How to create a QNXRTP partition from a windows installation


because I own a SCSI CDROM drive I would like to install a QNXRTP on a FAT
Partition from windows first and then after booting from floppy create a
bootable partition on an empty part of my hard disk. What do I have to do?
Which files should I take over? Is it nessecary to copy the boot sector of
the FAT partition, are bit or byte changings needed ? Has someone any
expirience in that ?
