This utility was apparently writen by John Finlay and came to me
|
||
|
|
via Richard Schroeder who got it from Greg Beeley. John, if you want
|
||
|
|
to be credited with your full address or whatever in the Etherboot
|
||
|
|
documentation, please contact me (Etherboot maintainer).

1/18/2000 Marty Connor (mdc@thinguin.org) added code for the 3C905C
|
||
|
|
with AT49BV512 Flash memory, and created cromutil and bromutil to
|
||
|
|
differentiate the versions. cromutil is for 3C905C and bromutil is
|
||
|
|
for 3C905B.
|
||
|
|
|
||
|
|
Be careful. You can easily erase your Flash memory using these
|
||
|
|
utilities. Make *sure* to back them up first using the "read"
|
||
|
|
command. You must "erase" before using "prog" to program the chip with
|
||
|
|
Etherboot code. This code comes with NO WARRANTY, and you take sole
|
||
|
|
responsibility and liability for whatever it does. Read the
|
||
|
|
"romutil.txt" file for more information on commands.
|
||
|
|
|
||
|
|
That being said, if you are programming a 3C905C-TXM (for example)
|
||
|
|
you would do something like this:
|
||
|
|
|
||
|
|
$ cd etherboot-x.x.x/contrib
|
||
|
|
$ tar -zxvf n3c905xutil.tar.gz
|
||
|
|
$ cd n3c905xutil
|
||
|
|
$ make
|
||
|
|
# replace 0x6600 with whatever the IO Addr for your card is!!!!
|
||
|
|
$ ./cromutil 0x6600 read > 905cbackup.bin
|
||
|
|
$ ./cromutil 0x6600 erase
|
||
|
|
$ ./cromutil 0x6600 prog < 3c90x.lzrom
|
||
|
|
|
||
|
|
You should now have an Etherboot-enabled 3c905C-TXM.
