Hi,
Are there any DEC technicians out there who can help me with this
problem?



I have a DEC VT LAN40 terminal. Basically it is a diskless PC from
1994 386sx with 4 MB of RAM and Windows 3.1 from a ROM drive. I can
get into the BIOS setup routine by pressing CTRL-ALT-F1 on boot up but
the machine brings me to a security password screen. I do not have
the password and all the logical guesses for Phoenix BIOS do not work
(PHOENIX, phoenix, BIOS, CMOS, etc)


Here is the interesting part: apparently DEC put the security password
in ROM! I remove the NOVRAM CMOS battery on the motherboard and let
the circuit drain off any excess charge in capacitors I get a message
like "CMOS data corrupted, see service technician". I can clear that
message by letting the BIOS reinitialize the CMOS settings but when I
go to restart, there is the BIOS SETUP password screen again.



Can anyone shed some light on what the DEC VT LAN40 security password
is? This is a legitimate request and I own the computer although it
was used when I got it.



Thanks in advance!
