cf-28 bios help needed

I have several cf-28pb's and want to remove the booting logo put on by a previous owner but cannot get the bios update to load. I get to the bios updating page then nothing!! Please can somebody help???

 

What is the full model number

I have never had a Toughbook that has a custom logo
That info might be in a permanent section of the bios that will not update or clear when you flash the bios

It is:
CF-28PBJ12FE
3IYAA04294

When i boot from disc and force the programme to run i get to the file load page on the bios updater showing current version 2.00-L12AMM32 but then does nothing???

 

The bios file I found Version: v200L13 is here
http://www.panasonic.ca/PDP/Software/cf28_mk2_v200l13_r-2002-0150.zip

Give that a try
btw is that the update version that you have

I just burn't those file's to cd and the same. All i am doing is typing d:bu28m2 v200l13.282. Is this wrong??

 

I have never updated using a cd ( so i am not sure if that works)
The steps that I use
Update from floppy
Make sure battery and ac adapter are used as it will not update without
Make up floppy with bios file and make it bootable
Or put bios files on disk and use another bootable disk and boot to floppy
Type A:
Put in bios floppy
Enter dir
That lists the files on the floppy
Look for the .exe bios file and enter it

I just typed in d:BU28M2 -d -sn -cn

and it is expecting 13.82-l13m00 ???

 

Type in dir and report list

Alex I believe that you are right the splash screen can't be flashed over with a bios update. Our friend might have to go to the bios mods forum and see if they can help. Pheonix bios' are difficult to modify so if they can't help he may just have to get used to it.

When i type dir i get the list of files on the cd, again i can get the bios updater to run by typing d;bu28m2.exe v200l13.282. but then nothing.
I will go to the other forum also.
Thanks for trying

 

Try
D:V200L13.282
D:V200L13.282.exe
etc ,try different combinations on the bios upgrade files
Best I can do as you did not report the file names found


Alex

 

dir gives:
BU28M2.exe
V200L13.282
ECMOS.exe
autoexec.bat
Have tried
d:bu28m2 v200l13.282 brings on file instal screen then nothing.
I have also found a V201L13.282 but still the same

 

Looks like it's not going to flash
You could try ECMOS.exe
It's been a few years that I have updated the bios on these, the new toughbooks update in windows
