The problem was that for some reason which is not important, there was only
one EEPROM on the board, and was attatched to the first device and it was up
to the driver to work something out. there was a provision for this, and
the majority of multiport NICs went on content with their lives, however a
few were burdoned with the unfortunate co incidence of trying to run the NIC
in one of these aforementioned computers with deranged bioses.
What would happen, is that the ("officially") last network port would be
detected first, and upon discovering there was no EEPROM, the driver would
either squeal or make something up, the last port to be detected should have
been the first and the EEPROM was detected and made of use, so one ended up
with a single working port.
Eventually due to advances in the driver, a reverse probe option was added,
which was brilliant, the board was probed in reverse, and everything was
tickety boo, as Donald continued his driver development, the reverse probe
option was eventually removed, as his new fangled scanning thing did it
automatically (or something like that).
Now, it came to pass that the 2.4 kernel came into existance, and lo and
behold, contained within a "new" tulip driver, one that wouldnt be coujouled
into doing a reverse probe or what ever, so the multiport card is rendered
75% uselsess
Donald has this very nice development driver, which is even worse, under
either 2.2.19 or 2.4.x the driver doesnt work, in that i cant get it to
configure all the ports correctly.
now, all that i want to know, is What on earth has been changed to
COMPLETELY retard what i saw as a usefull card and driver, for my (and other
people), the card is useless, and even worse, so is the damn server its
connected to.
i would be very happy to help in any way i can, let people do what they like
to the driver and test it on this box, because its doing absolutly nothing
at the moment, i would even go as far as to play with the driver my self,
but happen to know sod all about the linux kernel, so i think you will back
me up in thinking that its unwise.
Here is the transcript of an e-mail i sent to Donald Becker on the subject,
and to this date, he has never replyed to it ***, i know he is very busy,
and
seems to not like the 2.4 kernels, so i am not too bothered that my
questions have gone un answered
*** NOTE: this may be due to a missconfiguration in the local mail server,
ignore that paragraph if it is
Thanks guys,
Regards,
Dave
btw, the 2.4 driver works "perfectly" with a non retarded BIOS
