to quote pc_guide

When enabled, this parameter turns on BIOS ROM shadowing for the block of memory that contains your system BIOS. This is normally F0000 to FFFFF (64K). See here for a full description of what ROM shadowing does; in short, it speeds up your system by copying the contents of your system BIOS code from the slow ROM in which it resides into faster RAM.

This setting normally defaults to "Enabled". Since the system BIOS code is used so extensively, shadowing it can cause a great deal of system performance improvement.

Why this is reporting an error i am less clear about.
Infact it is preferable to enable shadowing.
If is does cause an error disable it and see if that helps

Who knows !
Windows pretty much contains its own bios so the PC bios becomes much less important. Once it boots the machine it actually becomes more of a hinderance because it tends to run in an old 8086 compatability mode which can cause problems in windows. The memory hole created by shodowing (copying) the slow flash device into RAM can also cause problems in windows which expects you to have linear memory in one contiguous block without any holes.
