Installing 2.21 on a fast Pentium III

I was wondering if anyone has had luck installing QNX 2.21 on a
Pentium III 700 mhz+. I can’t get the install disk to boot on this
machine. There is no way to lower the processor clock speed.

I have downloaded the speed patch utility, and it does allow my to
boot the disk on a 200 Mhz machine, but not the 700. Any other tips
that might allow the install floppy to boot? Thanks for any
information

I would bet against that being successful, sorry.

You MIGHT be able to do something like move the hard-drive to a
machine that will boot, install on it, then move it back to the
fast machine. Maybe. If the BIOSes both take the same view of
the hard drive. Maybe. Can’t think of anything better to
suggest, sorry.

hello
I’ve heard from a qnx2 specialist here in Germany, that qnx 2 works only
with processors up to 133Mhz
wtih 166 Mhz there should be driver or something.
If you need more information I can contact him.

“works” depends. I have QNX2 working on a 200Mhz P1, and a
350Mhz PII. To get the floppy working I sometimes have to
slow the cpu down by disabling their cache’s. I don’t
know what the absolute limit it.

it really depends on the machine…

i have run qnx2 on a 550 PII, but i was unable to use the floppy.
you will need to use the speed_* utilities available in
/usr/free2/qnx2.21/qnx_utils

Hi,

I’ve got QNX 2 running OK on an AMD Duron 800. I Used the speed patch
utility to rework the boot image on the floppy and I still have to disable
the cacheing in the BIOS if I want to use the floppy (which I rarely do…).
Other than the floppy problem, it works v.well!!
