Description
When synchronous DRAM is installed, the number of clock
cycles of CAS latency depends on the DRAM timing.
and RAS strobe signals, used when DRAM is written to,
read from, or refreshed, Fast gives faster performance; and
Slow gives more stable performance. This field applies only
when synchronous DRAM is installed in the system.
If an insufficient number of cycles is allowed for the RAS to
accumulate its charge before DRAM refresh, the refresh
may be incomplete and the DRAM may fail to retain data.
Fast fives faster performance; and Slow gives more stable
performance.This field applies only when synchronous
DRAM is installed in the syste.
This option is used to set up the timing delay between the
SDRAM active to precharge.
This option is used to set up e the Refresh Mode
This option is used to select the video mode.
Select the on chip memory size for VGA drive use.
