Firmware for MJ Tetrad.. Help! I bricked it!

[WS]

Hi Eric,

first, if still possible, don't panic (too much). Has the update
utility by chance created a backup of the old firmware? Or is it
somewhere on a disk with it that came with the instrument? If yes, you
may restore that file hopefully quite easily. Maybe you even can
access a helpful engineer from Biorad or the company they bought the
machine from who can dig out the file you need from the archives.

If not, you need to find someone who is familiar with computer
electronics and someone who own a model as close as possible to yours.
Depending on the situation with the hardware, there might several
options to transplant the firmware from an identical machine, eg by
reading and flashing the EEPROM on an external device. Maybe it's
possible to access the machine's BIOS with sort of terminal program
and issue commands to dump a the firmware from a healthy machine on a
disk an use this for flashing yours.

HTH a bit
