Driver for network chipset 3Com 3C920B-EMB-WNM
Last modified: 2015-01-04 17:08:11 EST
Description of problem: I didn't get the network to work on my ASUS Pundit-R that use the 3Com 3C920B-EMB-WNM chipset. After some detective work I found a soulution on the internet. Re-compiled the kernel and now it is working ok. Version-Release number of selected component (if applicable): I use kernel version 2.6.7 together with Fedora 2 (original kernel has the same problem). The file I have updated is 3c59x.c (file version LK1.1.19 10 Nov 2002). It looks like there are a fix in the driver file for this problem but is not working without my modifications. How reproducible: Use the unmodified/modified driver on a ASUS Pundit-R. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Created attachment 102185 [details] My updated version of the driver file I have only modified two lines in this file.
Created attachment 102186 [details] The original driver file This file is part of linux kernel version 2.6.7
*gna* Anders, could you *please* provide a "diff -Naur" between the original and your modified version? A diff between attachment #102185 [details] and #102186 doesn't show really what's up...so "@@ -1,3156 +1,3156 @@" from the diff I did with your files didn't absolutely help me. All lines are first removed and then added...where's the real change? :)
I did the diff with the attached files and they mess up diff completely (they did pass through a windows machine on the way, thatâs probably why ;-). I have run your suggested command (diff -Naur 3c59x.c.org 3c59x.c) and here is the result: --- 3c59x.c.org 2004-07-12 01:29:17.000000000 +0200 +++ 3c59x.c 2004-07-12 01:34:54.000000000 +0200 @@ -569,7 +569,7 @@ {"3c905B-T4", PCI_USES_IO|PCI_USES_MASTER, IS_CYCLONE|HAS_NWAY|HAS_HWCKSM|EXTRA_PREAMBLE, 128, }, {"3c920B-EMB-WNM Tornado", - PCI_USES_IO|PCI_USES_MASTER, IS_TORNADO|HAS_NWAY|HAS_HWCKSM, 128, }, + PCI_USES_IO|PCI_USES_MASTER, IS_TORNADO|HAS_MII|HAS_HWCKSM, 128, }, {0,}, /* 0 terminated list. */ }; @@ -619,7 +619,7 @@ { 0x10B7, 0x1202, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_3C982B }, { 0x10B7, 0x9056, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_905BT4 }, - { 0x10B7, 0x9210, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_920B_EMB_WNM }, + { 0x10B7, 0x9202, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_920B_EMB_WNM }, {0,} /* 0 terminated list. */ }; .c is the mofified file and .c.org is the original file from kernel 2.6.7.

Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
