Making a new SCSI bootable CD from a burned qnxrtp.iso

Hello,

to spend the time until a new and SCSI bootable qnxrtp.iso appears: Is it
possible to make a new
CD from the current qnxrtp.iso burn? As far as I see the boot image is an El
Torito one. That means one must have a floppy with the boot image and has it
to burn. After that one could copy all files from the original CD to the
new. If I could make a boot image floppy containing only the specific SCSI
drivers I need the space on a floppy disk may be sufficient enough. The
question is, which files are needed on that boot image. Are there some
guidelines available?

Regards,
Roland
