YOUH!! Tulip on the hitachi 7850 works now

[tom]

Thanks to a hint from  Olaf Manczak i was able to get the tulip driver
working on the htitachi visionbook pro 7850.
The Problem was not so much related to the driver as to the PCI Bus.
(The hitachi BIOS seems to be a bit broken.)
In the 2.1.107 dev kernel this pci problem was adressed. (i enabled PCI
quirks) After compiling the tulip driver basicaly works now.

Now the device is recognised as rev 30
lspci:
00:0b.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43
(rev 30)

With the old cat /proc/pci its:
  Ethernet controller: DEC DC21142 (rev 48)

i still have problems with Autosense though:

  Media MII,  block type 3.
   MII interface PHY 0 (media type 11).
 MII PHY found at address 17, status 0x782d.
  Internal autonegotiation state is 'Autonegotiation disabled'.
                                                              ^^^^^^^^^^^^^

But this may be due to the fact that the 2.1.107 package includes the 
tulip version = "tulip.c:v0.83". I will play around with newer tulip
versions later, when i got some work done here.
I will update my hitachi page 
http://www.pixelpark.com/~tom/linux/myhitachi.html
over the weekend (hopefully).
  
I just could not wait to tell you the hitachi NIC is working now for me
(boy, am i happy) :-)


cheers
