MA Wait State
Select the wait state before the beginning of a memory
read. The default settings is Slow.
EDO RAS# To CAS# Time
This field applies only if EDO DRAM is installed in the
system. It lets you insert a timing delay between the CAS
and RAS strobe signals, used when DRAM is written to,
read from, or refreshed. The default setting is 3.
EDO RAS# Precharge Time
The precharge time is the number of cycles it takes for the
RAS to accumulate its charge before DRAM refresh. If
insufficient time is allowed, refresh may be incomplete
and the DRAM may fail to retain data. This field applies
only if EDO DRAM is installed in the system. The
default setting is 3.
EDO DRAM Read Burst
Set the timing for burst-mode reads from DRAM. The
lower the timing numbers, the faster the system addresses
memory. This field applies only if EDO DRAM is in-
stalled in the system.
EDO DRAM Write Burst
Set the timing for burst-mode writes from DRAM. The
lower the timing numbers, the faster the system addresses
memory. This field applies only if EDO DRAM is in-
stalled in the system.
DRAM Data Integrity Mode
Select Parity or ECC (error-correcting code), according
to the type of installed DRAM.
