SMP on AMD64x2 -- no joy so far

I know others have been successful, but so far I've had no luck getting 
SMP working on my system.

I have a brand new install of 1.2 refresh on my system which comprises the 
AMD64x2 3800+ processor, Gigabyte K8N Pro-SLI 
(http://www.gigabyte-usa.com/Motherboard/Products/Products_GA-K8N%20Pro-SLI.htm)
, 
2G RAM, 74G WD SATA disk, and eVGA nVidia 6600 graphic card 
(http://www.evga.com/products/moreinfo.asp?pn=256-P2-N363-TX).

I'm using the GenMac wrapper 1.0 to provide a LAN driver for the nForce4 
NIC.  I have no sound card driver installed.  I installed the latest SNAP 
ENT driver from the BetaZone.  It does not provide acceleration, however, 
as it doesn't detect the nVidia chipset on my eVGA card.  I have a USB 
keyboard and mouse.

When I install SMP and start up, I get as far as the desktop -- it paints 
the background color and draws the cursor hourglass and freezes.  No trap 
or fault information at all.  If I rem out the OS2APIC driver it boots and 
runs on one core.  If I install ACPI 2.0 driver and enable /SMP it freezes 
just after it displays the Genmac driver splash screen during boot up.  
Again, no errors.

Any suggestions?  I'm pretty much dead in the water here, multi-processor 
wise.

Hello Joe Barnhart

ACPI.PSD:

1) please, post report to beta-zone
2) use the latest USB drivers


=========================

'''Drivers not ready for SMP (ACPI)'''

This drivers do not work in SMP computers (running with ACPI.PSD):
* AMouse -- there is a special parameter for SMP(?)
* SHOWIRQ.SYS is not compatible with APIC (6144, 04.03.00) error before 
load of PMSHELL.


'''This drivers may be improved'''
* UniAud -- doesn't work on SMP machines but may be improved;
* Scitech SNAP -- usually works but there are restrictions;

Contact the developers and make them fix the drivers.


'''Working drivers'''

* Driver e100b for Intel 10/100 network card
* System USB drivers v.10.145 or above
* RTSND.OS2, Veit's Realtek network driver, released in december 2005 or 
later -- http://kannegieser.net/veit/realtek8139.htm
* MRAID.SYS v2e.03 (MegaRAID 475 Express 500 RAID works on IRQ 18), use 
parameter /IRQ 18.
* IBMGU.OS2 network driver for Intel PRO/1000 MT Server Adapter  82545EM 
Gigabit Ethernet (Copper), for example, IRQ 21

How about a memory address problem? That's usually what trap 0d's are 
all about. I suggest you reset your bios and see if it will reassign the 

Thanks for the response.  In keeping with this being a general forum, let 
me try to get OS2APIC working.  Here is the result when I use this driver 
on my system:

I get a "trap 0d" error.

I have reloaded the VGA drivers and double-checked everything in your list 
of suggestions.  The GenMac wrapper is still an open question, but there 
is no other driver for my nForce4 NIC.  I can try to uninstall this driver 
and go back to the nullndis driver.

If anyone knows how to read a trap 0d, I'm interested in what this one 
says about my system.

That's an interesting idea.  But remember, I can boot and run eCS 
perfectly well without SMP support enabled.  Does it make sense that the 
IRQs would be toxic under SMP but not under normal operation? (Sorry if 
this is a dumb question but I'm a bit new at this OS/2 SMP stuff.)

The bios on this board does not give me many options to affect IRQs.  It 
has a setting to manually set IRQs for two PCI slots and that's about it.  
I will look at the Gigabyte site to see if there have been any updates for 
this relatively new board.
