Victor for his unselfish help to laics as I am. Best regards, Janez P.S. Would R24RF08 tool declare some error if el.circuit isn't ok? Back to top victorS.F.

I see there, red, red, black that means 22 ohms. You need red, red, red =2200 ohms. Maybe the picture is to blame but I strongly advice you to check again with an ohmeter to be sure. Don't try unless you are sure you have 2.2Kohms (color code-red,red,red). The rest of colors rep. the tolerance and temperature coefficient Another mention, no need to bridge the pin5 to the COM ground, its already done by the port itself. The table of errors: 1. Circuit unplugged - Circuit not found or bus error. 2. Circuit plugged, eeprom unplugged - eeprom not found (meaning the circuit seems to be good so far) 3. Circuit plugged, eeprom connected - program starts reading. Else one of the first 2 errors displayed.Last edited by victor on Sun Nov 27, 2005 11:21 pm; edited 1 time in total Back to top janezNou VenitJoined: 19 Nov 2005Posts: 3Location: Croatia Posted: Thu Nov 24, 2005 10:16 pm Post subject:

Rzeczywiście hasło było zapisane w małym eepromie na płycie głównej. Opiszę teraz metodę odzyskiwania hasła. Kod: Robicie no na własną odpowiedzialność, nie odpowiadam za szkody wynikłe z użytkowania tego materiału. Teoretycznie działa dla IBM'ów: * 240, 240x * 390E, 390x * 570, 570E * 600e, 600X * 770Z * A20m, A21e, A21m, a22m, A30p, A31, A31p * G40, G41 * R30, R31, R32, R40, R50, R51 * Transnote, T20, T21, T22, T30, T40, T40p, T41, T42, T42p * X20, X21, X22, X23, X24, X30, X31, X40, X41 Pierwsze co należy zrobić to upewnić się, że na płycie głównej komputera znajduje się eeprom ATMEL 24

Dabei bin ich nach diesem Schaltplan vorgegangen: https://www.sparkfun.com/images/tutorials/Beginnin... Im Anhang die Pinbelegung meines ÂľC. Ich hab mich natĂźrlich an die Bezeichnung und nicht an die Pin-Nr gehalten. Das Problem ist, dass meine Software (R24RF08 v2.0b siehe hier:http://www.allservice.ro/store/utils/) "Circuit not found or bus error" sagt und Putty sagt, dass gar nichts verbunden ist. Ich habe bereits getestet, mal rx und tx auf der seriellen und auf der Microcontroller Seite umzudrehen, jedoch ohne Erfolg.
