hd0

These would destroy the partition table as your post indicates.

Use fdisk first and create the type of partition you want ... 77 or 177 (qnx6fs)
Then specify the partition device, i.e. /dev/hd0t177 rather than /dev/hd0.

Re: Booting a Minimal QNX6.5 from a HardDrive   
what is the difference between these two commands;
fdisk /dev/hd1 show
and 
fdisk /dev/hd1t177

I get two very different results, which one is correct?

RE: Booting a Minimal QNX6.5 from a HardDrive   
"show" just prints the disk partition table...without it you can manipulate it.
/dev/hd1 is the raw partition, whereas /dev/hd1t77 is the QNX6 partition(don't do anything with this one)

What does the output of "fdisk /dev/hd1 show" say?

RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
So this is good, you have a bootable partition on your disk...ignore the fdisk /dev/hd1t77 wrt. fdisk.

So now you need to run "mkqnx6fs /dev/hd1t77" to create the qnx6 filesystem on your partition.
Then reboot/restart the io-blk driver, and put your disk partition should show up as /fs/hd1-qnx6 and put your ifs file 
in /fs/hd1-qnx6/.boot/
Then power off and remove your /dev/hd0 disk, upon reboot the loader should show you the ifs that is in your /.boot/

Re: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
Almost there.  After performing the above, and rebooting I get a meessage on the screen "QNX v1.2b Boot Loader" and a 
blinking cursor.  I think the issue is not being able to copy my ifs from one drive to another.  This is basic but I'm 
have trouble.  I believe the command should be 
    cp myqnx.ifs /fs/hd1-qnx6/.boot and the ifs goes from hd0 to hd1.

regards,
Mark

RE: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
/fs/hd1-qnx6/.boot/ is a directory, which is where you need to put you're ifs.  You may have written over your /fs/hd1-
qnx6/.boot/ directory with your cp command ;-)  If so, you would have to rerun the mkqnx6fs command to recreate the qnx6
 filesystem.

When you remove the hd0 drive then reboot; the loader(on the secondary disk which is now the primary) should show your 
ifs as a selection to boot from.
Once booted, as long as you have the io-blk driver(and required libs) running in your ifs, then the hard-drive should 
show up as
/dev/hd0 and hopefully be mounted as /

Now this filesystem will be empty unless you've copied files over to the /fs/hd1-qnx6/ previous to removing the initial 
disk.
If you get as far as selecting you're image and it doesn't boot properly, post your myqnx.build file.

Re: RE: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
Chris,

I'm so close.  I re-did the "mkqnx6fs /dev/hd1t177" command just in case screwed up something.  I then moved a copy of 
my bootable ifs image that's on hd0 to the /fs/hd1-qnx6/.boot directory.  I know that this is a working image.  I remove
 hd0 and make hd1 my new hd0 and boot.  I get the qnx "v1.2b Boot loader:" message but that's it.  What I have noticed 
is that there is a previous message that I get with the working hd0 "Press F1-F4 to select drive or select Partition:", 
I don't get this message with my hd.

Also another bit of information. If I have both drives in the system and when it boots I can select drive 2 and it will 
boot from drive 2. So it seems to me that I'm still missing something in the preperation of my drive. Something is still
 missing.

Regards,
Mark

RE: RE: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
I'm not sure at this point, but I would think that the boot loader would have been written with the "mkqnx6fs /dev/
hd1t177" command...but try rewriting the boot loader with:

"mkqnx6fs -B /dev/hd1t177"

If this doesn't work, then I'll get one of the file system guys to jump in.

Re: RE: RE: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
Chris,

I tried the mkqnxfs -B /dev/hd1T177 command and still no fire.  If there is someone else that you think might be able to
 help that would be great.  I really appreciate your help, you've been great.

Have a good weekend.

Hi Chris,

Success,  thought you would like to know.  The final piece of the puzzle was "dloader".  I didn't realize that two 
loaders were required.  It now makes sense.  I found a piece of documentation over the weekend that solved the problem. 
 

Thank you ever so much for all of your help.

Best Regards,

Mark

Can you send me a link to the documentation you found?

Re: RE: RE: RE: RE: Booting a Minimal QNX6.5 from a HardDrive   
The only reason I found this was as a result of a search for the string "Press F1-F4 to select drive or select partition
 1,2,3? 1".  This link kind of outlines everything.

http://www.qnx.com/developers/docs/6.3.2/neutrino/user_guide/starting.html

Again, thanks for the help.

Mark
