T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
In the last months I've been searching all over internet for an uncorrupted T22 eeprom with no success.
I was wondering if anyone of you have it somewhere on your hard drive and upload it
Or give me some light on how to fix my current eeprom
Thanks.

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
Welcome to thinkpads.com!
Am I to assume that you have a way of re-programming the EEPROM while it's still in circuit, or are you attempting to do this with it removed from the motherboard?

Thanks
Right now I'm using a ghetto SIPROG to dump and write on the eeprom
I've tried to edit my current eeprom by comparing with an uncorrupted eeprom from a Thinkpad A21 but with no success

Worst case scenario you can look up Victor at allservice. I sent in the CRC1 corrupted EEPROM dump of my TransNote to him and he fixed it and sent it back to me. IIRC it was $30.

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
If you truly tried to use an A21 EEPROM dump to revive your T22, then I think that's your problem. I believe that the systems are too different to share BIOS firmware. If on the other hand you meant a T21 image, then I think it's the same issue; BIOS may be incompatible. This is based upon there being different BIOS updates for these 3 systems.
I'll try to look around my home office tomorrow to see if I can find one of my T22 systems. If it still boots, I can get an image off of it that should be able to fix your 0175 error. I've done several such repairs over the years. The method I used is (somewhat) based on what theterminator93 mentioned, requires a US$30 software licensing fee to Victor, some hardware to be built (about US$15 to $20) and another computer that has a serial port. I'll contact you via Private Messages (PM) if I'm able to extract a good T22 image with complete details on how the restoration works.
Please note however that T22 systems are known to be prone to getting the 0175 error. There's no guarantee that your system will not get this error sometime in the future. But if it does, then you'll have a solution that will fix the problem.

I don't get it why theres no eeprom dumps available online, so people can save their old thinkpads for free.
This T22 I have was about to go to the trash by the previous owner, so I took it in, hoping I could revive it with an uncorrupted eeprom.

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
i have a T22
but i dont have any eeprom reading tools, nor knowledge.
isnt there a DOS program that can read the eeprom and make a backup to the c: drive for you?

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
My T22 will not boot (appears to be a dead motherboard). I found a cheap replacement on eBay, but it has 0175/Bad CRC1 error.
I'm contemplating unsoldering the EEPROM from the dead motherboard and putting it in the new system. (at least *attempting* to do so)
But before I do that, I thought I would explore alternatives. For example, could someone read out the contents of the EEPROM if it's in a dead motherboard? Or read it directly from the chip if it's removed from the board?
This thread is a year or so old, so maybe it's old news, but I thought I would check and see if the topic is still of any interest

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
I have a T22 which I got from my employer (it was his old laptop back in the day), which is running spectacularly.
I'll try finding out how to back up the EEPROM from WinFLP, since I do not have enough RAM for Lubuntu (and hence, FlashROM).
Is the EEPROM the BIOS, or something else?

It's the EEPROM dump from the security chip, the Atmel 24RF08.

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
Take out the power, battery and ethernet/modem-card.
Attach only power, try to boot.
If no error, that card was the cause, replace it.
If still error, remove power and also the CMOS battery and RAM.
[Put the keyboard back in and] hold the Power button down for 20 seconds.
Attach only power, try to boot.
It should beep 1-3-3-1 for having no RAM.
If not, your mobo is most likely toast.
If yes, remove power, insert RAM and (a preferably fresh) CMOS battery.
Insert power and try to boot again.
You'll get an error for Date/Time, which needs to be reset in BIOS.
If still Error 175, try to (re)flash the BIOS.
Download the non-diskette version from Drivers link above, burn a CD.
Try to update the BIOS, press F12 if needed to select drive at bootup.
Any luck?
If you load the Atmel dump from another T22, you'll get the wrong Type and S/N, plus a chance for someone else's supervisor password and possibly a tamper-warning.

As to the type, mine is Type 2647, and I see no need for the S/N, so long after these have been released.
Can't we modify the dump to match the OP's hardware?

Re: T22 Error 0175/Bad CRC1. Looking for an eeprom dump.
I think I mixed up moriel5's problem, thought he had error 0175.
If you load someone else's EEPROM, that other EEPROM might have a password!
And virtually every T20/T21/T22/T23 was Type 2647.
A few also did have Type 2648, but they are identical otherwise.

Since I am not having any issues whatsoever, and I know for certain that I have no password saved (I had even disabled some of the security settings in the BIOS, such as IBM's preboot environment).
