3.3 PCIPnP
3.3.1 Clear NVRAM
Clear NVRAM during system boot.
3.3.2 PCI Latency Timer
Allow you to select the value in units of PCI clocks for all of the PCI device latency timer
register. Configuration option: 32, 64, 96, 128, 160, 192, 224, 248.
Option Description
32 This option sets the PCI latency to 32 PCI clock cycles.
64 This option sets the PCI latency to 64 PCI clock cycles. This is the default setting.
96 This option sets the PCI latency to 96 PCI clock cycles.
128 This option sets the PCI latency to 128 PCI clock cycles.
160 This option sets the PCI latency to 160 PCI clock cycles.
192 This option sets the PCI latency to 192 PCI clock cycles.
224 This option sets the PCI latency to 224 PCI clock cycles.
248 This option sets the PCI latency to 248 PCI clock cycles.
Set this value to allow the PCI Latency Timer to be adjusted. This option sets the latency of all
PCI devices on the PCI bus This decides how long a PCI device can hog the PCI bus for , higher
setting , hogs the bus a little longer , lower setting lets go quicker but stuff like some sound card
(PCI of course) will start to crackle , default on this board was default at 64.
