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

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

RU v4.94 beta

1. Fixed search function failed to display the correct position
2. Remove obsoleted auto SIO detect
3. Add HDD info: TCG feature set and SSD
4. Add displaying ACPI tables (ALT-6), still under testing.

Please leave a comment if I created more bugs in this version! XD

RU v4.93

Major features:

1. Added support to identify AHCI devices.  Note: Only one platform is tested.
2. IDE detection is changed to list all the devices found.  User does not need to select the controller and device now.  The UI has the same look as PCI device selection screen. (Notes: Multiple controllers are not tested.)

Minor bug fixes:

1. Fixed read/write UEFI variables not working for PI1.2
2. CTRL-G will go to 32-bit memory address read from current position if it is not a RU recognized address by default.
3. Fixed compare file is not working.
4. Fixed search may not display the value correctly if many occurrences in the same page.  Usually happened with 1 digit hex search.
5. Add IDE words 128-255 details and works with page 2
6. BBS header and IPL entries are separated for SHIFT-F5.
