When daisy-chaining multiple drives, leave the terminator installed only in the last physical drive on the daisy chain; remove the terminator from each of the other drives. In most PC/AT installations, the C: drive is actually at the end of the cable and should retain the terminator. DA1, DA2, DA3 Drive Address Jumpers The drive address jumpers are identified as DA1, DA2 and DA3. Address selection is binary, as shown in the table below. The ESDI controllers's documentation will specify the drive address to use. Drive Select Jumpers Address DA3 DA2 DA1 ------- --- --- --- 1 out out in 2 out in out 3 out in in 4 in out out 5 in out in 6 in in out 7 in in in "Drive address 0" (no jumper at DA1, DA2, or DA3) is a "deselect" (i.e., no drive selected). Drives are factory configured as Drive Address 1. For many multiple drive installations, each drive must have a unique address. An exception is that for every drive in a PC/AT installation, verify that the only Drive Address is at DA2; move the jumper if necessary(the special twisted interface cable that is generally used takes care of assigning a unique address to each drive). PC/AT controller can typically support a maximum of two drives. W5 Selects the Spindle Control Option. W5 selects the spindle a control option. If W5 is installed, the drive waits for a Start Spindle command(after power is applied) to start the spindle motor. If W5 is not installed (the factory default configuration),the drive automatically starts the spindle motor at power-on. W5 is not installed for PC/AT applications. W1 Selects the Sectoring Mode. If W1 is installed, the drive operates in the soft-sectored mode. If W1 is not installed(the factory default configuration), the drive operates in the hard-sector mode. W1 is not installed for most PC/AT in applications. W2, W3, W4 Sector Size and Number Options The number of bytes per sector may be specified using the Set Bytes Per Sector command or by selecting a default sector configuration with jumpers W2, W3, and W4 as follows: Jumpers Sectors Bytes/Sector W4 W3 W2 Per Track Formatted Unformatted --- --- --- --------- --------- ----------- out out out 53 512 588 ------------------------------------------------------------- | * out out in 54 512 576 | ------------------------------------------------------------- out in out 28 1024 1116 out in in 14 2048 2232 in out out 7 4096 4464 ----------------------- RESERVED ---------------------------- in in out 97 256 321 in in in 1 31,248 31,248 * This is the default (factory installed) configuration and is recommended for PC/AT applications  Micropolis ESDI PCPAK Configuration/Specification Data Sheet Model 1558 1568 1654 1664 Per Drive (MB) 337 676 161 345 Per Sector (B) 512 512 512 512 Sectors/Track 36 54 36 54 Cylinders 1224 1632 1249 1780 Data Heads 15 15 7 7 Form Factor FH FH HH HH Internal Data Transfer Rate(MHZ) 10 15 10 15 Seek Time(msec) (Includes settling) Track-to-Track 4 4 4 4 Average 18 16 16 14 With Multisoft Pc-Kwik 0 0 0 0 Power Dissipation(W) 29 29 15 15 (Drive,typical) MTBF 150,000 150,000 150,000 150,000 The industry's leading,easy to install, complete and fully featured 5 1/4-inch ,high performance, high capacity ESDI-based disk drive add-on/upgrade kits for IBM PC/AT and compatibles.
