This procedure is driven by a system configuration table which is processed by .Xr config 8 and compiled into each kernel. .Pp On the .Tn VAX , devices in .Tn NEXUS slots are normally noted, thus memory controllers, .Tn UNIBUS and .Tn MASSBUS adaptors. Devices which are not supported which are found in .Tn NEXUS slots are noted also. The Q-bus, if present, is configured in the same way as the .Tn UNIBUS . .Pp .Tn MASSBUS devices are located by a very deterministic procedure since .Tn MASSBUS space is completely probe-able. If devices exist which are not configured they will be silently ignored; if devices exist of unsupported type they will be noted. .Pp .Tn UNIBUS devices are located by probing to see if their control-status registers respond. If not, they are silently ignored. If the control status register responds but the device cannot be made to interrupt, a diagnostic warning will be printed on the console and the device will not be available to the system. .Pp Normally, the system uses the disk from which it was loaded as the root filesystem. If that is not possible, a generic system will pick its root device as the .Dq best available device .Pf ( Tn MASSBUS disks are better than .Tn SMD UNIBUS disks are better than .Tn RK07 Ns s ; the device must be drive 0 to be considered). If such a system is booted with the .Dv RB_ASKNAME option (see .Xr reboot 2 ) , then the name of the root device is read from the console terminal at boot time, and any available device may be used. .Sh DIAGNOSTICS .Bl -diag .It mba%d at tr%d. A .Tn MASSBUS adapter was found in .Ql tr%d (the .Tn NEXUS slot number). .Ox will call it .Ql mba%d . .Pp .It %d mbas not configured. More .Tn MASSBUS adapters were found on the machine than were declared in the machine configuration; the excess .Tn MASSBUS adapters will not be accessible. .Pp .It uba%d at tr%d. A .Tn UNIBUS or Q-bus adapter was found in .Ql tr%d (the .Tn NEXUS slot number). .Ox will call it .Ql uba%d . .Pp .It dr32 unsupported (at tr %d). A .Tn DR Ns 32 interface was found in a .Tn NEXUS , for which .Ox does not have a driver. .Pp .It ci unsupported (at tr %d). A .Tn CI interface was found in a .Tn NEXUS , for which .Ox does not have a driver. .Pp .It mcr%d at tr%d. A memory controller was found in .Ql tr%d (the .Tn NEXUS slot number). .Ox will call it .Ql mcr%d . .Pp .It 5 mcrs unsupported. .Ox supports only 4 memory controllers per .Tn CPU . .Pp .It mpm unsupported (at tr%d). Multi-port memory is unsupported in the sense that .Ox does not know how to poll it for .Tn ECC errors. .Pp .It %s%d at mba%d drive %d. A tape formatter or a disk was found on the .Tn MASSBUS ; for disks .Ql %s%d will look like .Dq Li hp0 , for tape formatters like .Dq Li ht1 . The drive number comes from the unit plug on the drive or in the .Tn TM formatter .Pf ( Em not on the tape drive; see below). .Pp .It %s%d at %s%d slave %d. (For .Tn MASSBUS devices). Which would look like .Dq Li tu0 at ht0 slave 0 , where .Dq Li tu0 is the name for the tape device and .Dq Li ht0 is the name for the formatter. A tape slave was found on the tape formatter at the indicated drive number (on the front of the tape drive). .Ux will call the device, e.g., .Dq Li tu0 . .Pp .It "%s%d at uba%d csr %o vec %o ipl %x." The device .Ql %s%d , e.g. .Dq Li dz0 was found on .Ql uba%d at control-status register address .Ql \&%o and with device vector .Ql \&%o . The device interrupted at priority level .Ql \&%x . .Pp .It %s%d at uba%d csr %o zero vector. The device did not present a valid interrupt vector, rather presented 0 (a passive release condition) to the adapter. .Pp .It "%s%d at uba%d csr %o didn't interrupt." The device did not interrupt, likely because it is broken, hung, or not the kind of device it is advertised to be. .Pp .It %s%d at %s%d slave %d. (For UNIBUS or Q-bus devices). Which would look like .Dq Li up0 at sc0 slave 0 , where .Dq Li up0 is the name of a disk drive and .Dq Li sc0 is the name of the controller. Analogous to .Tn MASSBUS case. .El .Sh SEE ALSO .Xr intro 4 , .Xr boot_vax 8 , .Xr config 8
