Scroll to the bottom Supermicro P6SNF the Resource Supermicro P6SNF box and you will see a line that reads: The first value is the location of the linear frame buffer. For all three, 0 disables, 1 enables, any other value results in no change from the current setting.

N indicates the amount of video memory in MegaBytes. Valid values are 2, 4, and 8. Also valid are -2, -4, and -8 to apply the special "vertical stripe" patch. It will also tell you what the equivalent command line is for the options you chose. The "" setting simulates Supermicro P6SNF A2 motherboard where Write Posting is disabled.

The above are all Supermicro P6SNF applications. If you have an A2 motherboard turning on write posting will increase the WinBench96 Graphic Winmark score by about 25 percent. One example is using the Media Player to play an animation to a high resolution, highcolor or truecolor window. Run Win95 in a high resolution, direct color mode; say x, 24bits per pixel.


Start the Media Player. Enlarge the playback window to nearly full screen do not use the Supermicro P6SNF Player's "full screen" option -- if you do it will change the screen to a lower resolution 8 bit mode for Supermicro P6SNF. Press the Play button. With write posting and write combining turned off you will get very poor results, about 2 frames per second. With write posting on and write combining off that will improve to about 4 frames per second.

With both write posting and Supermicro P6SNF combining on you will get very smooth playback with the frame rate too fast to count. You can see similar affects with the Hover! Again, with Win95 in a hires direct color mode, enlarge the Supermicro P6SNF window as large as it will let you about x With write posting and write combinging off you will get poor performance.

With write posting Supermicro P6SNF the game will be playable. With write posting and write combining the action will Supermicro P6SNF very smooth. If you have a pre-B0 motherboard you can still benefit from write combining without fear of encountering the bugs in the above DOS and Win95 situations.

Write Posting is where the processor "posts" data to the PCI bus and then goes on it's way without waiting for the write operation to complete. Because of bugs in the pre-B0 stepping of the Supermicro P6SNF Write Supermicro P6SNF is disabled on early Pentium Pro motherboards.

You don't want to do this routinely because the bugs in the chipset will eventualy cause the PCI bus to hang, forcing Supermicro P6SNF reboot of the machine. Motherboards Supermicro P6SNF the B0 stepping have this bug fixed and Write Posting enabled by default. This function allows seperate writes to the banked VGA mechanism to be combined into a cacheline that can be bursted out to video memory via the PCI bus.

Supermicro Motherboard Memory

I believe this used to be handled in hardware but Intel decided to make it a programable function with the Pentium Pro to make the motherboard architecture more general. Many newer graphics cards have their graphics memory mapped linearly at very high physical addresses in addition to the banked VGA mechanism at A The reason for doing this is to make Supermicro P6SNF to video memory simpler and faster -- programs and Windows drivers don't have to switch banks all the time to access all of video memory. Again, this was Supermicro P6SNF to generalize the motherboard design.


You can theoretically have multiple devices mapped in high address space with different cachability options. Supermicro P6SNF believes that proper place for this to be handled is within a PNP operating system.

Unfortunately, no operating system yet supports this. SUPER P6SNF Supermicro, Motherboard, mainboard, chipset, základní desky, Slot, Socket, information.
