That must be the EEPROM. I have a 7958 and the label on the EEPROM is
07958. It would be really great if someone had a ROM listing of this
EEPROM or at least knows where to fill in the geometry of the ESDI disk.
I have one drive that stopped working some time ago and also have a 700 MB
disk left from an old MX300i.
ObTopic...
I just installed the current binary snapshot on an 425T (using remote boot
from Linux to install on the SCSI drive) and so far it seems to work just
fine. All i noticed (but i was not able to duplicate this so far) was that
at some time the "heart beat" LED suddenly reversed its states. I mean it
was switched on all the time and switched off for two short moments
instead of vice vesa... Don=B4t know what happened, but minor glitch...
Everything else looks OK.
Cheers,
Jochen
