Gayle, I seems that some drives, even from the same mfgr., don't come up to speed quickly enough. I feel studpid for not remembering this sooner. The 7120A doesn't power up until the bridgbeboard begins to boot up. That means the drive doesn't come up to speed by the time the BB starts looking for the hard drive controller, so the controller error pops up because as far as the BB is concerned the controller isn't on line. In fact it isn't, but it soon will be. Unfortunately, that's too late for the boot sequence. The two PCResets actually force a wait on the BB so the boot sequence is delayed just long enough for the drive to come up to speed. My Maxtor 240, on the other hand, powers up as soon as the computer ist turned on. Although I have never tried this with that drive, note that jumper J11 is labeled I/O channel Ready. It is defaulted to OFF. You might try putting a jumper on J11, which turns the I/O channel ON. That may cause the drive to power up earlier and not have to wait until the BB boots. You will be able to tell easily. With the drive exposed to where you can hear it, note that normally the drive will turn on when the BB starts up. You will hear the motor start to come up to speed. If you jumper J11 and the drive comes on immediately after the computer is turned on, then you may not need the PCResets to insert the delays. Steve
