1-20
deactivates IDE 1 but frees IRQ 14 for the use of other devices. The default
setting is Enabled.
Onboard IDE Secondary Channel
This parameter allows you to enable or disable the onboard IDE secondary
channel controller. Setting this parameter to Enabled lets you use the
secondary IDE connector (IDE 2) to connect up to two IDE drives. Setting to
Disabled deactivates IDE 2 but frees IRQ 15 for the use of other devices. The
default setting is Enabled.
Memory/Cache Options
The Memory/Cache Options menu allows you to configure the Level 1 and
Level 2 caches. Enabling the cache parameters optimize system
performance.
Some older applications, however, may not run properly with the caches
enabled. Set the parameters to Disabled when you run these applications.
Disabling the caches will degrade system performance.
PnP/PCI Options
The parameters in the PnP/PCI Options menu allow you to set the IRQ
assignments for your PCI devices.
PCI IRQ Setting
This parameter allows for automatic or manual configuration of PCI devices. If
you use Plug and Play devices, you can keep the default setting Auto. The
system then automatically configures the Plug and Play devices. If you install
non-Plug and Play adapter cards, set this parameter to Manual. This allows
you to assign resources to non-Plug and Play cards first.
PCI IRQ Sharing
When set to Yes, this parameter allows you to assign the same IRQ to more
than one PCI device installed in the system. When set to No, you must assign
different IRQs to the PCI devices. The default setting is Yes.
VGA Palette Snoop
The VGA palette snoop function allows the system to refresh all ISA and PCI
graphic adapters installed in the system. This is needed if you install an
additional graphics overlay card such as an MPEG or an advanced 3D
graphics adapter. If the image on your monitor has problems after installing
such an adapter, set this parameter to Enabled. Otherwise, leave it to the
default Disabled to achieve better performance.
