    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.

    What exactly do you mean?
    Original /decompressed bios and mod are exactly 30B6BEh in size.

    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.

    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.

    TTAV134, I'm very impressed. You are very skilled regarding disassembly, thanks for your explanations. Very good work, for me far beyond my knowledge.
    I'll add a mirror link and will create a separate thread which will link to your post, then everybody can find your great mod anytime.

    Thanks.

    No need to be sorry. I just want to figure what causes those 2x5 beeps. :)
    TTAV134 has convinced me that Lenovo probably has integrated a check, probably for sums. He said that if only one byte is changed, the notebook beeps.

    So more tests would be needed.
    I would try to adjust 8 bit sum or additive sum or 16 bit sum.

    Those mods are safe to try since you can use the (unneeded) Id strings to adjust (no code), worst case are 10 beeps...:)
    Another way would be to patch the beep code /check code

    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?

    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. :)
