Description Nadim Ghaznavi 1999-06-27 21:00:34 UTC
According to the documentation in the source code for the: ewrk3.c : DE203/4/5 : Digital's EtherWORKS NIC In order to use the driver code as a module (which is what the RedHat 6.0 install program does), you must follow 8 steps: ....... (snip -nadim) 0) have a copy of the loadable modules code installed on your system. 1) copy ewrk3.c from the /linux/drivers/net directory to your favourite temporary directory. 2) edit the source code near line 1898 to reflect the I/O address and IRQ you're using. ....... (snip -nadim) Using Tom's Root/Boot Disk, I booted my new system. I then compiled the ewrk3.o module on a different workstation, and moved it to my new system via floppy. I could sucessfully load the modules, and use that network interface (using ping). I found that I could sucessfully repeat this process, but that (as per the documentation in the source code) I had to recompile the module for the specific hardware configuration I had (e.g. with line 1882 set to: 0x260, 10, /* I/O address, IRQ */ -for IO set to 260hex, and IRQ set to 10). Using this mechanism to test my hardware, and the driver, I managed to get two DE205 cards working at the same time, using two copies of the driver, with the appropriate resource (IO address, and IRQ) hard coded into the module's code. I believe this will clearly demonstrate that the IO and IRQ values compiled into the RedHat 6.0 EtherWorks (ewrk3.o) module (on the RedHat 6.0 boot disk image bootnet.img) need to be published to provide support for that NIC.

I'm changing the component to kernel because that's where drivers are compiled.

This issue has been forwarded to a developer for further action.
Comment 3 Cristian Gafton 1999-07-02 21:21:59 UTC
/proc filesystem should be of help with this. Anyway,a ssigned to dledford to see if there is anything we can do.
Comment 4 Nadim Ghaznavi 1999-07-06 02:10:59 UTC
If there's nothing to be done (which is lame, considering all that's required is for someone with access to the source to check line 1882 of the ewrk3.c file, and publish the IO and IRQ), then the DE203/4/5 should be removed from the supported hardware list, since obviously the driver is unusable without knowing what resources it's configured to use.
