Bios Mods -The Best BIOS Update and Modification Source

Hello all,

I would like to use the RW Everything tool to automatically change a bit from a 0 to a 1 in my CPUs clock generator each time the computer turns on so I don’t have to do it manually. I understand that there is a command line inside the RW everything tool for loading a file with the custom changes, however I cannot get this right. It seems my clock generators info is stored in Block D2 of my SMBus, and the bit I’m looking to change is the 2nd bit of the 2nd byte from a 0 to a 1. I can not find any documentation for using this tool online, so I figured I’d ask on the forum where I first found it, does anyone know the correct command for doing this?

Any ideas anyone? This is my coded attempt to use the RW Everything tool command line: Read SMBus D2 0 2. This command writes out nothing, has anyone got experience using this program that can help?

Read Everything's internal help: Access->Command and Access->Command Line

Yes I have been following their documentation, however the program does nothing when I enter the command for reading/writing to the SMBus.

It doesn't match their documentation. Reread it.

My bad, I wasn’t at my computer when I posted that, the Code is Read SMBus Block D2 0 1. The offset parameters are what is throwing me off, whatever format I enter for them I get no result. Are you able to write and example of the working function that I can copy?

SMBUS <Read/Write> <Byte/Word/Block> <Address> <StartOffset> <EndOffset>
Use 0x prefix for hex

See this link for my result https://imgur.com/Gcy8Tdg
The tool is not writing any response to the command to the command line whether I tell it to read or write.
Here is the address I want the script to change : https://imgur.com/qs5f5W8
As you can see in the bottom left, the address of the SMBus is D2. I would like to change byte 0x1 from a "83" to a "C3".

Try
SMBUS Read Byte 0xD2 ... etc
Show a screenshot of SMBus Device with selected required byte.

That seems to have worked in reading the first two bytes: https://imgur.com/Ob4pCEZ
However I don't seem to be able to use the Write function correctly: https://imgur.com/BvmY798
In the top line I am trying to write the bytes "91" & "C3" to the first to bytes, but when reading it back it didn't seem to work.
