Call Debugger During POST
The integrated debugger can be invoked During POST. There are several levels available for
selection:
•
Disabled: Do not invoke the debugger
•
Level 1: Invoke the debugger immediately before boot
•
Level 2: Invoke the debugger before ATA/IDE initializations (includes Level 1)
•
Level 3: Invoke the debugger after VGA initialization (includes Level 1 and 2)
Parallel Port Configuration
The parallel port can be configured by several parameters. If disabled, the settings of the
remaining parameters have no meaning. If enabled, the parallel port IRQ (Level 5/7), address
(278h, 378h, 3BCh), and operation mode (legacy centronics printer, SPP/EPP1.7, ECP/EPP1.7,
SPP, SPP/EPP1.9, ECP, ECP/EPP1.9) can be configured to meet your individual needs.
Serial Port Configuration
The UART COM1/2 ports can be both individually disabled/enabled and configured with respect
to their I/O addresses and IRQ levels. The available addressing range is 220h, 228h, 238h, 2E8h,
2F8h, 338h, 3E8h, 3F8h). You can select either of IRQ 3/4/5/7. If in doubt, select 3F8h IRQ 4 for
UART1 (COM1) and 2F8h IRQ 3 for UART2 (COM2).
