Video BIOS access cached 

Video BIOS access not cached 

 

Video RAM Cacheable:   

Select Enabled allows caching of the video RAM , resulting in 

better system performance. However, if any program writes to this 
memory area, a system error may result. 

 

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 
request. This delay takes place because the CPU is operating so 

much faster than the input/output bus that the CPU must be 
delayed to allow for the completion of the I/O. This item allows you 

to determine the recovery time allowed for 8-bit I/O. The available 

choices are from NA, 1 to 8 CPU clocks. 

 

16 Bit I/O Recovery Time:  

This item allows you to determine the recovery time allowed for 

16-bit I/O. The available choices are from NA, 1 to 4 CPU clocks. 

 

Memory Hole At 15M-16M:   

In order to improve performance, certain space in memory can be 

reserved for ISA cards. This memory must be mapped into the 

memory space below 16 MB. 

Memory hole supported 

Memory hole not supported 

 

Passive Release:   

When Enabled, CPU to PCI bus accesses are allowed during 

passive release. Otherwise, the arbiter only accepts another PCI 
master access to local DRAM. The available choices are Enabled, 

Disabled. 

 

Delayed Transaction:   

The chipset has an embedded 32-bit posted write buffer to 

support delay transactions cycles. Select Enabled to support 

compliance with PCI specification version 2.1. The available 
choices are Enabled, Disabled. 

 

Select the size of the Accelerated Graphics Port (AGP) aperture. 
The aperture is a portion of the PCI memory address range 

dedicated for graphics memory address space. Host cycles that 

hit the aperture range are forwarded to the AGP without any 
translation. See www.agpforum.org for APG information. The 

available choices are 16 MB, 32 MB, 64 MB, 128 MB, and 256MB.
