how can I have access to the memory as in flat mode?

[Frederic Marmond <fmarmond@eprocess.fr>]

Hi,

few days ago, i posted mails to try to know better about linear memory 
in linux.
perhapse you've already answer me, but I could'nt see mails from the list...
So, I managed to make my prog work by using /dev/mem
it's very ugly, but it worked.

Is there any other way to access somewhere?
In fact the exact problem is:

on a embeded system, the mac-adress of  eth0 and eth1 are stored in a 
flash memory, mapped somewhere.
The 'standard' driver (natsemi) doesn't know this, and try to access to 
the 'normal' pci network card.
So, i have to read the mac adress by hand, and modify the value returned 
by the 'standard' driver.

I know the adress, but I've got seg-faults when trying to access it from 
the driver (readb, (unsigned char*)0xf8000, ...)

any help?

Fred
