Magneto Optical Drives

I have been using Fujitsu MO Drives with QNX 4 for years and they always
register with dev as /dev/mo (both scsi and eide). The do not show up
automagically under /dev with Rtp … so I’m looking for someone to lead me
down the golden path of enlightenment! How do I mount these drives under
Rtp???
TIA!!

Since you say that they appear as moXX under QNX4 I assume you have the
Fujitso direct access/magneto optical DIP switch set appropriately.

Is the required peripheral driver “cam-optical.so” included in your
boot image - I would be suprised if it is in there by default. You may
need to manually add it into the image filesystem and rebuild “.boot”.
You should be able to see where it belongs by searching for “cam-disk.so”.

Then, there was a bug in this mo peripheral driver (that wasn’t fixed until
late May and hence may not have been in the released RTP) that registered
the device with an “hd” prefix. Check if you appear to have any extra
“hard drives” in “/dev”; if so one will be your MO. In this case, then
until a newer cam-optical.so is released, you can specify the option
“optical name=mo” to the devb-eide (or SCSI) driver to force the naming.
Someone more familiar with RTP/diskboot may be able to advise on doing this.

My Fujitsu MO 230 MB (SCSI) is registered as /dev/hd1 automatically
under QNX_RTP 6.1.0
