Report No FDD for Win95
Select Yes to release IRQ6 when the system contains no floppy drive, for compatibility with
Windows 95 logo certification. In the Integrated Peripherals screen, select Disabled for the
Onboard FDC Controller field.
You should choose “Yes” if your operating system is Windows
95 and without a floppy disk equipped in your computer.
The choice: Yes/No
Shadow
Software that resides in a read-only memory (ROM) chip on a device is called “firmware”. The
AwardBIOS permits shadowing of firmware such as the system BIOS, video BIOS and similar
operating instructions that come with some expansion peripherals, such as, for example, a SCSI
adapter.
Shadowing copies firmware from ROM into system RAM, where the CPU can read it through
the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by system through the
8-bit X-bus. Shadowing improves the performance of the system BIOS and similar ROM
firmware for expansion peripherals, but it also reduces the amount of high memory (640 KB to 1
MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Video BIOS shadows into memory
area C0000-C7FFF. The remaining areas shown on the BIOS Features screen may be occupied
by other expansion card firmware. If an expansion peripheral in your system contains
ROM-based firmware, you need to know the address ranges the ROM occupies to shadow it into
the correct area of RAM.
Video BIOS Shadow
Determines whether video BIOS stored in the ROM of the video card will be copied to system
RAM for speeding up the execution. Video BIOS Shadow will increase the video performance.
Enabled
Video BIOS shadow is enabled
Disabled
Video BIOS shadow is disabled
C8000 - CBFFF Shadow to DC000 - DFFFF Shadow
These categories determine whether BIOS of expansion interface cards located with these
memory address ranges will be copied to system RAM for improving the performance. An
example of such an option would be on-board SCSI.
Enabled
Optional shadow is enabled
Disabled
Optional shadow is disabled
