Description shivangp 2001-03-11 04:00:01 UTC 
When I try to install any version of FBSD 4.0 or greater I always get ed1: failed to clear shared memory at 0xc0000 - check configuration. 
I looked it up in the man pages and it says the following:

When the card was probed at system boot time, the ed driver found that it could not clear the card's shared memory. This is most commonly caused by a BIOS extension ROM being configured in the same address space as the ethernet card's shared memory.  Either find the offending card and change its BIOS ROM to be at an address that doesn't conflict, or change the iomem option in the kernel config file so that the card's shared memory is mapped at a non-conflicting address.

I looked for 0xc0000 in system information in windows 98 and I found out that its my video card that has that address. But I tried chaning the video card to an old one but it still did not work. (NOTE: I did not go back into windows to check its location) Do I change the address of my NIC? If so how? If not how do I fix this problem?

1) what kind of card is this?
2) can you show us the contents of /var/run/dmesg.boot?
3) can you show us your kernel config?

Yes, that's the standard starting address for video RAM on a VGA-
compatible graphics adapter in graphics mode (0xb8000 in text mode).
Changing the card won't fix that. I suspect you have a typo in your
kernel config, or your NIC is misconfigured (if it's one of those that
come with a DOS config utility).

BTW, this really belongs on -questions, not in the GNATS database.

Um, what NIC? Include your dmesg(8) output.
