I've already tryed BusID - the same as ever.
In README.Linux I found next interesting things:
(1)
HARDWARE ISSUES
This section describes problems that will not be fixed. Usually, the
source of the problem is beyond the control of NVIDIA. Following is
the list of problems:
.......
o VIA KX133 and 694X Chip sets with AGP 2x
On Athlon motherboards with the VIA KX133 or 694X chip set, such
as the ASUS K7V motherboard, NVIDIA drivers default to AGP 2x mode
to work around insufficient drive strength on one of the signals.
........
But I used my card (on motherboard Acorp 694XA with VIA chipset) on
Windows with AGP 4x normally.

APPENDIX H: TNT SPECIFIC ISSUES
Most issues pertaining to SGRAM/SDRAM TNT cards should be resolved.
There is the rare chance, however, that your video card has the wrong
BIOS installed, and that this driver will continue to fail for you.
If this driver fails for you, do the following:
o watch your monitor as the system boots. The very first, brief screen
will identify the type of video memory your card has. This will be
either SGRAM or SDRAM.
o edit the file "os-registry.c" from the kernel module sources. Look
for the variable "NVreg_VideoMemoryTypeOverride". Set the value of
the variable to the type of memory you have (numerically, see the
line just above it).
o since we don't normally use this variable, change the "#if 0" that is
about 10 lines above the variable to "#if 1".
o rebuild and reinstall the new driver ("make")
About rare chance - I used this card on RH Linux with this sort of drivers
and it worked.
What they mean by this rare chance? Who that people that install the wrong
BIOS? And who is responsible for it? It can be treated by me like a
product malfunction...
At first when computer reboots I see only 16.0M RAM without any mention of
SDRAM or SGRAM. At second I have no os-registry.c on my computer (probably
it should be only in linux distro of drivers). I issued grep and found
that variable is in nvidia_os_registry.c. I opened it and saw that there
is no #if directive at all. After some time I guesed that activation of
variables was in tail of the file and in a vary different way than
described in docs (by setting '1' in structure). Strange... I compiled
with SGRAM (value 2) and was trashed to hang up and reboot as ever. But
when I restored my machine I noticed that now the key
hw.nvidia.registry.VideoMemoryTypeOverride exist!!! I set it to SDRAM and
was punished by rebooting. Maybe I go crazy?
And could anyone receive my attachments, is it possible or I'm in trouble?
Hell... |:-)
