6.0 PGSC-Flight Laptop Configuration Overview
Five configurations have been defined for the PGSC Flight Laptop (all configurations can use
the 3Com Ethernet PCMCIA card):
• Standalone with RS-422 PCMCIA Card
• Docked with PC-Decom AT-Bus and RS-422 PCMCIA Cards
• Docked with OCA AT-Bus Card (Ku and PADM)
• Docked with Proshare AT-Bus and RS-422 PCMCIA Cards
• Docked with RS-422 Sealevel AT-Bus Card
All Serial Devices use either IRQ4 or IRQ3. Standard I/O Address Are Used for COM1 through
COM4. Note: Sealevel Dual Port RS-422 card also uses IRQ10 for second port (set to COM4).
The Mwave Audio Device Uses IRQ5 in all configurations.
The PCMCIA Network Adapter Uses IRQ9 for all configurations.
All AT-Bus Cards Use IRQ10. The SelectaDock I can only house a single AT-Bus card in each
configuration. Note: Sealevel Dual Port RS-422 card also uses IRQ3 for the first port.
All PCI-Related items, including SCSI, use IRQ11.
Primary IDE uses IRQ14 and Secondary IDE uses IRQ15 in all configurations.
IRQ3 and IRQ9 can be used by removing either the RS-422 PCMCIA card or the Ethernet
PCMCIA card, respectively.
The RS-422 PCMCIA card and OCA/PADM cannot be installed on the same PGSC system
due to interrupt and I/O address conflicts.

IRQ 4 - Built-In RS-232 (COM1)
IRQ 5 - MWave Audio
IRQ 6 - Floppy Diskette Controller
IRQ 7 - Parallel Port
IRQ 8 - Real Time Clock
IRQ 9 - 3Com Ethernet
IRQ 10- PC-Decom, OCA (Ku), or Proshare or Sealevel RS-422 Port #2 (COM4)
IRQ 11- PCI (Including SelectaDock I SCSI)
IRQ 12- Trackpoint III
IRQ 13- Math Coprocessor
IRQ 14- HDD / CD-ROM (Primary IDE)
IRQ 15- Secondary IDE
