Award BIOS Setup Utility
3.1.3.10 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 field must be disabled
to provide contiguous system memory.
3.1.3.11 Delayed Transaction
When enabled, this function frees up the PCI bus for other PCI
masters during the PCI-to-ISA transactions. This allows PCI and ISA
buses to be used more efficiently and prevents degradation of
performance on the PCI bus when ISA accesses are made.
3.1.3.12 Delay Prior To Thermal
This field is used to select the time that would force the CPU to a
50% duty cycle when it exceeds its maximum operating temperature
therefore protecting the CPU and the system board from
overheating to ensure a safe computing environment..
3.1.3.13 AGP Aperture Size (MB)
This field is relevant to the memor y-mapped graphics data of the
AGP card installed in your system. Leave this in its default setting.
3.1.3.14 On-Chip VGA Setting
On-Chip VGA
This field allows you to enable or disable the onboard VGA.
On-Chip Frame Buffer Size
The options are 1MB and 8MB.
Boot Display
This field is used to select the type of display that is connected
to the onboard VGA.
