BIOS Operation
This section describes operation with the module's BIOS, and also discusses
module configuration, partitioning, and formatting.
Module Switch Configuration
There are two switch banks on the module which the BIOS reads to config-
ure the SCSI interface, (refer to Tables 3-1, and 3-2). The user will set these
switches to affect SCSI options. Each switch bank has eight individual
switches which can be opened or closed. Configure these switches as de-
scribed in the paragraphs that follow.
SCSI Options
All SCSI options must be determined. These options are the following:
Module Target Number - This is a number from 0 to 7 inclusive. This
number must be unique and is typically defined as 7 for the module
(host).
Parity - Parity disabled will not check parity on the SCSI bus. Parity en-
abled will allow the module to check parity on the SCSI bus. This op-
tion is typically enabled.
Synchronous Negotiation - When this option is enabled, the module will
initiate synchronous negotiations with targets on the SCSI bus. When
this option is disabled, the module will not initiate synchronous negotia-
tions, but will respond to negotiations from other targets. This option is
disabled for older SCSI targets which do not understand synchronous
negotiation protocol. This option is typically enabled.
