Dear Victor

I bought a locked IBM T23 on Ebay.
The seller said it was no problem as it was only a supervisor password and he had never needed it. But I flashed to get rid of his boot password and now I can't open the bios or anything. I get "ERROR set time and date" and then the Padlock.

My good husband built your driven circuit (he likes a difficult task) in a
beautiful little box. We got three Pomona clips for the eeprom and every
thing done perfectly. Followed your instructions BUT no result. Here is
a screen shot. I am using another T23 as the 'doctor' machine - is that OK?

He has checked the circuits over and over again. He used an ST232C chip
in the circuit. ITester tests OK I think...

At first he thought the device should be powered with its own battery but then realised not for a soldered eeprom....
have we damaged the Eeprom with too much voltage?? Since then no battery used but still get "Cannot create the file!"[img][img]

Hi Mandy,

The device should be powered all the time, if you reffer the interface.

If the error is "ERROR: Unable to create the file!" then you have a software that is preventing or blocking the disk access. This is very weird, though.

I really need details to be able to help you. Pictures, anything...

Thanks Victor for your quick reply. Will try again with battery power ON. I would like to send a couple of images but don't quite understand how to
upload them to the forum. If I could send them to you by email direct
that would be fine - but you don't publish your address do you?

[Mandy]

Yes both laptops. doctor and locked patient are powered but should we also use battery power in the Eeprom reader.? I have seen on the forum that you said only use the 4.5v battery for unsoldered eeproms. Have I not
understood this?

[victor]

You have to power the interface if you used the driven circuit.

I received the pictures, the setup looks pretty fine, but this doesn't help me, no much details.

The second picture got my attention. Of course it can't create the file:
"r24rf08 a.bin/x/d/i" would try to create a file using forbidden char set.

/x /d /i are swtiches do like this:
r24rf08 a.bin /x /d /i -space between a.bin, /x, /d and /i.

Hopefully that was the only issue there. Good luck, Mandy!

Dearest Darling Victor . You are a wonderful and CLEVER person.
I send you many kisses XXXXXXXX. The T23 has revealed its long
and stupid password to me at last and I am working with the new
laptop after kicking all passwords out of the bios. Husband is very
happy too and says to say he loves you!

Thanks, my sincerely compliments to your hubby.
Lucky guy, eh
