OK. Well, that's a bit different, then. If the image could not be read you'd
likely see a 'C' at the end of the dots. 

Jeevan had a suggestion to try it with a pre-installed drive. If you could
try that then at least we can see if it's a generic problem (i.e.  bad
instruction causing a fault or reboot) or a problem specific to the CD
image. 

If the issue is specific to the CD: What options do you have on that machine
for booting? Do you have a floppy? What about USB devices? There are options
to startup and procnto or increasing the verbosity but, of course, you need
to make a new boot image and somehow boot it. USB drives or floppy are the
easiest in this case. 

Cheers,
Keith

This is what I am able to see on the screen:

--begin--

Hit ESC for .altboot....................................................

--end--

and then it bombs.

In short, I am not able to see the line:

"Press space for options"

Hi Kushal,

Ahh...you see the dots? That's a good sign, anyway. What, exactly, is on
the screen before it boots? How far along the following sequence does it
get:


--begin--

Hit ESC for .altboot....................................................
...........................

Press space for options

--end--

That would help me to diagnose the problem...

Hi Keith,

Thanks for your response and instructions.

I have verified checksum and it is correct. Also just to test out, I
tried booting the CD on a different configuration board and I was able
to boot and install QNX. But when I try to boot on my original board
(VIA) it just bombs.

I think the loader is able to partially load itself because I do the
initial message: "Hit ESC for .altboot"

And then the CD makes sound as if the loader is going to start its
operation and I can see the progress bar of dots (.....) moving forward
but then it just bombs in 3-4 seconds and the system restarts.

What else can I try to debug this issue and find out what is happening
behind the scenes?

Thank you once again.

Kushal

Hi Kushal,

The first things to do is to verify the CD was burned correctly. And
that the downloaded ISO was not corrupted. You should verify the
checksum of the downloaded ISO against the values posted on the download
site. 

The boot image isn't being loaded. This means the OS hasn't been loaded
so any question of disk drivers is irrelevant. The boot loader uses BIOS
calls to load disk sectors directly into RAM so either the ISO (or CD)
is corrupt or something very, very odd is happening with the boot
loader. It's remotely possible that the loader is using BIOS
instructions which your BIOS doesn't handle (i.e. newer instructions on
an older BIOS).

If the checksums verify then there are a couple of other things to look
at. If there is a floppy drive you can try making a custom boot image
using a different loader. That's a stretch, though. 

Cheers,
Keith

Contact Your QNX- sales/support rep to get one.
Or search the web for something like ipl-diskpc2* ,*= quite , nomsg, fast etc...
(A few years I go I found one or 2 but that link is broken now.)


Then use dloader utility to get it onto Your hd drive.

Docs You should read:

/root# cd /boot/build

edit for example this file:

/boot/build# ped qnxbasedma.build
#
# The build file for QNX Neutrino booting on a PC
#
[virtual=x86,bios +compress] boot = {
        # Reserve 64k of video memory to handle multiple video cards
        startup-bios -s64k -vvvv #Here the vvvvvv's

        # PATH is the *safe* path for executables (confstr(_CS_PATH...))
        # LD_LIBRARY_PATH is the *safe* path for libraries (confstr(_CS_LIBPATH))
        #    i.e. This is the path searched for libs in setuid/setgid executables.
/boot/build#

mkifs -v qnxbasedma.build /.boot //build the image 

reboot the machine.
