LENOVO (IBM) Bioses, especially Thinkpad.

Excellent, thanks Yen & TTAV134. Upgrade went smooth, but I'll only be able to test my WWAN card after 1/12/10 when I arrive in Germany. It had it sent to my parents place. Will report back.


Edit:
Since updating I had not shut down the laptop. When I turned the notebook back on I had two series of 5 beeps, but the laptop eventually booted up ok. I turned it off again to verify. Did it again. Since then I have loaded default bios settings and saved newly changed values. Have not rebooted since then. Could that be related to the system looking for some hardware like a WWAN card? I guess I will find out if loading default values fixed it or putting the WWAN card in it when I get my hands on on it. So far does not seem to have any negative impact. Wireless and Bluetooth working fine.

 

thank's for feedback,
2 other users have the same issue (2 x 5 beeps at bootup) on lenovo TC400 here
The patch is the same on these machines, same cause -> same effect, i have now to find a way to eliminate these error bips.

do the beep sequence can be found here

edit1:
something which can be done:
there is 3 patchs, 2 for WWAN and 1 for WLAN.
I can produce for a bios with 1 patch, an other one with 2 and so on.
is there a volounteer for testing this solution.
PM me if you are interesed.



regards

 

I just noticed that the patched bios is 27 Bytes larger than the backup made. Could that be the cause of the beeps?

 

I am going to bed now. I will think about offer of being the guinea pig. Is there a recovery option if something goes wrong with the patched bios like the phoenix crisis recovery for a Thinkpad X201? I always thought there is only one patch for WWAN anf two for WLAN (whitelist and wireless switch).

 

Hi TTAV134,

My post count was not high enough for a PM. from now on I should be fine.
If you know of a safe recovery procedure in case of bricking my notebook (Phoenix Crisis Recovery plus required shortcuts at startup) I am willing to test the WWAN patch.

Thanks

PS: Will still send PM

Edit:
Regarding the beep code. I have not been able to find information about the beep code pattern on any of the bios pages. The HMM only mentions 5 short beeps and blank screen - System Board

 

Well, I had a decompressed .fl1 file which was exactly 27 bytes smaller as the one provided in the patch. My apologies if I have caused any problems anywhere, because verify I just decompressed the original fl1 and the sizes match. May be I had the wrong file somewhere. Sorry.

Sorry. Busy with new family.
Also, whilst my disassembly is not too bad (certainly not skilled) i don't know enough (and can't remember enough) about all the ports used to access IDE/ACHI drives etc.... it would be like looking for a needle in a haystack for me.... even if I knew what the needle looked like.

How i did it:
View attachment 7646 View attachment 7645 View attachment 7647 View attachment 7675

Started 2 years ago, finished now.
At this time i was searching where was the error code ID for 2010 message.
According to the first IDA printscreen of BIOSCOD5 disassembly the code ID for error 1802 is 9Ah and for error 2010 should be A0h, i never found it.
The second printscreen show a call to address 32E0 of BIOSCOD1.
The third printscreen show the subroutine at address 32E0 and 32C4 called each time an error message have to be displayed.
The last printscreen show the portion of code responsible of the error 2010 in BIOSCOD1 module and how to bypass.

End of error 2010 after five years.

regards,

 

Just tried the above BIOS on a 2668 T43 and the 2010 error is gone. The SLIC is inserted and off-line activates with my homemade Lenovo Win 7 Pro disk. Don't have a non-whitelisted WiFi card to try but have no doubt the 1802 error is also gone.

This BIOS is the Holy Grail for T43 users, congratulations. I swear I've looked at every post and never saw this BIOS. I've used several others that worked for activating and 1802 but none had the 2010 error removed.

Thanks.

 

Big day for T43/R52/X41 ThinkPadders! Confirming success also on T43p (2668G1U machine). Cheers

 

Hello guys,

sorry if my question is already answered but i don't want to read over 200 pages I'm looking for a mod BIOS for my Lenovo X200 without Error Message 1802. I want to use another Wireless LAN Card but with original bios a can't. Newest Bios for X200 is 3.15 - ID is 6DET65WW. Could someone post a modified Bios?

 

X200 is easy to patch, a know model. can you refine your request as describe in first page of this thread especialy if your using a SLIC21 already patched bios.

Good job TTAV134. Are you figured out, how the BIOS is checking for approved HDD? I know that this is not neccesary to know now and I am very impressed by your disassembling skills but I am just interesting in this question... Thanks.
