I should have attached the patch as a text file. My mail program
badly mangled it when I pasted it in. Sorry about that!
If anybody with developer cvs access wants to apply the patch to 5.4
cvs, please go ahead, and update the LOG. Thanks.
It's nice to hear that the patch worked. Have you actually able to
flash some chips on the card? I assume you are using bromutil to do
your flashing, and knowing that it is still working would be nice.
Make sure you stop the ethernet card with something like:
/sbin/ifconfig eth1 down
before you flash it, even if it's not being used for network traffic,
else you may have problems flashing.
Another way to go is with Don Becker's diagnostic programs, available
at:
http://www.scyld.com/ethercard_diag.html#pci-diags
Specifically:
ftp://ftp.scyld.com/pub/diag/vortex-diag.c
You would need to compile with the -DLIBFLASH flag and linked against:
ftp://scyld.com/pub/diag/libflash.c
Don's diag programs are very full-featured, and probably overkill for
your purpose, but they're very informative, and if you have the time
and inclination, they're fun to play with.
We'd enjoy hearing how things go for you, and any notes or comments
you'd like to share about your project. (if you'd like to jot down a
quick HOWTO (nothing fancy, just a list of steps), please do).
