Configure BIOS without F2

Hi,
Can someone pls help me on this. I know you guys can configure the BIOS setting by pressing F2 right and then configure the BIOS.

Does anyone have a tool which can set the BIOS settings in DOS mode?
For example, enable USB emulation to "on" in DOS prompt:-

c:\>bios.exe 009B 1

bios.exe will be the dos program
009B will be the example address for the USB
1 is on, while 0 is off.

Is there such a program or can someone pls tell me how can I write my own?

Thanks a lot!

Not personally, but you could take a look at:

Hi Nick,
Thanks for the reply.

I went to the link that you've showed me but it didn't describe on how to change the BIOS setting. For instance, if I were to change the setting in BIOS for the On-Board Sound from Disable to Enable in MS-DOS mode,
is that possible?

Any possible way I can access the BIOS ROM content using C or DOS batch command?

thanks and regards,
yin howe

Ah, I thought you wanted to program the USB.
The layout of CMOS depends on the BIOS maker.

http://irb.cs.uni-magdeburg.de/~zbrog/asm/cmos.html - covers several older BIOSes
A later version is cached on Google.

You can write a Basic or assembler program to read and write the CMOS (I did once a long time ago - I don't know where it is now). Or you could try a Google search for "CMOS utility" and see what you can find.
