on — Turns on both low 8 bits and high 8 bits

diff — Places the bus in differential mode

The KZPBA-CB is a Qlogic ISP1040 module, and its termination is determined by the presence or absence of internal termination resistor SIPs RM1-RM8. Therefore, the pk*0_soft_term environment variable has no meaning and it may be ignored.

Example 4–6 shows the use of the show isp console command to display the console environment variables for KZPBA-CBs on an AlphaServer 8x00.

Both Example 4–3 and Example 4–4 show five isp devices; isp0, isp1, isp2, isp3, and isp4. In Example 4–6, the show isp* console command shows isp0, isp1, isp2, isp3, and isp5.

The console code that assigns console environment variables counts every I/O adapter including the KZPAA, which is the device after isp3, and therefore logically isp4 in the numbering scheme. The show isp console command skips over isp4 because the KZPAA is not a QLogic 1020/1040 class module.

Example 4–3 and Example 4–4 show that isp0, isp1, isp2, and isp3 are devices on the internal KFTIA PCI bus and not on a shared SCSI bus. Only isp4, the KZPBA-CB, is on a shared SCSI bus (and the show isp console command displays it as isp5). The other three shared SCSI buses use KZPSA-BBs (Use the show pk* console command to display the KZPSA console environment variables.)
