Mounting QNX drive in RTP

I have a eide drive with two ~4Gb partitions type 77 and 78 (QNX4). When I
boot RTP, /dev shows /hd0, /hd0t79, but only /hd1. NO ‘special block files’
hd1t77 and hd1t78. Therefore I can’t mount these partitions. Any
suggestions?

I had exactly that problem. Make sure proper geometry is passed to the
driver serving hd1. Use ‘disk translation=…’ to pass it.

How? Where? When? Excuse my ignorance I am familiar with QNX4 and Windoze -
not RTP or Linux.

If hd1 is served by the same driver which serves your bootable drive,
you have to pass option for driver using diskboot’s -o option in the
boot image, then rebuild image and reboot. Otherwise the driver can be
simply killed and restarted with desireed options at any time.

See docs for cam-disk, diskboot, mkifs. If your drive is EIDE then
perhaps you should pass geometry using ‘eide geometry’ option instead of
‘disk translation’. I’m sure Kevin or docs people will gladly clarify
this ambiguoty. See devb-eide docs then :slight_smile:
