SMBUS will be rewritten

The SMBUS function of RU is lame.  I will start to rewrite SMBUS part when I had time to do it.  May not be soon but I will take this as a priority.

RU.EFI v4.95

Finally I have done a test beta version of RU for UEFI after adding all those functions in assembly/DOS back and resolving thousands of compiler errors.

I am glad that the life of this ancient BIOS tool still last even in the UEFI era!

This version is synchronized with DOS RU 4.95.  It should have almost all the features that DOS RU has.  However reading/writing UEFI variables are not supported for now because I think using dmpstore would be easier than RU :)

Known issues:

Accessing MSR may not work on all platforms, it depends on if your BIOS implemented specific UEFI functions fully.  If it doesn't accessing MSRs may hang.  MSR for IA32 is not implemented yet.

2012/07/11 updated:

This version has a bug that it will not write PCI registers.   It is fixed and will be put to next release.

Try out UEFI beta version here:

RU.EFI = X64 version
RU32.EFI = IA32 version

Old versions of RU.EXE

Here are links to some old versions, please let me know if you need other older version.


Older versions of RU.exe 4.81 to 4.95 can be got here.

Please go to tag: release to get latest versions.

RU for UEFI - Coming soon!

Finally!

I am writing the UEFI version of RU.  The user interface is 99% the same.  Only difference is that some colors may not be the same to DOS version.  This is due to UEFI background color can't have bright attribute.

After fixing thousands of build errors converting DOS version C files, following functions are working now:

• PCI
• IO
• memory
• SMBIOS
• ACPI tables

It's released!! See here
