Hi, I had posted earlier to the list about SCSI termination in a Mac IIfx with a newly-installed Jackhammer card. I finally got a hard drive to work with the Jackhammer card by removing the two 8-bit terminator jumpers off the card. I still have a problem. If I hook up an external SCSI device (with or without termination) the system will "see" the external drive but will not boot. If I try to put in a System floppy the computer does not boot up either. This situation exists as long as the Jackhammer card is installed but goes away once removed. With the jumper pins in the card the computer will not bootMy configuration is as follows:
€ Internal drive: 50-pin Seagate Barracuda 2.2 GB (two partions under System 7.1) ID set at 7 by Jackhammer Control Panel with a single SCSI ribbon cable connecting the card to the drive. € 2 Jumper Pins set to TE (Termination Enabled) and another one for termination power FROM the bus. This configuration allows the internal drive to boot up. € Alternatively the second jumper can be set for termination TO the bus and termination FROM the drive. € External HD: LaCie 2.2 SCSI ID 2 with internal termination switch-selectable. As soon as the external cable is connected to the IIfx (with Jackhammer installed) the "SilverLining" indicator appears but the computer fails to go further than that on startup. Termination on or off on the drive makes no difference. So...what am I missing to make this thing work with external devices? Thanks!! -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
