Installing and Configuring Enhanced OS-9
NoteNote
Due to the nature of the ’Symbios_info’ utility changes to the Symbios
driver may cause this program to fail. The ’Symbios_info’ utility should
be re-compiled anytime the driver changes. Although the
’Symbios_info’ utility is mainly used to see how the drive in use is set
up, advanced information is also included to help determine any
problems with using SCSI drives. Most problems with SCSI are
normally termination related. As newer drives become available, we do
expect to see problems that require software related changes.
Syntax
Symbios_info [<opts>]
Options
-s show information
-r show registers
-d show DSP information
-t show time information
Examples
In the basic information mode, Symbios_info displays the interrupt
vector information, the type of Symbios controller found, and the
negotiation information. For synchronous negotiations, the drive
requested time information as well as the actual negotiated time used is
displayed.
