Award BIOS Setup Utility
Memory Hole At 15M-16M
In order to improve system performance, certain space in memory
can be reserved for ISA cards. This memory must be mapped into
the memory space below 16MB. When enabled, the CPU assumes
the 15-16MB memory range is allocated to the hidden ISA address
range instead of the actual system DRAM. When disabled, the CPU
assumes the 15-16MB address range actually contains DRAM
memory. If more than 16MB of system memory is installed, this
option must be disabled to provide contiguous system memory.
PCI 2.1 Compliance
By default, this field is Disabled. However, if you encounter problems
with your PCI card, try setting this field to Enabled. It may be that
your card is PCI 2.1 compliant.
AGP Aperture Size (MB)
This field is relevant to the memory-mapped graphics data of the
AGP card installed in your system. Leave this in its default setting,
which is 64MB.
CPU/PCI Clock (MHz)
This field is used to select the external system bus clock of your
processor. The options are Default, 66.8/33.4, 75/37.5, 83.3/
41.65, 100.3/33.4, 103/34.33, 105/35, 110/36.67, 112/37.33,
115/38.33, 120/40, 124/31, 124/41.33, 133/33.25, 133/44.33,
140/35 and 150/37.5. When selecting the external bus clock of
your processor, the PCI clock will at the same time appear next to
the external bus clock selected. For example, if you selected 66.8/
33.4, 66.8MHz is the external bus clock and 33.4MHz is the PCI
clock. Regardless of the type of processor used, the default setting
is Default. Under this setting, the system will run according to
the processors clock frequency. If you selected an option other
than Default and is unable to boot up the system, there are 2
methods of going back to its default setting.
Method 1:
Clear the CMOS data by following the procedure in section 2.5
(chapter 2) of this manual. All fields in the BIOS Setup will
automatically be set to its default settings.
