.TH SYSDEF 1M .SH NAME sysdef \- system definition .SH SYNOPSIS .B /etc/sysdef [\^opsys\|[\^master\^]\^] .SH DESCRIPTION .I Sysdef\^ analyzes the named operating system file and extracts configuration information. This includes all hardware devices, their addresses, interrupt vectors and unit count, as well as system devices and all tunable parameters. .PP The output of .I sysdef\^ can be used directly by .IR config (1M) to regenerate the appropriate .B low.s .RB ( univec.c on the .SM VAX\*S-11/780) and .B conf.c configuration files. .SH FILES /unix default operating system file .br /etc/master default table for hardware specifications .SH DIAGNOSTICS ``unknown device interrupts at vector xxx'' if information regarding the device cannot be found in the master table. .SH "SEE ALSO" config(1M), master(5). .SH BUGS As yet, .I sysdef\^ knows nothing of devices that are not interrupt driven. .br Because information regarding .I config\^ aliases is not preserved by the system, device names returned might not be accurate.
