-= MVME 2300 =-

Hi,

I have some problems using Linux with the MVME 2300.

I'm using the debian potato for Prep (http://www.debian.org/~porter/).
The installation and boot are ok. The problems are  :

1- Universe VME driver.

I have used these drivers :
http://lisa2.physik.uni-bonn.de/~hannappe/software/index.html
http://www.vmelinux.org/

- The first could be loaded but when I'm looking at /dev/vme_stat the
informations are bad (fffffff ...)
- The second don't load and return me an error with PCI_ID

So I had decided to try the MVME2600 kernel image of Gabriel Paubert, this
one don't boot (PC keyb error, there is no keyboard controller on the
mvme2300! ).

Seeing that, I try to compile a new kernel using the kernel patch created by
Gabriel Paubert, and the second second problem appears !

2- SCSI drivers.

I'm using a Technobox 2044 PMC (ncr53c875) as SCSI device.
The kernel provided by Debian see well my SCSI device.

When I want to compile a new kernel using the NCR53c8xx driver, this one
don't  seem to see my SCSI device ( the scsi driver is compiled in the
kernel and not as a module).

The only message I have is :
scsi : 0 hosts.
scsi : detected total.

And I should have that :
...
ncr53c8xx: at PCI bus 0, device 16, function 0
ncr53c8xx: 53c875 detected

...

I had tested differents configurations of the scsi drivers and low SCSI
NCR53c8xx driver : No way !


How can I do to make my MVME 2300 work with Linux ?

Thank's in advance.
