RAS96 RASCard User Guide CPU Internal Cache/External Cache These two categories speed up memory access when enabled. Enabled Enable cache (Default). Disabled Disable cache. Quick Power On Self Test This category speeds up the power-on self-test (POST) after you power up the computer. If it is set to Enable, BIOS will shorten or skip some check items during POST. Enabled Enable quick POST. Disabled Normal POST (Default).
4 BIOS Setup Utility Gate A20 Option This entry allows you to select how the gate A20 is handled. The gate A20 is a device used to address memory above 1 MB. Initially, the gate A20 was handled via a pin on the keyboard. Today, though keyboards still provide this support, it is more common, and much faster, for the system chipset to provide support for gate A20. Normal Keyboard. Fast Chipset (Default). Memory Parity Check Parity is a method of checking for errors in system memory.
RAS96 RASCard User Guide Typematic Delay (Msec) When the typematic rate is enabled, this selection allows you to select the delay between the first and second characters. 250 250 ms (Default). 500 500 ms. 750 750 ms. 1000 1000 ms. Security Option This category allows you to limit access to the system and to Setup, or just to Setup. System The system will not boot and access to Setup will be denied if the correct password is not entered at the prompt.
4 BIOS Setup Utility Chipset Features Setup This section allows you to configure the system based on the specific features of the installed chipset. The chipset manages bus speeds and access to system memory resources, such as DRAM and the L2 external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. These items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system.
RAS96 RASCard User Guide Video BIOS Cacheable As with caching the System BIOS above, enabling the Video BIOS cache will cause access to video BIOS addressed at C0000H to C7FFFH to be cached, if the cache controller is also enabled. Enabled Video BIOS access cached. Disabled Video BIOS access not cached (Default). 8-Bit I/O Recovery Time The recovery time is the length of time, measured in CPU clocks, which the system will delay after the completion of an input/output (I/O) request.

If Max Power Saving is not enabled, this will be preset to No. Yes APM enabled. No APM disabled. Video Off Method This determines the manner in which the monitor is blanked.
RAS96 RASCard User Guide Power Down Activities Power Down Activities events are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode. In effect, the system remains alert for anything that occurs to a device that is configured as ON, even when the system is in a power down mode. COM Ports Accessed When set to ON (default), any event occurring at a COM (serial) port awakens a system that has been powered down.
4 BIOS Setup Utility PCI Configuration Setup This section describes how to configure the PCI bus system. The PCI bus allows I/O devices to operate at speeds near the speed the CPU itself uses to communicate with its own special components. It is strongly recommended that only experienced users should make any changes to the default settings. Slot (x) Using INT# Some PCI devices use interrupts to signal that they need to use the PCI bus.
RAS96 RASCard User Guide You can select which INT# is associated with each PCI slot and which conventional IRQ is associated with one of the two available INT#s. A setting of NA means the IRQ has been assigned to the ISA bus and is not available to any PCI slot. PCI IRQ Activated by This item sets the method by which the PCI bus recognizes that an IRQ service is being requested by a device. Under all circumstances, you should retain the default configuration unless advised otherwise by Multi-Tech.
