In Reply to: RE: IMPORTANT note for nLite users.. posted by Jolida on December 02, 2011 at 02:23:41
so I need to try leaving that in.
I will say that the LUCY tool gave me the same basic latency as I had got before. I do not know how to do the measurement you are speaking of. Missed something (AGAIN).
That must explain why I do not have the acpi.sys in my installation!

There is a lot of difference in sonics if Multi-Processor is not selected. The Pc should be installed as Acpi Multiprocessor Pc. I just finished a new nLite install, & it sounds great out of the box. I'm sure there is a much larger scope for improvement with this one...
Rick, U had not selected Multiple processor support. Please make a note of it. It's very very important ..

I think you might want to try installing with optimized BIOS and see if it makes the same difference.
If the MB only sees one core what's the point of multi processor support?
When cics was recommending the hardware set he said that it is enough to enable only one core, it will do all the multithreading (2 simulaneous threads).

I installed as an ACPI multiprocessor, then reverted bios to
CORES ENABLED 1
Serge.
P.S. there is more to acpi-multiprocessor, but let me finish the cmp. Stuck with awe.
Even if u do an automatic install, it will sense the Pc as a multiprocessor.
Though only one core is enabled. U can check with Ur previous back-ups as well, & all will show the installation as an Acpi Multiprocessor Pc.
That's exactly why I was insisting Rick to retain Multiple Processor support. Else u will only have a standard install which sounds a lot different that this one..

One has a choice of ACPI Uniprocessor or the i486 C-Step that I chose since it has long been said that many times the older technology was better for our purposes.
And with the benefit of lower power requirements.
I can assure you the install is anything but bland. I am hearing much greater dynamics on drums and a surprising increase in low bass energy. Energy I had been missing.
I will try the other way but even then I will still install with only one core working and choose ACPI Uniprocessot.
As u please my friend :)
As far as u like it. That's what counts..!!

I so knew that question would come up :)
I can answer that in one line. If the OS is seeing only ONE core in the bios, then HOW DOES IT INSTALL AS AN ACPI MULTIPROCESSOR PC, when the setting are in Automatic?????
As simple as that. Even I have disabled multithreading in my Bios long back, & only one core is enabled. But inspite of that, windows recognises it as a multiprocessor. I guess there is something more to it that just enabling or disabling...
The nLite disc which I have uploaded was made with Multiple processor support enabled and the Computer type I left it to Automatic.
Try installing with that disc & I'm quite sure that even ur's would be installed as an Acpi Multiprocessor, even though only One core is enabled...

I have no idea where to look.
I am sure it is in the registry somewhere.
I do know that acpi.sys was not installed.
I will give it a try but I am mystified why the installation would override the BIOS when it doesn't for other things.
Try
http://falconfour.wordpress.com/2011/03/19/how-to-switch-windows-xp-hal-_back_-from-standard-pc-to-acpi-the-clean-way/
Where to look, it should be
HKLM\System\CurrentControlSet\Enum\Root\PCI_HAL\000
When you have non-ACPI, it should state 'e_isa_up'. Eventually you are lucky that way, but the site says, that afterwards you have to update the (fundamental) driver of it using MMC/ device manager.
Probably this is some regvalue too.. If you have the time, consider a re-install using ACPI from the start, I think honestly this would be a more clean approach as to not break things :)
Just go to Device Manager & open the first tree names " Computer". There u can see the type of installation been done.
Cross-check this in Ur nLite install with the previous images u had backed up, by restoring any non-nLite image u had earlier. I'm sure all Ur previous back-ups will have used the Acpi Multiprocessor Pc...

Standard PC with C-Step i486.
Something to consider:
When I installed nLite my BIOS is set for the use of only one of the cores of the CPU.
As with the 1394 and the other unneeded ports left disabled at install so they don't install or at least are minimized, I wonder if the same thing occurs with this MULTI PROCESSOR thing?
If the installation only sees one core ...
I have not noticed any abberations in the sound that would point to latency problems and as I said LUCY would give me the same basic latency which my memory thinks was 32 as it was in every other install nLite or otherwise.
Could it be important to have this BIOS setting at installation?
