DRAM CAS# Latency [By SPD]
Use the DRAM CAS# Latency option to set the CAS (Column Address Strobe) latency.
The CAS latency is the number of clock cycles (or Ticks, denoted with T) between the
receipt of a "read" command and when the RAM chip actually starts reading. The BIOS
options are as follows:
By SPD (Default)
2T
2.5T
3T
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
