SDRAM CAS LATENCY TIME:
When synchronous DRAM is installed, the number of clock cycles of CAS
latency depends on the DRAM timing.
SDRAM CYCLE TIME TRAS/TRC:
This item set the number of SCLKs for an access cycle.
SDRAM RAS-TO-CAS DELAY:
This item let you insert a timing delay between the CAS 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.
SDRAM RAS PRECHARGE TIME:
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 gives faster performance; and Slow gives more
stable performance. This field applies only when synchronous DRAM is
installed in the system.
SYSTEM BIOS CACHEABLE:
This item allows you to enable caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance. However, if any program
writes to this memory area, a system error may result.
VIDEO BIOS CACHEABLE:
This item allows you to enable caching of the video BIOS, resulting in better
system performance. However, if any program writes to this memory area,
a system error may result.
MEMORY HOLE AT 15M-16M:
You may reserve this area of system memory for ISA adapter ROM. When
this area is reserved, it cannot be cached. The user information of
peripherals that need to use this area of system memory usually discusses
their memory requirements.
