hello everybody!
      I have successfully built clfs based on book clfs-1.1.0 and its running on x86 ULV celeron board.
 However.....
 when i type ifconfig etho does not appear at all onlt the lo:loop back interface comes.
 while booting i get the startup message as eth0 :device does not exist.
 the ethernet driver used in the board is RTL8100BL. i am using kernel 2.6.23-rc2
 anybody has any idea how to make the ethernet work?
 thanking you,
 varrun ashok
 

Quick answer;

Should be supported by the 8139too module (or possibly r8169)...did you
compile the kernel with these modules? Is the module loading? (ie; do  'insmod 8139too'  or
'insmod r8169' -- check output of 'dmesg' for result) If this works, the driver is not autoloading -
did you enable module autoloading during kernel configuration? If you did and it doesn't
auto-load, the device itself might not be referenced by the driver (see below)...if manual
loading works, add the working module name to  /etc/sysconfig/modules...


Long answer;

make sure you have the latest pci-ids file installed

check output of   'lspci -n'  -- find the vid/pid for that device

check linux-2.6.23-rc2/drivers/net/8139too.c (or r8169.c) -- make sure the device vid/pid is listed.

If it isn't listed in the code, send the driver maintainer a note letting them know about the fact
you have a rtl8100bl with an unlisted vid/pid identity


Be aware that it's next to impossible to help you with -your- hardware, if you supply no
hardware specifics....ie; the output of dmesg would be a big help here, and the output
of lspci is also helpful. This is to say, quoting 'rtl8100bl' means very little -- that's just
the model designation, and doesn't reflect the actual chipset/version of chipset used.
