Tips: ENTER / ALT-L

You can press ENTER or ALT-L to List and choose registers details like below snapshots.  You can see the registers listed with explanation.  Not only you get more readable list but also you can select the register you want to go.

Take SMBIOS as an example

ALT-L: You will see the SMBIOS type 0 in details

RU 5.07.0134

RU.EFI only (asked by chrisdar)

• Add support to read/write AP's MSR.
• Ctrl-PgDn and Ctrl-PgUp selects CPU number.
• This feature is NOT TESTED!  This is a test version only.

 Minor changes:

1. Few AHCI MMIO bugs fixed.
2. Fixed divided overflow if user selects CPU MSR from current ACPI page  (reported by snow liu)
3. Display a "please wait..." window while saving RU.SET.
4. Fixed RU32.EFI displaying nothing in register area.
5. Fixed RU32.EFI displaying overflowed memory and IO base addresses.

RU.EFI RU.EXE 5.06.0126 Beta

Main feature:

1. RU.EFI now remembers where you were last time you quited like RU.EXE does.  You don't need to re-configure the registers every time when entering RU.EFI.
2. AHCI MMIO added (Ctrl-F5).  Select 32 ports by PgUp and PgDn.
3. Alt-M is added to select for current type.  For examples, select AHCI port number when you are in AHCI MMIO, select SMBIOS handle number when you are in SMBIOS.
4. Search UEFI variable directly when Alt-= is pressed, you don't need to browse them by arrow keys.  However if the variable name is not found it will list all variables as usual for you to select.
5. RU saved register file format is changed to version 2: no index. Ex: "00=00 01=FF 02=AE" changed to just "00 FF AE".  This also means that you can't load/compare older saved register file in new RU.

 Minor changes:

1. Fixed RU.EFI hangs while accessing some VGA devices.
2. Fixed not displaying the register help for ACPI tables.
3. Added ACPI FACS table.
4. Fixed RU.EXE changes to ISA after UEFI variable type is selected.
5. Fixed shift+value is not working while inputing values.
6. Added support for ACPI load/save/compare.
7. RU.EFI: System Info (Ctrl-I) now displays available memory.
8. Fixed compare file in CPU MSRs messed up at the end of file.
9. Fixed load/compare register file hangs the system.
10. Fixed SMBIOS handle is not displayed correctly when change to different handle number.
11. Fixed Ctrl-W write LBA data hangs the system. 
12. Fixed can't see text after exited RU in Shell 2.0.

Again, any changes will cause bugs.  It's not guaranteed that you can always read/write correct registers using RU.  But please report bugs to me if you found any.

RU.SET? Black screen? Hang?

When you quit RU it will save your current setting to a file called RU.SET.  So every time you execute RU it will stay as where you were last time, you don't need to select the register that you were reading.

However sometimes RU did not check the RU.SET carefully and this will often cause data corruption.

If RU hangs at the beginning, it's  probably caused by wrong data of RU.SET.  You can delete the RU.SET and try to execute RU again.

RU.EFI did not have this file saved, so it did not remember where you were.  The next version of RU.EFI will add this support as RU.EXE does.

Updated: RU.EFI now saved RU.SET as well started from 5.06.0125
