It's a 600SC - P4 1.8 - Perc3/SC

Since new, I've added a Plextor CD-RW (IDE), Lite-On
DVD-ROM (IDE), and an ATI All-In-Wonder VE (7500,

I tried this as well.  Unfortunately, removing the
EISA device did nothing to relieve the problem with
the NMI.  The only thing that cleared it up was adding
'hw.pci.enable_io_modes=0' in /boot/device.hints.

This was the case, at least, with 5.0-RELEASE.  I've
yet to see what happens with -CURRENT.  Perhaps I'll
try and cvsup -CURRENT, remove
'hw.pci.enable_io_modes=0', and see what happens.

I pulled these two drives from a WinXP machine, and
based on the transfer method reported in XP, it was
using DMA.  No stability issues were noted, at least
in regard to XP.  I've been running them under 5.0 now
for a few days, burned a few CD's and played a few
DVD's without stability issues either -- thankfully.

I'll check out the above referenced manual page and
make the suggested changes.  Thank you for the tip.

Unfortunately, no.  I've even contacted Dell regarding
this as I could find no information in the
documentation provided with the system.  They simply
stated that when another video card is installed, the
integrated video is disabled.  They also mentioned
that this type of configuration "is not supported." 
I've looked for jumpers on the motherboard itself and
only found jumpers for clearing the BIOS password...
nothing else.
Thank you once again, Scott, for your help.  It was
very much appreciated.
