DRAM RAS# Activate to Precha [15 DRAM Clocks]
Use the DRAM RAS# Activate to Precha option to specify the length of the delay
between the activation and precharge commands for the RAS signal. That is how long
after activation can the access cycle be started again. This influences row activation time
that is considered when memory has hit the last column in a specific row, or when an
entirely different memory location is requested. (To be able to change this configuration
option the Configure DRAM Timing by SPD configuration option must be set to
“ Disabled ”) The following configuration options are available:
9 DRAM Clocks
10 DRAM Clocks
11 DRAM Clocks
12 DRAM Clocks
13 DRAM Clocks
14 DRAM Clocks
15 DRAM Clocks D
EFAULT
Memory Hole [Disabled]
Use the Memory Hole option to reserve memory space between 15MB and 16MB for ISA
expansion cards that require a specified area of memory to work properly. If an older ISA
expansion card is used, please refer to the documentation that came with the card to see if
it is necessary to reserve the space.
Disabled D
EFAULT
Memory is not reserved for ISA expansion cards
15MB – 16MB Between 15MB and 16MB of memory is reserved for
ISA expansion cards
Initiate Graphics Adapter [PEG/PCI]
Use the Initiate Graphics Adapter option to select the graphics controller used as the
primary boot device. Select either an integrated graphics controller (IGD) or a combination
of PCI graphics controller, a PCI express (PEG) controller or an IGD. Configuration
options are listed below:
