Boot floppy sees SCSI CD-ROM but won't mount CD.

Just tried to install the latest release of QNX RTP on my Dell
Latitude XPi P75D with Advanced Port Replicator III. The APR has a
built in “ISA” Adaptec 15xx BIOS-less SCSI controller and a 3Com 509b
NIC.

The new boot floppy fails to load the PCI driver (which of course it
won’t since there is no PCI stuff in this 1995 era laptop) then it
finds the SCSI controller and loads the aha2 driver. The install
finds the CD but then says it can’t mount it as a cd.

I downloaded the new ISO file, all 256megs of it, from qnx.tucows.com
then made the CD with Nero Burning ROM using Disk At Once mode
just like I did the previous QNXRTP release.

The CD-ROM I tried to use is my SCSI Panasonic 7502W CD-R, which I
have in an external case so it can be used with my desktop PC, the
laptop and my Macintoshes.

Are there any modifications I can do to the boot disk to make it
not attempt to find the non-existant PCI bus and mount the install CD?
I tried it with and without pressing Esc when it said to, without
any visible difference, also tried normal and verbose mode.

I don’t believe aha2 is included in boot image. The enumerator might
find that it needs to be started but are you sure it actually was
started?

That site says “Installation works great…” um, the problem is
that the installation does not work because it refuses to mount
the CD after loading the driver for the SCSI controller AND finding
the CD-R/ROM drive AND seeing the CD. It says it cannot mount it as
a CD. I can browse the CD I made just fine in Windows.

I had the previous version on the laptop by hooking the drive to a
desktop and installing that way. That was just to see if QNX would
even run on the laptop, not to actually use due to the video being
limited to only 4bit. I wanted to try the latest version for its SCSI
support and generic SVGA driver to see if I could get 16bit color on
the LCD like Windows can.

Can someone make up a QNX 6 boot/install floppy image that doesn’t
look for PCI and (if that isn’t the cause) tries some other method to
mount the CD-ROM? I bet it would help many (crazy?) people like me
who want to try QNX 6 on older laptops.

Hmm, just popped the boot disk in again, says
Detected SCSI aha2 controller. Scanning for devices…
Unable to start devb-aha2 blk auto=partition,cache=32k cam quiet (No
such file or directory). Will skip.

That’s what I mean. It knows what driver it needs, but driver is not
there.
It would be easy to make a proper floppy if QSSL posted the ‘deflate’
utility for NTO somewhere.

All you need to do is start the driver, create partition table, restart
driver, dinit filesystem, mount it and ‘deflate’ qnxbase.qfs from CD to
filesystem. Plus write /.boot file of course (you’ll probably need a
custom one).

Another option is to create QNX4 based floppy since there is deflate for
QNX4 (hidden inside QNX4 based installer).

I don’t have QNX4 and don’t have QNX 6 installed on anything. I just
want it on my laptop’s old 700meg drive. :stuck_out_tongue: Can someone make a custom
boot/install disk image, possibly writaeble with RAWRITE, that doesn’t
look for PCI stuff and includes the AHA2 driver? I’m sure many people
trying to install QNX 6 on older laptops could use it!
