Маленькое пояснение - вообще-то бОльшая часть кода системного BIOS'а выполняется из ОЗУ. Понятие "затенение" - "shadowing" используется для видеоBIOS'а, причем он может затеняться по частям. Выгоды от затенения видеоBIOS'а можно получить только в тех ОС, которые работают с видеокартой через интерфейс функций, предоставляемых видеоBIOS'ом (т.е. DOS-подобные). BSOD'ов при обращении к "затененной" области нет. Нормальные программы сначала получают у ОС разрешение использовать некоторый диапазон адресов, а затем работают с ним. ОС, соответственно, хранит карту распределения памяти и разрешает использование только свободных участков. Тем более, что для "затенения" используется область около 8 кбайт в старших адресах первого мегабайта памяти. Практически ни одна программа для современных ОС не лезет в этот диапазон адресов .

SUMMARY
Some computers provide a ROM BIOS shadowing option. While this feature provides an advantage with Microsoft MS-DOS, it is not an advantage with Microsoft Windows NT.
MORE INFORMATION
ROM BIOS shadowing is the process of copying the BIOS from ROM into RAM and using either hardware or 386 enhanced mode to remap the RAM into the normal address space of the BIOS. Because reading RAM is much faster than reading ROM, BIOS-intensive operations are substantially faster. For example, MS- DOS uses the BIOS to write to the screen; therefore, with ROM BIOS shadowing, directory listings run more quickly.

Windows NT does not use the BIOS (except during startup); therefore, no performance is gained by shadowing. If ROM BIOS shadowing is not used, more RAM is available. With Windows NT, there is an advantage to disabling the ROM BIOS shadowing option.

This applies to other BIOS shadowing schemes as well. Typically the CMOS settings allow the system to shadow any BIOS. This includes the following:
System BIOS
Video BIOS
Other adapters ROM BIOS (in a given select range)

Most BIOSes have several settings for shadowing each of the 16K blocks of RAM from C8000h through DFFFFh. These settings show up as something like "C8000-CBFFF Shadow", "CC000-CFFFF Shadow", etc., up to "DC000-DFFFF Shadow". Some systems have settings for ROM shadowing in 32K blocks instead of 16K, so you will see "C8000-CFFFF" instead of "C8000-CBFFF" and "CC000-CFFFF". (Some systems leave off the last digit in their notation, calling the blocks "C800-CBFF", etc. It's the same thing.)....

The areas of memory from C8000 to DFFFFh are normally used by expansion cards such as network adapters. Turning on shadowing would speed these adapters up in the same way that shadowing the system BIOS speeds up the system BIOS code. However, things are much more tricky here, because some adapters use RAM as well as ROM, and map this RAM into this address space as well. If they do, and you enable shadowing, the adapter will malfunction because shadowing write-protects the RAM it uses (since it thinks it is emulating a ROM only, which cannot be rewritten). This can cause spurious results when using these cards, and can be very difficult to diagnose. In addition, normally unused areas of memory in this region are used as UMBs for loading drivers via the EMM386 driver, and enabling shadowing will cause this to malfunction.

For this reason, the default for shadowing these adapter ROM areas is normally "Disabled" and I recommend that it be left that way in most cases. If you know all the details on the card whose ROM you are trying to shadow, enabling this can in theory increase performance, but it is not going to be anything very substantial in most cases. Incidentally, on most IDE/ATA systems, the block from C8000 to CBFFFh is reserved by the IDE hard disk BIOS.
