Eric, please don't forget that an entire team here at Intel is dedicated to supporting e100 and pro/1000 devices from Intel. Most of the pro/100 features are documented in the SDM which contains some references to the eeprom parts. Mostly the device doesn't need much configuration from the eeprom to work (unlike gigE parts). The SDM can be downloaded from our sf.net project page: http://sourceforge.net/project/showfiles.php?group_id=42302&package_id=68544 The issue that you are reporting: "My system boots fine but when I try to bring up the onboard ethernet (an EEPro 100 VE) I get a "Nobody Cares" message and the interrupt is disabled." However has been recently patched. This should have worked regardless of whether you used e100 or eepro100 (noting that nobody supports eepro100 anymore, you should really use e100 for all tests). if you look in drivers/pci/quirks.c you'll find that there is specific code for e100 devices. If this quirk doesn't work for you then we'll need to dig into that. For this I'd like you to gather: - `ethtool -e eth0` output - `lspci -n` output this will allow me to check the quirck code and see if it has the right device ID. I'm suspecting that the device ID is missing somehow, or the workaround fails. Auke
