functionality for the LSI21003 is contained within the LSI53C1010-33. The chip connects directly to the PCI bus and generates timing protocol in compliance with the PCI specification. The PCI interface operates as a 32-bit DMA bus master. The connection is made through edge connector J1 (see Figure 2.1). The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.2 standard. The LSI21003 conforms to the PCI universal signaling environment for a 5 V or 3.3 V PCI b

1.3.3 SCSI Activity LED Interface The SCSI activity LED interface is a four-wire arrangement that allows connection of an LED harness to the board. The connector on the host adapter is J6 for both channels. See Table 3.8 on page 3-12 for the signal name and pin numbers on this interface. 1.3.4 Cabling The cable provided in the kit is matched for a Fast/Ultra/Ultra2/Ultra160 SE or LVD operation. This cable also has built-in multimode (SE/LVD) termination since most Ultra160 hard disk drives are n

A 32-bit slot should be used. The LSI21003 will work in a 64-bit slot, but only 32 bits are used. The host adapter requires a PCI slot that allows bus master operation. See Figure 2.2 on page 2-6. Step 6. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use. Save the bracket screw for securing the installed board. Step 7. Carefully insert edge connector J1 of the host adapter into the PCI slot. Make sure the edge connector is properly aligned bef
