QNX ISO won't boot on Tekram DC-390U

Hi,


I have decided to give QNX RTP 6.1.0 a try, so I downloaded the iso, checked
that the
MD5 checksum was correct, and burned the image using Nero (latest version).
Nero detected
that the ISO was bootable, by the way.

I have a slightly peculiar setup when it comes to storage.
I have a SCSI Tekram DC-390U card (ncr5c875 chip) on which are 2 hard disks
(2 gigs and 1 gig) and a Yamaha CD-Rom. I also have a 2 gigs seagate EIDE
hard disk
as masteron the secondary controller of the motherboard.

The ISO won’t boot in the CD-Rom (“Operating System Not Found” BIOS message
because
the disks were frormatted for the install). I have read in the SCSI
controller manual that it will
only boot devices which have 512 bytes/sector as a block size. Could it be
that the ISO is burned
differently, or does it have no bearing? I’m pretty sure the ISO integrity
was good when I burned it,
and I selected a low speed (4X) to ensure a flawless image.

Is there a solution to this? Can I use a floppy for the kernel/root loading,
and then switch to the
CD for package installation (I haven’t seen the option anywhere)?

Also, I tested the iso in my windows machine, and it works (gonna test if it
boots soon). I made the
boot floppy in hopes that it would do the job but it crashes in an odd way.
When I don’t disable “detect
other storage devices besides EIDE” (or close, I don’t rememeber the exact
term), it crashes right
after detecting my SCSI card by repeatedly writing “Too Much Data SCRATCHA0
0 SFBR 0 IntType 11”…
And it won’t allow me to continue the install anyways when it doesn’t
crash…

That’s it! If you can make something out of this, please help! Thanks in
advance,

I just checked with another computer and the CD boots perfectly (it’s very
impressive, by the way).

The Demo floppy boots as well on the faulty computer, but I don’t think it
bothers detecting the SCSI adapter… It’s definitely something wrong with
the tekram, I guess. It’s strange because no other OS ever gave me problems
with it.

Ok, so I fixed the first problem, it was simply the SCSI card’s BIOS being
buggy. I upgraded it to the latest version and it now boots the CD
flawlessly :slight_smile:.

The second problem however, is still there, and I still haven’t found a
place even mentioning it!
When I start the install, it crashes immediately after detecting my
ncrc53875 SCSI card and the SCSI chain (i.e., enumerating the SCSI devices).
The crash symptoms consist in displaying a message “Too much data SCRATCHA0
0 SFBR 0 IntType 11” repeatedly. The keyboard does not answer either.

When I disable the enumeration of any other controllers besides EIDE it does
not crash, simply complains that it “could not find finstall” (which is on
the SCSI CDROM). Also, the QNX 1.44 demo disk (network version) works, but
then again it doesn’t poke the hard drives.

Here’s my configuration:

  • P2-266, generic motherboard,
  • 1 seagate on the second EIDE on-board controller (the first controller is
    disabled), 2 Gigs
  • Tekram DC-390U SCSI controller (ncr53c875 chip), ID-7
  • 1 Seagate SCSI hard disk, internal, ID-0, 2 Gigs
  • 1 Yamaha CDRW 4260t SCSI CD-ROM, external, ID-1
  • 1 Seagate SCSI hard disk, internal, ID-3, 1 Gig
  • RealTek 8129 network card
  • No Sound (well besides the speaker :slight_smile:
  • 1 floppy drive.

Can anyone make some sense out of it please? I guess this is more of a
technical question that a developper could solve, which is why I give
details about my hardware setup.

Thanks in advance!

Ok, just another update to say that I have tried starting the install from
an EIDE
CD-Rom on the same computer (just removed the SCSI cdrom and replaced with
another one in EIDE) and I still get the crash after the ncr8 detection
message…
