The drive has 3 terminating resistors on the bottom of it filling up the holes.
The terminating power source table lists as options: A Drive supplies Own B Drive supplies Bus C Bus suplies Drive Im not sure which way it should be setup, since the IIfx scsi bus isnt the same as the other macs I have (even uses a scsi filter) ----- Original Message ----- From: "res0bznj" <[EMAIL PROTECTED]> To: "Vintage Macs" <[EMAIL PROTECTED]> Sent: Saturday, July 05, 2003 11:26 AM Subject: Re: IIfx and 400mb hard drive > My Reply follows quote.
