<20> This Host Adapter may also be ordered with a high-density SCSI-2 <20>
<20> external connector, as part no: 1540B100 or 1542B100. <20>
<20> <20>
<20> SCSI bus terminators MUST be located at each end of the SCSI bus. <20>
<20> If using internal SCSI peripherals only, the terminators on the H.A. <20>
<20> must remain in place, and the device at the farthest point must also <20>
<20> have it's terminators in place. All devices between must have their <20>
<20> terminators removed. If using internal AND external peripherals, <20>
<20> the devices at the end of the internal, and external cables should <20>
<20> retain their terminators, and all those between, including the Host <20>
<20> Adapter, should have theirs removed. <20>
<20> <20>
<20> Adaptec has added support for drives larger than 1GB with their <20>
<20> 3.20 BIOS and uCODE. When correctly set up, the host adapter will <20>
<20> automatically select the correct translation for the drive. The <20>
<20> translation for drives over 1GB increases the heads. <20>
<20> <20>
<20> The 154x series is a Bus Mastering Host Adapter, and is well-suited <20>
<20> for multi-tasking Operating Systems, such as UNIX and OS/2. <20>
