QNX installation Problems

Hi.
If just downloaded the QNX RTP ISO.
Everything fine so far, I can install via Windows into an image and I
can create the bootdisk and install this way. But thats it.
Everytime I start QNX it hangs up.
Windows image: “Can’t find packages”
Via Botdisk to Partition: Nothing at all, only “Press ESC for
…alternate?01”

What I did, what I have.
Windows Image:
Installed on the primary partition of the first harddisk (FAT32)

Partition:
Installed on a 2nd primary partition on the second harddisk. (below 8.4
GB)
Booting via Powerquest Bootmagic, as the QNX internal bootmanager (which
is said to be installed) seems not to work.
Other systems installed are Windows98 and Windows2000
Partition map: HDD 1 - One partition FAT32
HDD 2 - 1st: NTFS, 2nd QNX, 3rd extended with one partition FAT32

System:
ABIT Bp6, 2 Celeron 500
2 HDDs on normal IDE
1 CDROM on normal IDE 1 on UDMA66
ATI Mach64 CT (primary) & Voodoo 3

Any suggestions?
Thx
Arne
