here it is.. tell either me or jmk@plan9.bell-labs.com if you have
any problems :)
[-- Attachment #2.1: Type: text/plain, Size: 316 bytes --]
The following attachment had content that we can't
prove to be harmless. To avoid possible automatic
execution, we changed the content headers.
The original header was:
Content-Disposition: attachment; filename=ether8139.bundle
Content-Type: text/plain; charset="US-ASCII"
Content-Transfer-Encoding: 7bit
[-- Attachment #2.2: ether8139.bundle.suspect --]

# To unbundle, run this file
echo README
sed 's/.//' >README <<'//GO.SYSIN DD README'
-This bundle contains 3 files:
- README - this file
- ether8139.c.kernel - copy to /sys/src/9/pc
- ether8139.c.9load - copy to /sys/src/boot/pc
-
-To add to the kernel:
- 1) do the above copy;
- 2) edit whatever configuration file you use to add
- ether8139 pci
- in the 'link' section;
- 3) mk
-
-To add to 9load:
- 1) do the above copy;
- 2) add this to /sys/src/boot/pc/ether.c:
- 20a21
- > extern int rtl8139pnp(Ether*);
- 38a40
- > { "RTL8139", rtl8139pnp, },
- 3) add this to /sys/src/boot/pc/mkfile:
- 53a54
- > ether8139.$O\
- 4) mk
-
-The 'type' of the interface for plan9.ini is 'rtl8139', e.g.
- ether0=type=rtl8139
-
-The driver will handle RTL8139 chips which have had the PCI Vendor
-and Device ID changed, e.g. the SMC EZ-Card. There is a table in the
-driver containing (VendorID<<16)|DeviceID to match against. E.g. the
-generic Realtek value is (0x8139<<16)|0x10EC and the SMC EZ-Card is
-(0x1211<<16)|0x1113.
-It is possible to tell the driver to match against a new card not in
-the table by supplying the PCI ID in a plan9.ini option, e.g.
- ether0=type=rtl8139 id=0x813910EC
-If you come across such a card, please let us know so it can be added
-to the internal driver table.

I wrote the instructions in the README file for adding to 9load
based on our current copy of the source. I hadn't realised that the
'ethercards[]' array had moved from load.c to ether.c since the
distribution. So, the instructions should say
To add to 9load:
1) do the above copy;
2) in /sys/src/boot/pc/load.c after
{ "AMD79C970", amd79c970reset, },
add
{ "RTL8139", rtl8139pnp, },
and after
extern int amd79c970reset(Ether*);
add
extern int rtl8139pnp(Ether*);
3) in /sys/src/boot/pc/mkfile after
ether8003.$O\
add
ether8139.$O\
4) mk
Sorry about the confusion.

Heck yea I want it ;)
I don't have the time to finish mine (or should I say the

My favourite chip. I use 8139s everywhere, and it's immensely popular with
manufacturers worldwide. May I commend you on a very good choice of chip to
support. :-)

I have several of cheap cards with this chip, please post a link.

Andrey Mirtchovski <andrey@lanl.gov> and I have finished the
Realtek RTL8139 driver, both system and 9load. If you want the
driver, let us know.
