Setting Chip Set Feature Control Options
The second screen of the SETUP program contains the options
related to the features on your system board. Press PgUp or
PgDn
to display this screen.
Relocating memory
The Relocate Memory option relocates the memory between
A0000h to BFFFFh and D0000h to EFFFFh for use as extended
memory. If you enable shadowing, however, relocation is
automatically disabled.
Shadow RAM options
Your computer can access RAM (random access memory) faster
than ROM (read only memory).
Two shadow features (Shadow BIOS ROM and Shadow Video
ROM
) allow your system to copy the contents of its system and/or
video ROM into RAM so it can perform certain operations faster.
You can also shadow 32KB or 64KB of memory that starts at the
indicated addresses to RAM. If you enable these options, you
cannot use the Relocate Memory feature.
Additional options
Two additional chipset feature options allow you to slow down
your system in case you need compatibility with slower option
cards or diskette drives.
If you enable the ISA 1 wait state option, the system
inserts one wait state in a 16-bit ISA cycle rather than providing
the
fastest processing at zero wait states.
The Slow Refresh option, when enabled, improves system
performance because it shortens the time needed for each
refresh cycle.
