This program was written after playing around with a SONY h, e8 F9 i6 T" c
VAIO notebook trying to find out the Power On Password.

different tricks, I found Jean Delvare's homepage[1] with infos 1 s. A6 u- \6 u7 k+ {) E
about the format of the data stored in the security eeprom. 3 n! W* @$ z i; @+ e7 n
Jean also wrote the eeprom-module[2] for lm-sensors[3] for

should be a utilty called GETSMBUS.EXE to read out SMBus 7 J9 ^) K9 Q" b7 x6 _3 M

I downloaded the package, put the GETSMBUS.EXE onto a
6 v' P- I) v& F7 eFAT32-partition, booted from an old Win98-CD (press F5 at 5 J/ ^3 g1 H. U+ S
CD-ROM-Support-Selection!) and ran GETSMBUS.EXE. It

57.DAT and SMBUS69.DAT. From Jean's homepage I knew - ]$ \0 Z5 k0 D
the address of the security eeprom was 0x57 - so the file

You can use this program to parse the file and extract the
( h, C5 e8 u) h# Iinteresting information. Also the password is decrypted, just in 1 e/ j. S6 d- j$ e# d

2004-03-31: added support for reading out the SMBus directly ! v/ \3 t) ~" b3 O/ F. v0 u
