Re: accessing physical mem

[Erez Doron]

well, /dev/mem let me only access real memory, not the adress space of 
the pci cards ....

in the end, i used ltsp to boot from network ( i didn't go that smoothly 
.. )
and I wrote a small kernel driver that looks for the pci card, and makes 
a '/dev/mem'-like char device that lets me access the pci card's memory.

thank you all

hey

I'm looking for a user space tool that can read/write physical adress.
if no such tool exists, tahna maybe a little c program.
any idea ?

Yes, if on IA32 Linux you can use /dev/mem. It's not 100% portable and 
it has certain limitaions but it does the job most of the time.

I'ts not pretty though.
