Q: I have changed vars what that file is in the nvidia drivers, so it would support the sideband addressing and fast writes. I installed the new driver, and when I rebooted, SBA was busy, but fast writes just . 0.
were not when I cat / proc/nv/card0, tells me the SBA is supported and enabled, and FW are supported, but disabled.
Does someone an easy way to fix this? It does not mean very much because Im already pretty = performance in the different windows in Q3, but it would be nice to get those extra few frames / sec.
Re:No no no, don't be sorry. You've provided me with the information on WHY things don't work, and that's all I can ask. Thanks for the info man!
Re:O.K. from the info you have given me, it seems that the driver cannot enable the Fast Writes on your card's BIOS when it loads. I have read archives with many people having that same problem.
The only solutions I found wrt Fast Writes were:
- Edit the os-registry.c file under the kernel's NVdriver home directory before compiling, and re-install (but you — and I — have done that)
- Search for a Nvidia BIOS tool that will enable Fast Writes by default on the BIOS. (have not found one for LINUX, yet! — But maybe you can use one for Windows — if you use Windows)
- Email Nvidia support, and hope they will get back to you. (I have tried it a few times, but they seem to ignore emails) 
Nonetheless, I continue to search once in a while for new drivers/tools for Nvidia cards in LINUX, and If I come across a solution in the next couple of weeks, I will let you know. . .
Sorry I could not be of more assistance. . .

Say's it's supported, but disabled.

Yup
<< Also try different depths when loading X. A small color depth probably does not make use of the Fast Writes, since the driver does not see the use for it.
To find out the depth X is running, type:
xdpyinfo | grep "depth of root"
at the console.

I'm running 24bit color, and the grep command says 24 planes too. If I try and run at 32bit, I get errors saying the driver doesn't support color depths that high.
