[ I *hate* trying to read and answer questions that get word wrapped
into unreadability, don't you!  Of course that's how my AGP question
came out, so let me try it again. ]

I have a perplexing problem getting a new Diamond Viper 550 AGP (16MB)
to be recognized and come up under NT 4.0 with Service Pack 4 installed.
This is on a Micron Millennia XI desktop with 400MHz Pentium II, 128MB
of RAM, Phoenix BIOS 4.0 release 6.0.  The AGP itself has BIOS level
1.94C.

The symptom is that after following all the instructions, removing all
previous drivers, booting it to VGA, changing the display type (either
via running X:\START.EXE from the driver CD or via "Have Disk..." from
the display applet), all software apparently installing OK, and
rebooting, it STILL comes up in 16 color VGA mode and the "Invalid
Display Settings" popup appears.  Nothing I can change or set or do
changes this.  NT Diagnostics shows the driver installed, but VGA Save
is the active video.  I reinstalled the Service Pack and everything else
I could think of, to no avail.

The BIOS on the Millennia is set up with Plug+play OFF.  I am told in
some postings that I should reserve an IRQ for the graphics card, but
supposedly it likes IRQ15 by itself and the BIOS SETUP interface doesn't
offer 15
in the list of IRQ's to reserve under "Peripheral Configuration." 

This machine has Windows 98 on another partition, and the AGP came up
immediately for Win98 and works like a charm in all modes (except I
don't get textures in the Descent 3 Demo, but that could just be the
demo).  Under
98 it takes IRQ 10.  Under NT that IRQ goes to the on-board Crystal
audio.

Has anyone seen any of this and does anyone have any suggestions?  I'm
about ready to start pounding my forehead, which usually hurts me more
than the problem. :)

Happy holidays!
