Phoenix MicroATX Express – Installation Guide
Yes The Yes setting allows the operating system to change the interrupt, I/O, and DMA settings. Set this option if the
system is running Plug and Play aware operating systems.
PCI Latency Timer
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. The Optimal and Fail-Safe default setting is
64 .
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.
Allocate IRQ to VGA
Set this value to allow or restrict the system from giving the VGA adapter card an interrupt address. The Optimal
and Fail-Safe default setting is
Yes.
Yes Set this value to allow the allocation of an IRQ to a VGA adapter card that uses the PCI local bus. This is the
default setting.
No Set this value to prevent the allocation of an IRQ to a VGA adapter card that uses the PCI local bus.
Palette Snooping
Set this value to allow the system to modify the Palette Snooping settings. The Optimal and Fail-Safe default setting
is
Disabled .
Disabled This is the default setting and should not be changed unless the VGA card manufacturer requires Palette
Snooping to be Enabled.
Enabled This setting informs the PCI devices that an ISA based Graphics device is installed in the system. It does this
so the ISA based Graphics card will function correctly. This does not necessarily indicate a physical ISA adapter card.
The graphics chipset can be mounted on a PCI card. Always check with your adapter card’s manuals first, before
modifying the default settings in the BIOS.
PCI IDE BusMaster
Set this value to allow or prevent the use of PCI IDE bus mastering. The Optimal and Fail-Safe default setting is
Disabled .
Disabled Set this value to prevent PCI bus mastering. This is the default setting.
Enabled This option specifies that the IDE controller on the PCI local bus has mastering capabilities.
OffBoard PCI/ISA IDE Card
Set this value to allow the OffBoard PCI/ISA IDE Card to be selected. The Optimal and Fail-Safe default setting is
Auto .
Auto This setting will auto select the location of an OffBoard PCI IDE adapter card. This is the default setting.
PCI Slot1 This setting will select PCI Slot 1 as the location of the OffBoard PCI IDE adapter card. Use this setting
only if there is an IDE adapter card installed in PCI Slot 1.
PCI Slot2 This setting will select PCI Slot 2 as the location of the OffBoard PCI IDE adapter card. Use this setting
only if there is an IDE adapter card installed in PCI Slot 2.
