Hi,

I have two HP/Compaq TC1100 Tablet PCs, and I'd like to upgrade them to 802.11n by replacing the current mini-PCI card with a TP-Link TL-WN861N card.

I believe that this card uses an Atheros AR5416-AC1A chipset.

The problem is when I install the TP-Link card into the TC1100, I get a "104-Unsupported wireless device" message, and it stops there.

I've been searching for awhile now, and I think that I understand at least some of the alternatives.

Also, I've recently tried flashing the BIOS back to the original TC1100 BIOS, F.03, and still get the same "104" message. In fact, with the F.03 BIOS, it even gave me that message with the original WIFI card, so there's definitely a whitelist, even in the oldest BIOS.

I guess that I'm at the point that I'm ready to look at modifying the device id, etc. in the BIOS to try to get this working.

So, the first thing that I did is run the softpaq .exe for F.0F (the latest BIOS), and found the bios.WPH file.

However, looking at that file using a hex editor, I can't seem to find anything that looks like device id, etc.

So, I was hoping that someone here might help me get started with this.

The latest F.0F BIOS is "sp30961.exe".

And, as I said, when I run that EXE, I get, among other things, a bios.WPH file.

Thanks!

Jim

Hi,

No one has responded, but I hope that someone will, eventually :)...

I have the bios.WPH from the F.0F BIOS. Here's the first part, from a hex editor:

To begin with, I'm not sure if this is compressed or whatever.

I've tried to open it using Phoenix BIOS Editor, and I get "Invalid BIOS length".

Anyone can help with this?

Thanks,
Jim

It is possible to open bios of TC1100 with Phoenix BIOS Editor 2.2.13.
I can share it with you if you do not have it.

I even have TC1100 bios with integrated slic 2.1, somebody in China already moded the bios for "oem activation" of Windows 7. I have this bios too.

Hi !
I tried all that to add my broadcom to the whitelist.
It all looked good, but after flashing my tc1100 now is dead.
I read some methods to boot a phoenix rescue disk from usb but non works, the disk is not booting up.

Does anyone know exactly how to recover my bios / which hotkey to use ?

HELP :-(

Hi greenmk !
I tried following the different methods here(always using the original bios file BIOS.WPH from the F:0F windows upgrade from HP:

http://forums.mydigitallife.info/thread ... procedures

All the procedures want you to start the pc with a specific key-combo, but i cannot get it to work, maybe i am using the wrong combo ?

Can anyone of the pros see from the bios file IF there is a recovery option or if my tc1100 is a paperweight anyways ?


THX,

Ender

P.S. i will post again if i have success, pls do the same...

Hi all
Good news
I have successfully moded white list of my tc1100 tablet. My bios now supports TP-LINK TL-WN 861 N wireless card instead of Intel wm3b2200bg and it is already has slic 2.1 table, so no problem with Windows 7 ultimate “oem” activation. TL-WN 861 N is not the best card for tc1100 - it is too big and I have to isolate it from motherboard and wifi card compartment cover but it is working and tc1100 boots normally. Soon I will describe how I did it. Here you can find my bios:

flash it on your tc1100 on your own risk but it works for me.

Hello Palych,

Can you provide the modded bios that supports TP-LINK TL-WN 861 N because the link you posted is not working anymore?

Many thanks!

Hi,
you obviously have a handle on these TX1100 BIOS(es). I have just acquired a S/H ex corporate unit that has a numeric 8 digit code on the bios entry - indeed on machine entry. Do you have any insights into how to open up the BIOS via a backdoor code or whatever.. Without a BIOS code I guess I may just have a rather pretty paperweight :)

Thanks in advance..

Ken
