2 Workstation Software
WORKSTATION BOOT SEQUENCE
The following procedure describes the Workstation boot sequence that occurs at
Workstation power up:
1. The AT Processor resets and vectors to 386 AMI BIOSTM software. BIOSTM
identifies any Option ROMs and finds the OEC Option PROM on the AT
Communications PCB. The date and version of the Option PROM is displayed
briefly on the left monitor.
2. The CGA video drivers are loaded and the floppy drive is checked (for the presence
of a system boot disk) by the AT Option PROM.
3. The 386 AMI BIOSTM copyright information is displayed briefly on the monitor.
(Award BIOSTM controls information which tells the CPU how and when to access
the disk, read the keyboard, load video drivers, run video screens, etc.)
4. Workstation performs Power On Self Tests (POST). If all internal motherboard
diagnostics pass, the boot sequence continues. If failures occur, the boot sequence
stops at the point of failure and an error message appears on the monitor
5. The AT Communications PCB initializes the Image Processor.
6. The following messages appear briefly on the monitor:
• FASTOPEN installed: This program speeds up disk access time by
keeping track of all files which have been opened.
• NOBRK installed: This program ensures the boot process cannot be
aborted prematurely by the operator and disables NumLock.
• 4FPSTSR installed: This software enables Workstation communications
to the 4FPS or 30FPS disk, if installed. This message does not appear if
the Workstation is not equipped with either of these options.
7. The Image Processor's GSP (Graphics System Processor) software is reloaded.
Both monitors go blank at this point.
8. Front panel/pointing device panel communications are enabled. An audible tone can
be heard from speaker SP1 when this phase of boot up is complete.
9. The Workstation software begins running. The initial Workstation menu appears on
the right monitor when the boot up process is complete.
