received by the DRAM controller. When it is enabled, the controller will issue the read
command slightly before it has finished determining the address.
System BIOS Cacheable - When Enabled , the Video BIOS cacheable will cause access to
the System BIOS addressed at F0000H to FFFFFH to be cached. * Disabled is the default.
Video BIOS Cacheable - When Enabled , the Video BIOS cacheable will cause access to
the video BIOS addressed at C0000H to C7FFFH to be cached. * Enabled is the default.
8 Bit I/O Recovery Time - The recovery time is the length of time, measured in CPU
clocks, that the system will delay after the completion of an input/output request. This delay
takes place because the CPU is operating faster than the input/output bus. Therefore the
CPU must be delayed to allow for the completion of I/O transfers. This item allows you to
determine the recovery time allowed for 8 bit I/O. Choices are from NA, 1 to 8 CPU clocks.
*
1 is the default.
16 Bit I/O Recovery Time - Same with 8 Bit I/O Recovery Time, this item allows you to
determine the recovery time allowed for 16 bit I/O. Choices are from NA, 1 to 4 CPU
clocks. *
1 is the default.
Memory Hole At 15M-16M - In order to improve compatibility, certain space in memory
can be reserved for old style ISA cards that map memory between 15M-16M. Do not enable
this feature unless you use the old style ISA card, otherwise the memory size may be
reduced to 15 MB for some operating systems. *
Disabled is the default.
PCI 2.1 Compliance - It is used by targets that cannot complete the initial data phase
within the requirements of the PCI 2.1 specification. Disabled is the default.
Auto Disable Unused Clock - When enabled, any clock not in use will be disabled to
reduce EMI radiation.
CPU Overheat Alarm ( > 65
°°
C) - When Enabled , once the CPU temperature exceeds
65
°
C, a warning will be issued via the speaker and the operating CPU speed will be slowed
down to ease the situation.
CPU Fan Malfunction Alarm - When Enabled , the system will issue a warning via the
speaker when the CPU fan starts to malfunction.
System 5V Alarm ( < 4.7V) - When Enabled , you will be warned via the speaker if the
system board operating voltage is below 4.7V.
