Re: Panasonic CF53 MK4 CF-532S74RMG

hello,

at the book are label: CF-532S74RMG with serial: 5JTCA29901

as I buy it there was in BIOS (V4.00L18 M91 the Serial: 5KTCA37037

so I think there was some mod before me and the WWAN and WLAN does not work. Wireless switch was disabled and not working (also LED still off).

I search a lot of ROM here and test...a lot of them enables the wireless switch but only WWAN comes on

here the original backup ROM from book at first day (with PW and wireless switch disabled!).

with kind regards

Mike

hello,

yes, the mechanical switch at side of book is on and also the LED is working. With switch I can enable WWAN on/off or like it called "flightmode on/off". So it seems to be ok.

Still the WLAn card's will not regonize in any way, not bios, not windows. In BIOS I have menu for WWAN (enable/disable) but nothing for WLAN, thats curiouse

with kind regards

Are you sure youve got the exact same model as in the thread title. Do you have a copy of the Original backup .

Re: Panasonic CF53 MK4 CF-532S74RMG

Now I try new WLAN Card and still no option/function/Finding

Is it maybe problem with the base (532S74RMG) or the option "2.LAN" that WLAn is not possible?

best regards Mike

Post your original backup, the one before you made any changes to it .

Re: Panasonic CF53 MK4 CF-532S74RMG

hello,

I read and learned a lot here. Many Thanks for that!

Now I'am at the point, that the book is working fine, wireless switch is activated and WWAN detected. WLAN I will change soon, I think it is defect.

I flash with CH341a and clip without any soldering an other bios from here, what in description was free of PW, BUT:

----- just 4 info -----------

I had an PW in the old bios set and I think that was reading out from somewhere in the book, so If I try to enter the BIOS I was not able to go in, because the "data" in bios was clear and the "data" from somewhere not, both missmatch...

I read out my backup from original bios and set the same values inside the new bios and that it works..easy for you but for me something learnd

----------------------------

Now I enable all menu with the "magic string" and have working book..so far so good, BUT:

Question: is it possible to enable ME? I have only "n/a" as info in BIOS and no skills to understand for what is ME usefull, is it problem to work without?

with kind regards

Re: Panasonic CF53 MK4 CF-532S74RMG

hello,

one question: is it possible to flash the bios with AFUWIN or any other tool without external programer? Or if not, is there any tutorial? I have the skills for bonding and using MC's but here I'am newbee

My problem: I have a CF-532S74RMG with bios inside where the WLAN and WWAN function isn't enabled and no option inside the bios to change that.

Maybe you know where I can enable this funktion in the hex-dump?

with kind regards

Re: Panasonic CF53 MK4 CF-532S74RMG

The serial is stored in the ME region in one of the partitions.

yes but search and look just with text 5KTCA or 5JTCA

there are lots of little bits of serial everywhere

the last digits are coded on 16bits little-endian to ascii
look at the number of times found serial on my picture

Re: Panasonic CF53 MK4 CF-532S74RMG

yes but written many times in several ways and I don't know if any checksum to verify.

My original patched file is working fine?

So better to start from an original file and modify it my way if you have other pc to do. You keep the original file like that
