From sp41954 v4.78 I think ...

 

Is it the same original error message ?

To everyboy please post the error messages exactly , so I can follow them

 

Hello mutante.

The original message for SP41954.exe (rompaq.exe v4.78) is:

Code:

c:>rompaq /u
Reading file...
(here some seconds of process)
Error in file content from disk.
Please try recreating file or disk.
c:>

 

Ok thank you, and if you use my rompaq_ the message is the same?

 

I'll try your rompaq in 2 or 3 hours at home. I'll report my results ASAP

Thanks mutante...

Maybe can you use /u switch. I think it's easer for mutante to follow code without graphical interface.
Try rompaq /u

Hi again Mutante.

So, I boot with a UsbKey and type rompaq /U
I have a new message...

Code:

C:>ROMPAQ /U
Reading file...
(some seconds)


The code used to verify the integrity of your BIOS does not
match what is currently on your system.  This could cause
parts of the BIOS to be skipped when updating leading to
unpredictable results including failure to boot.  It is very
strongly recommended that you not proceed with the update.


Press
F10=Continue, ESC=Cancel

Can you confirm me that is the message you except (following dissassembly code). If you're OK, I'll press F10... (and pray)...

Thanks mutante

 

I pressed F10, updating ROM starts..., and SLIC 2.0 after after reboot

 

Rompaq usage

usage: Rompaq [/D] [/U] [/B] [/R] [/X] [/C | /!] [/P xx.bin]
where: /D = Dock (operation applies to docking station)
/U = Update System BIOS with new version
/B = Backup BIOS (save to disk)
/R = Restore BIOS (program with backup image)
/X = reset CMOS/ECMOS to factory defaults
/F = force docking station recovery
/C = do not allow exit to DOS (power cycle)
/! = do not allow exit to DOS (power off)
/P xx.bin = admin password is read from encrypted file xx.

 

Did you know where are they?

Hummm I can't understand why is not working "in memory patch", have to think a follow code ...

 

So if you BIOS has two SLIC's we still can't patch it?

If you have one SLIC we can with the method below? Has this been confirmed to work?

1. take the original sp41953
2. launch the hpqflash.exe and press "Next"
in HxDEN: open RAM and load HPQFlash.exe
3. search and replace the original slic parts on parts of slic2.1 (see Attached Thumbnails)
4. save changes
5. in HPQlash windows press "Next" -> updating ROM starts
after rebooting SLIC 2.0.

From @andmail, can someone please explain step 3? Bit of a n00b when it comes to this.

Thanks guys
