Hello,
Now my Netgear FA410TXC runs fine!!!
Well, here's the solution:
1- Correct card detection:
The card MAC address is written on the card (Node ID), mine is
00 E0 98 7A F5 61. By default the ed driver doesn't detect the
good type of card and so the correct MAC address.
To fix that we need to modify /usr/src/sys/dev/ed/if_ed.c
at line 1016 (for 4.0R, 1011 for 4.0S) we've got this:
if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {
/* could be either an NE1000 or a Linksys ethernet controller */
linksys = ed_get_Linksys(sc);
replace with:
/* if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {*/
if (1) {
/* could be either an NE1000 or a Linksys ethernet controller */
linksys = ed_get_Linksys(sc);
Rebuild your kernel, now your card must be detect with correct
address and type Linksys (16 bit)
2- Force speed negociation
The card seems unable to negociate link.
I modified the fa_select.c used under linux to fix that pb.
Here's the code for FreeBSD:
/* fa_select.c */
/* modified for FreeBSD 4.x */

}
Don't forget to change #define BASE_ADDR 0x240 with the card address.
To compile it: gcc -Wall fa_select.c -o fa_select
To use it:
fa_select device rate
where device is: ed0, ed1...
rate is: 0 for 10BaseT
1 for 10Base2 (full duplex)
2 for 100BaseT
3 for 100Mbit (full duplex)
I tried this with my adsl modem (Alcatel 1000 Adsl) with 'fa_select ed1 0'
and it runs fine without timeout.
Ok, that's all.
Great thanks for the help to all persons from the mailing list.
