Delayed Transaction - Abit LM6E Pentium II User Manual

3-20
16 Bit I/O Recovery Time:
Five options are available: NA $ 4 $ 1 $ 2 $ 3 $
option specifies the length of a delay inserted between consecutive 16 bit I/O
operations. For an earlier 16 bit Add-on card, sometimes you need to
adjust its recovery time to make it work normal.
Memory Hole At 15M-16M:
This option is used to free up the 15M-16M memory block. Some special
peripherals need to use a memory block located between 15M and 16M, and
this memory block has a size of 1M. We recommend that you disable this
option.
Passive Release :
Two options are available: Enabled and Disabled. Set the option to enabled
or disabled passive release for the Intel PIIX4 chip (Intel PCI to ISA bridge).
This function is used to meet the latency of the ISA bus master, if you have
an ISA card compatibility problem, you can try to enable or disable this
option for optimal result.

Delayed Transaction:

Two options are available: Enabled and Disabled. Set the option to
enabled or disabled delayed transaction for the Intel PIIX4 chip. This
function is used to meet the latency of PCI cycles to or from the ISA bus.
This option must be enabled to provide PCI 2.1 compliance. If you have
ISA card compatibility problem, you can try to enable or disable this option
for optimal result.
AGP Aperture Size (MB):
Seven options are available: 4 $ 8 $ 16 $ 32 $ 64 $ 128 $ 256 $
. This option specifies the amount of system memory that can be
Back to 4
used by the AGP device. The aperture is a portion of the PCI memory
address range dedicated for graphics memory address space.
SDRAM RAS-to-CAS Delay:
Two options are available: Slow or Fast. This option specifies the length
of the inserted between the RAS and CAS signal of the DRAM system
memory access cycle if SDRAM is installed. The setting will affects
SDRAM performance, the default setting is Slow.
