AGP Command FIFO. This setting allows to you to set the AGP Command FIFO for your Voodoo 4/5 AGP (obviously this setting doesn't effect the Voodoo 4/5 PCI cards). Depending on the card you have installed you should first select the appropriate AGP setting in the BIOS. If you have a Voodoo 5 5500 AGP the highest you can use is AGP 2X (It doesn't support AGP 4X data transfer rates), although the Voodoo 4 4500 & Voodoo 5 6000 AGP do support AGP 4X if available.

Settings available are: Auto Detect. This allows Windows to auto-determine the optimal AGP command FIFO setting for the 3dfx card, generally this would translate into using the highest AGP setting you've selected in your BIOS, e.g. AGP 4X (Except with the Voodoo 5 5500). If you are using an AGP 4X capable slot, along with a Voodoo 4 4500 or Voodoo 5 6000 AGP you should select AGP 4X in the BIOS & select this option.
