QNX6.21 dual boot

It, was some time ago that I used QNX, at that time I had problems with dualbooting linux, how is it working with qnx6?

It would be great to be able t ouse QNX again.

There have never been any issues dual booting QNX. Either tell the QNX install to leave the MBR bootloader (Grub/Lilo) alone or use the QNX MBR bootloader and put Lilo into the partition boot block under Linux. If you use Lilo/Grub in the MBR, simply add in a section that is just like booting Windows. ie:

other=/dev/hda3
label=QNX

I guess I f**ked someting up last time
