- "cnet.device" PCMCIA ethernet card driver for A600/A1200
- --------------------------------------------------------
- pre-v1.2 by Bruce Abbott <bhabbott@inhb.co.nz>
- v1.2 - v1.8 by Harry "Piru" Sintonen <sintonen@iki.fi>
-
-
- Introduction:
-
- This is an PCMCIA (aka PC Card) ethernet card SANA2 driver for
- Amiga 600 and Amiga 1200 computers. Most NE2000 compatible cards
- are supported (I hope).
-
-
- Requirements:
-
- - A compatible PCMCIA ethernet card (see the compatibility list).
-
- - An Amiga 1200 or Amiga 600. A1200's need a hardware mod (see
- A1200mod.txt).
-
- - Network software. Tested with Genesis 1.0.6 and MiamiDx 1.0c.
-
- - A network, obviously. :-)
-
-
- Usage:
-
- Four different versions of cnet.device are provided:
-
- - cnet.device.000 - 68000 version, for stock A600s.
- - cnet.device - 68020 version, for 68020+ CPUs.
- - cnet.device.turboio - 68020 version with DMA speedup hack, for
- 68020+ CPUs.
- - cnet.device.debug - 68020 version with debug output to debug
- terminal enabled, use sashimi to capture.
-
- The 68000 version is intended to be used with unexpanded A600. The
- 68020 version is for machines with 68020 or better CPU.
-
- The `turboio' version has a special speedup hack implemented (tech:
- it uses longword access to 16-bit hardware register) that in most
- cases give better performance than the regular 68020 version.
- However some beta testers reported that the regular version is faster.
- Do your own benchmarking to figure out which one is faster for you.
- If you don't care that much about the speed (the speed difference is
- quite minor anyway) then just pick the regular version.
-
- If cnet.device fail to work properly `cnet.device.debug' probably can
- help. It includes full line debug information and has extensive debug
- output to debugging terminal. The output can be captured with sashimi.
- Such sashimi log is recommended when reporting device bugs.
-
-
- Simply copy the preferred version of "cnet.device" to where you want
- it (usually "DEVS:networks/cnet.device") and set up your network
- software for an ethernet driver. For AmiTCP 3.0 this would involve
- editing the "interfaces" file and adding a line like
- "cnet dev = devs:networks/cnet.device". Then you would start it up
- with "ifconfig cnet0 192.168.0.1".
-
- With Genesis and Miami(Dx) setup is really easy, use provided
- installation "wizard" to set up the network. Choose SANA2 type for
- device driver, then choose `DEVS:networks/cnet.device', unit 0.
-
-
- About Netax1200:
-
- Netax1200 card somes with its own driver called `netax.device'. This
- basically is old cnet.device, so Netax1200 users can use cnet.device
- instead.
-
-
- Performance:
-
- My network consists of an A1200 603e+/240MHz/060/50MHz connected via
- coax cable to a P120 laptop. Software on the Amiga is AmigaOS 3.5 +
- Genesis 1.0.6 and on the laptop Debian 2.2. The amiga has Apollo RE450CT
- pcmcia card and the laptop has 3com EtherLink III pcmcia card. FTP
- download from laptop have reached 786Kbytes/Sec. On overclocked 060
- systems speeds of >819Kbytes/Sec have been reported.
-
- <flame>
- Note that Miami and MiamiDx are a lot slower than AmiTCP/IP based
- (Genesis) systems! Nothing can be done to help here, complaints to
- Mr Kruse of nordicglobal <kruse@nordicglobal.com>. And NO I will NOT
- make MNI driver for Miami(Dx) because for some lame excuse MNI devkit
- is kept private! (aargh)
-
- My advice is: use the better protocol stack, Genesis.

-
-
- Limitations:
-
- A1200s require an internal modification to the CreditCardReset line
- to ensure correct card initialisation. If you haven't done this mod,
- you may need to wait until after powering up your A1200 before plugging
- the card in. If the 'Link' LED stays on but you are using coax cable,
- this indicates that the card is NOT working properly. Also, sometimes
- the card can appear to be OK but still doesn't work correctly.
-
- If you don't think you can manage the hack, contact your local amiga
- dealer for plug'n'play PCMCIA-reset-fix -circuit.
-
- NOTE: This hardware mod is not necessarily needed, you can use
- <aminet:util/boot/CardReset.lha> or
- <aminet:util/boot/BK_CardReset.lha> instead.
- Alternatively you can use CardPatch, which should improve card.resource
- even more:
- <aminet:util/boot/CardPatch.lha>.
-
-
- Surf Squirrel Problems:
-
- The Surf Squirrel SCSI/Serial adapter is not a proper PCMCIA card, and
- has no attribute memory. Unfortunately, its driver takes over the PCMCIA
- port and prevents other drivers from owning their cards. This will happen
- whenever squirrelscsi.device is opened, even if the Surf Squirrel card is
- never plugged in!
-
-
- Card_info Diagnostic Tool:
-
- The `card_info' program can be used to identify a PCMCIA card, and
- will display a summary of its attributes. It also produces a binary
- dump of the attribute and I/O memory, which can be analysed for more
- detailed information. `card_info' is quite useful as it can be used to
- find out if the card and the hardware mod work. *However*, just the fact
- that the network card is detected by card_info doesn't yet guarantee it
- would work with cnet.device!
-
-
- Example Network Files:
-
- Because many people seem to have trouble setting up an Ethernet network,
- I have included a copy of my own network configuration and startup script
- files, which you can use as a template for your own installation. Please
- change the username etc. to suit. (These files are by Bruce Abbott
- <bhabbott@inhb.co.nz>, nowadays quite obsolete since both major Amiga
- TCP/IP stacks have installation "wizard")
-
-
- Building:
-
- src directory contains the full source code for cnet.device. You need
- standard make, phxass, phxlnk and os-includes to compile. Everything
- needed excluding os-includes are available on aminet. os-includes are
- available on devcd2.1 for example. After installing make, phxass and
- phxlnk within standard path do the following to compile:
-
- > cd src
- > assign os-include: ADCD_2.1:NDK/NDK_3.5/Include/include_i/
- > make
-
- This results four cnet.device binaries to src directory.

- Legal Mush:
-
- Original note by Bruce Abbott <bhabbott@inhb.co.nz>:

-
- To encourage further development in PC-CARD devices for the Amiga, I am
- placing the source code for this project into the Public Domain. You
- can freely use or abuse it as you wish. I have also included some other
- authors' code for reference purposes, please respect their copyrights.
-
- Please note that this driver is not a finished product, and is almost
- certain to harbour a few bugs. Thus I will not be held responsible for
- any loss or injury that you may incur while using it.
-
- I cannot guarantee compatibility with your system. All I can say is it
- works for me.

-
- Special thanks go to Bruce Abbott for making cnet.device public domain.
- This `legal mush' quote still applies, although I tried to remove as
- many bugs as I could. cnet.device v1.2 - v1.8 are still public domain
- and full source code is included. Enjoy!
