Appendix K
Configuring Devices with SYSGEN (VAX Only)

Devices supplied by HP are attached to the UNIBUS or Q-bus adapters according to the following basic rules:

A device of type A is always at a fixed and predefined control and status register (CSR) address; the device always interrupts at a fixed and predefined vector address; only one example of device A can be configured in each system.
A device of type B is identical to type A except that 1 through n examples can be configured in a single system. Examples 2 through n are also located at fixed and predefined CSRs and vector addresses.
Devices of type C (1 through n of them) are always at fixed and predefined CSR addresses; however, the interrupt vector addresses vary according to what other devices are present on the system.
Devices of type D (1 through n of them) are at CSR addresses and vector addresses that vary according to what other devices are present on the system.

CSR and vector addresses that vary are called floating addresses. The devices must be located in floating CSR and vector space according to the order in which the devices appear in the SYSGEN device table (see Table K-1). The SYSGEN device table lists all the type A and type B devices supported by the operating system. It also lists the type C and type D devices that are recognized by SYSGEN's autoconfiguration procedure.

The base of floating vector space is 300₈. The base of floating CSR space is 760010₈.

K.1 SYSGEN Device Table (VAX Only)

Table K-1 lists the characteristics of all HP devices. This table indicates the following information for each device type:

Device name
Device controller name
Interrupt vector
Number of interrupt vectors per controller
Vector alignment factor
Address of the first device register for each controller recognized by SYSGEN (the first register is usually, but not always, the CSR)
Number of registers per controller
Device driver name
Indication of whether the driver is supported

Devices not listed in Table K-1 are the following ones:

Devices not supplied by HP with fixed CSR and vector addresses. These devices have no effect on autoconfiguration. Customer-built devices should be assigned CSR and vector addresses beyond the floating address space reserved for HP-supplied devices.
HP-supplied floating-vector devices that the AUTOCONFIGURE command does not recognize. Use the CONNECT command to attach these devices to the system.

K.2 Configuring VAXstation 2000 and MicroVAX 2000 Devices (VAX Only)

The System Generation utility (SYSGEN) connects devices, loads their drivers, creates the data structures by which the operating system and drivers coordinate their activities, and calls device initialization routines. In general, SYSGEN is invoked for these purposes late in system initialization during the execution of the system startup command procedure, SYS$SYSTEM:STARTUP.COM.

At that time, STARTUP.COM issues a SYSGEN command AUTOCONFIGURE ALL. SYSGEN's Autoconfigure facility examines its table of possible VAXstation 2000 and MicroVAX 2000 devices (see Table K-2), determines which devices are attached to the system, and configures existing devices using information in the table.

HP strongly recommends that you accept the default behavior of STARTUP.COM. If you must exclude a specific device from being configured, you must first prevent STARTUP.COM from performing the autoconfiguration by setting the SYSBOOT parameter NOAUTOCONFIG. After invoking SYSGEN, you should ensure that the base asynchronous serial ports are always autoconfigured. To do this, enter the following command:

SYSGEN> AUTOCONFIGURE ALL/SELECT=TT:

You can also enter an AUTOCONFIGURE ALL/EXCLUDE=(device-name[,...]) command, making sure not to exclude the serial lines. Subsequent CONNECT statements should be written with the appropriate csr_addr value to the command's /CSR qualifier, as shown in Table K-2. These csr_addr values are actually offsets from the beginning of VAXstation 2000 and MicroVAX 2000 I/O space (EXE$GL_CPUNODSP), thus differing from the customary bus address value traditionally specified for UNIBUS devices in the CONNECT command.
