Of all the gin joints in all the towns in all the world, Mark Powell had to walk into mine and say: > Installed 2.2-9608101-SNAP on a machine that was previously running > 2.1.5 with no problems.

I can't offer any suggested code fixes (the de driver looks hideously complicated) but you might be able to work around this by using the -link2 option to ifconfig. This will force the driver to enable the BNC connection regardless of what happens with the autosense media probe. I had to do this with FreeBSD 2.1.5 not too long ago. Just edit your /etc/sysconfig file and add -link2 to the ifconfig options for the de0 interface. Ideally there should be a way to specify this information in the kernel config file (or in userconfig for that matter) using a 'flags' option to the de0 declaration so that it selects the BNC connector by default even without intervention from ifconfig. This is not immediately necessary though since it's mostly useful for diskless booting (the ethernet adapter must be configured correctly from the moment the kernel loads) and we don't currently support booting diskless with 'tulip-based' ethernet cards. Note that I habitually disable autosensing even with other OSes such as Windoze NT that have vendor-written drivers. I don't want the machine to tell me what it thinks is the right setting for the card: I want to tell it, and I want it to bloody well listen. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "If you're ever in trouble, go to the CTR.
