Far as I can tell, the UltraBay 2000 is too smart for its own good; it wants to be able to notify the OS that a device has been inserted or removed, and the BIOS complains (that beeping; also, it doesn't really approve of removing a device) if the OS hasn't registered an UltraBay 200 handler of some kind. I don't know if the specs are available from IBM to develop a handler that would make the BIOS happy. -- brandon s. allbery [os/2][linux][solaris][japh] allbery@kf8nh.apk.net system administrator [WAY too many hats] allbery@ece.cmu.edu electrical and computer engineering KF8NH carnegie mellon university ["better check the oblivious first" -ke6sls]
