SCSI cards for SMP?

I am writing this on my WinXP machine, as my new dual-core Athlon eCS 
1.25 machine is in pieces at present while I try to decide whether I 
want to downgrade it from SCSI to IDE just to get SMP working.

Others have reported that a dual-core Athlon in an Asus A8N-E 
motherboard works fine on eCS SMP (using the ACPI package from the 
BetaZone) -- except for the on-board networking.

I disabled or removed everything on mine except the LSILogic-based 
Tekram U160 SCSI card, and still it will not work in SMP mode: it hangs 
on the driver for that card.

Before I capitulate and install an IDE drive instead (I have one that I 
bought for something else but haven't yet used) and discard the new 
Ultra 320 drive I bought just a few weeks ago, can anyone suggest a SCSI 
card that is known to work with OS/2 / eCS SMP? Somebody reported 
earlier that he has SMP working on an IntelliStation with on-board 
Adaptec SCSI, but I came across an old message by Scott Garfinkle that 
Adaptec cards are picky about motherboards (but that pickiness has 
presumably been taken care of in an IntelliStation).

What about the more recent LSILogic cards, the ones that use the LSIMPT.ADD?

Or is anybody using a card that uses the SYM_HI.ADD driver on an SMP 
machine? In that case it may simply be a matter of trying to force it to 
use something other than IRQ11 -- or everything else that wants to use 
IRQ11.

I have eCS 1.25 SMP working well on a Dell 410 dual 600 PIII 
using a ServeRAID 3L and the last OS/2 ipsraid.add (v7.00) driver
from IBM. I have Warp Server running on a Dell 420 dual PIII 933 
and working fine with a Tekram DC390U2W card - driver is the last
one from Tekram:

20.04.01  14.05      26002          33  TMSCSIW.ADD

HTH.

I removed the SCSI controller, installed a spare IDE drive, and 
installed eCS 2.0 Beta 2, and enabled SMP. Everything seems very fast -- 
except anything disk intensive. And for some strange reason Firefox 
won't let me download/save files: the "OK" button is grayed out.

i did try attaching the SCSI drive chain, via a 68/50 adapter, to a 
2940. It booted as far as the pre-Desktop blank blue screen, at which 
point it hung with an immovable clock pointer. I know the performance 
would have been terrible, but I just wanted to see if it worked at all.

I have purchased an Adaptec 29160 (on eBay), which Jim Read reports 
up-thread is working for him.

Add:
SET NSPR_OS2_NO_HIRES_TIMER=1

to config.sys - some versions of acpi cause problems with the hires 
timer...

I have been playing with the system for a few days now with the Adaptec 
SCSI card installed, but without success.

This SCSI card is assigned IRQ11, INT#A (just as the previous one was), 
which it shares with the ATI X300 video card and one of the on-board 
devices (USB controller, IIRC). Installing the card in a different PCI 
slot (there are only three) makes no difference.

All is fine until I replace the W4 kernel and loader by the SMP ones and 
use the /SMP parameter on the ACPI.PSD line in CONFIG.SYS. Once I do 
that, the machine crashes with a Trap 000d just as it is about to 
display the desktop.

I tried installing eCS 2.0 Beta 2 in a separate partition, but this does 
no better. In fact merely replacing the W4 kernel and loader with the 
SMP version but including the /UNI parameter on the ACPI.PSD line in 
CONFIG.SYS does not enable the machine to boot: this time I get a Trap 
0008 just as it is about to display the desktop -- even after disabling 
SMAP and reverting to the GENGRADD video drivers. With the /SMP 
parameter it gives the Trap 000d, just as for eCS 1.2R.

Others have reported that all these individual cards and drivers work 
with eCS SMP, so it must be the interaction between them and the 
motherboard that is the problem. Drivers that play nice with the nForce4 
chipset seem to be a little way away.

Now I have to decide whether I want to slum it with a slow IDE drive (at 
least it's a Seagate, so it has the same 5-yr warranty as my SCSI 
drives) or slum it by using only one of the CPU functions for which I 
paid (and a single-core CPU costing the same would likely be faster).
