In those old days,
Done that. Besides: the C-mos config was empty upon arrival. The C-mos battery (3.0 V CR2032) measured at 0.03 Volts :-) I think that caused the whole problem... Together with someone who put a !*&@^#*&[EMAIL PROTECTED] BIOS password on the board. > settings were sometimes stored in a battery backedup (clock) ic. I could have another look, but the first inspection did not result in any DS12XXX or similar 'blocks' found on the board. I estimated that the Intel chipset in combination with the 3-volts button cell did the c-mos storage on this board. > It can also be in a flashprom, you can search for a larger device > with something like 28F.. or 29F... on it. Probably a DIP device. Forgot to mention that: There are 4 eeprom-type devices on the board: - one 24C04 close to the video controller, this would be my 'prime suspect' of holding the password. I have not seen many 24C04-like chips on video controllers (yet..:-) - one 24C16 close to the sound controller, I've seen these chips before on soubdblaster-like cards, i'd expect this one to hold the soundchip(s) configuration - one 93C46 on the on-board LAN controller, seen that before too: usually it holds the MAC address & LAN controller stettings... - the flash BIOS itself (suspect #2, in very close competition with the prime suspect..): unfortunately it's a 28E020 tsop package. Very thin, and very fine-pitched pins. I am confident that i could remove it from the board. I do however not think that there is any way that i could put it back in a way that will result in a working computer :-( These pins are too small for me to solder... > You could try to find another pc and copy their flash using a > standard eprom-programmer.

I can remove the BIOS but not solder it back... This would indeed be my usual approch to this kind of problems, but a tsop package is holding me back this time... > Regards, > Pieter Hoeben > email: [EMAIL PROTECTED] > > Date sent: Thu, 24 Jul 2003 01:09:19 -0800 > To: Multiple recipients of list CHIPDIR-L <CHIPDIR- > [EMAIL PROTECTED]> > Send reply to: [EMAIL PROTECTED] > Organization: Fat City Network Services, San Diego, California > > > A friend donated me an old Fujitsu (now Siemens?)
