Loading a graphical image can be done via the BIOS
(before the OS starts booting).

There are loaders out there (as loading is not QNX speficic).

You can look here:
ftp://ftp.qnx.com/usr/free/qnx4/os/utils/disk/

What didn’t work with that dinit cmd?

Is there asm source to modify these?
If not what utilities can you use to dissassemble them?

Attached you can find assembly code. It compiles under QNX 6.2 using nasm
assembly compiler.

Attached you can find assembly code. It compiles under QNX 6.2 using nasm
assembly compiler.

How do actually use this boot loader - do compile it and write to the first
512 bytes of the HD?

To compile under QNX 6.2 use nasm and to write to the HD use dloader.

This is a second stage loader, but it can be the first if you do not care
about partitions in your embedded system.

Example how initialize hard drive to use a second loader as a main one:

fdisk /dev/hd1 delete -a
dinit -hq /dev/hd1
dloader -H /dev/hd1 /usr/ipl-diskpc2-MynewBuildLoader

Hello guys,
I see you can help me…maybe…pls.
So my problem is that I have got installed Win2000 on first partition(17GB)
and QNX6.2 on second partition(2GB).
I want to use ntloader and in boot.ini I want add menu like “QNX”…So just
now I’m booting from floppy.
I was create the image from this floppy with name “boot.qnx” with dd utility
in QNX and I was placed this file first patition where is ntldr, also I was
placed menu to boot.ini…
Evrything look likes fine… exept if I will try this one… image with qnx
loader give me:
Press ESC for .altbootD and freeze.But booting from floppy is OK.
I know that this is reason I have got HDD 20GB and this is err message for
HDD bigger than 8GB.
And official help give me advice reinstall system with support more than
8GB.(That I don’t want).
So my question is:
Is it possible modified bootloader for QNX for my case to avoid .altbootD
error?
Thanks a lot for your comments.
Otto
