These options enable shadowing of the contents of the ROM area named in
the option. The ROM area not used by ISA adapter cards is allocated to
PCI adapter cards. The settings are:
Disabled
,
Enabled or Cached
.
When set to
Disabled,
the contents of the video ROM are not copied to
RAM. When set to
Enabled,
the contents of the video ROM area from
C0000h-C7FFFh are copied (shadowed) from ROM to RAM for faster
execution. When set to
Cached,
the contents of the video ROM area from
C0000h-C7FFFh are copied from ROM to RAM and can be written to or
read from cache memory.

SERR# (System Error)
The settings for this option are
Enabled

. Set to
Enabled
to
enable the SERR# signal on the bus. BX asserts this signal to indicate a
system error condition. SERR# is asserted under the following conditions:
- In an ECC configuration, the 82443BX asserts SERR#, for single bit (correctable) ECC errors
or multiple bit (non-correctable) ECC errors if SERR# signaling is enabled via the ERRCMD
control register. Any ECC errors received during initialization should be ignored.
- The 82443BX asserts SERR# for one clock when it detects a target abort during 82443BX
initiated PCI cycle.
- The 82443BX can also assert SERR# when a PCI parity error occurs during the address or
data phase.
- The 82443BX can assert SERR# when it detects a PCI address or data parity error on AGP.
- The 82443BX can assert SERR# upon detection of access to an invalid entry in the Graphics
Aperature Translation Table.
