Now the system informs, that frequency of the processor 420 MHz.

Hi Gennadiy,
Can You please try to be more detailed regarding Your hw ?
show_pci -vvv
sin
sin in
sin ver
BIOS version and a web link to the specs would be good.
Anyhow, what comes in my mind is:
Did you tried to disable hyperthr , PNP OS, usb-Emulation in Your BIOS, if possible ?
Donno but, that sin info reports 420MHz wrongly could be a pure sin problem .
Are you using QNX425 Patch G ?
Hope this helps.
Regards,
Jeevan

The Proc425Q release notes
http://www.qnx.com/developers/articles/rel_1482_1.html#FIXTHIS
say :
[snip]
modified information returned to sin info, so that the cosmetic benchmark speed reported maxes out, rather than wrapping
and showing a 'slow' speed

Incorrect the information on frequency gives Proc32 at loading OS. Manipulations from a BIOS have not given effect.

Please try attached /boot/sys/boot.

Re: What adjustments BIOS, Proc32 and etc, for effective work QNX 4.25 on the processor with Intel Hyper-Threading Technology should be?
QNX4 can experience problems when running on faster CPUs as a result of CPU speed being calculated incorrectly. If "sin
in" reports an incorrect value your system may be affected and I recommend that you apply "/boot/sys/boot for QNX® 4.
25 Patch (Patch ID 515)" - it is not on our Download site, so ask your sales or support representative.
Details:
CPU speed is calculated by "boot" utility at startup - "boot" is usually a first line in boot image. On faster CPUs (~1.
8GHz and higher) CPU speed may be calculated incorrectly. Some drivers (not all) use this value to calculate timeouts
and will experience problems, e.g. Fsys.atapi very slow to start-up.
This problem is not directly related to Hyper-Threading.

Thank You Alexander.
The boot.zip what I attached ito my last post is exactly Patch 515.
So Gennadiy can just go ahead ,copy it to /boot/sys/ rebuild his bootimage and should be fine.
And no worries, I got approval for posting it there.
Regards,
Jeevan

Re: Qnx 4.23 on a Pentium 4 system?
I using QNX4.23A. I did a fresh install on a brand new system, Pentium 4 2.8Ghz, 1 GB RAM, 40GB hard drive (ah, the joy
of a 12 year old floppy disk). The QNX4 partition is 8GB with the rest of the hard drive unformatted.
The program I'm using forks multiple processes and requires a total of 12MB. 'sin info' informs me that i have only 8.
5Mb free out of 16.3Mb (total memory) which are obviously incorrect numbers, the processor speed number in 'sin info' is
also half that of a P3 550Mhz machine. Needless to say the program i'm running spits out a EAGAIN error when it tries
to create all the processes.
I changed the build file to set a max of 1000 processes (from the default of 500) and checked 'fsysinfo' which showed
plenty of free heap memory, inodes, files etc. So I'm sure that's not the issue. Just to see if there was any other
crazy software issue, i plugged the hard drive into a Pentium 3 system with 256Mb RAM and the software worked fine.
Will the build file posted in this thread work on Qnx 4.23A? Is there any other way to make Qnx 4.23A recognize the
correct processor speed and RAM? Any other thoughts/suggestions will be appreciated.
-DB

Re: Qnx 4.23 on a Pentium 4 system?
The problem was fixed with Qnx 4.25 Patch posted in this thread. The processor speed still shows up incorrect during the
boot script but the system RAM is now recognized correctly. 'sin info' shows the full "correct" system memory available
.
