The following figure shows the serial port assignments in the configuration. Table 4. Serial port assignments Port assignment Serial 1 Serial 2 Serial 3 Serial 4 The default setting for the serial port is COM1. Parallel port Integrated in the system board is support for extended capabilities port (ECP), enhanced parallel port (EPP), and standard parallel port (SPP) modes.
• Supports Remote Program Load (RPL) and Dynamic Host Configuration Protocol (DHCP) The PC 300GL personal computer has a 3-pin header on the system board that provides the AUX5 (auxiliary 5 volts) and wake-up signal connections. Real-time clock and CMOS The real-time clock is low-power and provides a time-of-day clock and a calendar.
For information on the connector pin assignments, see “PCI connectors” on page 40. Note: PC 300GL computers do not support ISA expansion adapters or the IBM PCMCIA adapter for PCI. Physical layout The system board might look slightly different from the one shown.
