HP 16500B manual Power-Up Screen, Model Number and ROM Version

The Power-Up Routine

When power is applied to the HP 16500B Logic Analysis System mainframe, a series of tasks called the power-up routine is performed to initialize and to verify operation of the mainframe. The mainframe monitor reports the progress and status of the power-up routine. Each of the tasks of the power-up routine is added to the monitor display as the task is being performed.

The following figure shows all of the tasks and possible status reporting fields that can be displayed on the monitor.

The Power-Up Screen

Model Number and ROM Version

The field in the upper right corner of the display shows the mainframe model number and the version of ROM installed on the CPU board. The ROM version number is important because the ROM code must be compatible with the version of the operating system which is stored on the hard disk drive. The ROM and operating system versions are compatible when the operating system version number is the same as or higher than the ROM version number.

"*"

The "*" next to the ROM version number indicates that one of the disk drives is spinning. The "*" only appears when the boot code in ROM accesses a disk drive.
