QNX RTP not booting with Grub

Hello!

I have QNX installed on my third physical drive (hd2). When I try booting
it using grub, I get the following:

press esc for alt os…?04

It just sits there at the ‘?04’ not doing anything.

Here is what the boot looks like in Grub:

root (hd2,3)
chainloader +1
boot

I have also tried it with a map 0x80 0x81 and a map 0x81 0x80 command in
there along with makeactive. If I use those, I get a ‘?01’ instead of a
‘?04.’

Any help would be much appreciated.
