Help with Sideband Addressing and Fast-Writes

I currently have an ASUS V7100 GeForce2 MX on a MSI K7T Turbo mobo. When I run Sisoft Sandra, it informs me that I have both Sideband and Fast write Support, but that neither are enabled. I have fast writes enabled in my BIOS and have tried both nVidia's and ASUS's drivers V45.23. Anyone have any Ideas?

unless you know that the BIOS supports enabling them or that the hardware is really present, you won't be able to. on top of that, you also have to confirm that what SiSoft Sandra calls FastWrite and what the BIOS calls FastWrite are the same thing.

NV11-GPUs (= GeForce 2 MX) do NOT support AGP-sidebanding.
But, you can enable AGP-fastwrites:

what you need is
- a Motherboard (BIOS) which is capable of supporting AGP-fastwrites
- a boot-disk
- NVflash.exe & Dos4gw.exe (from NVidia or ASUS-Homepage)
- X-Bios Editor
- Rivatuner
- a BIOS-file for your VGA-card, for example from
- failing that, make a backup-copy of your VGA-BIOS using NVflash.exe -b and work with that

what to do:
- make sure Fastwrites are enabled in your Motherboard-BIOS
- copy NVflash.exe & Dos4gw.exe to your boot-disk
- install X-BIOS Editor
- install Rivatuner
- edit your VGA-Bios-file with X-BIOS and uncheck the box 'FW Disabled'
- save the modified BIOS-file to boot-disk (newbios.rom)
- boot from the disk and type a:\nvflash -f newbios.rom
- reboot and in windows tell Rivatuner to force Fastwrites. Finished!

You can also do the same precedure to enable AGP-sidebanding if you're using a different GPU to a NV 11 GeForce 2 MX.

Greetings, Seb.
