IBM 220 manual Invalid diskette boot record

POST message			Description
602	Invalid diskette boot record.
	Action:	1.	Replace the diskette.
		2.	If the problem persists, make sure that the diskette drive cables are correctly
			and securely connected.
		3.	If the problem remains, replace the diskette drive.
	If the problem persists, call for service.
604	An error occurred during a diskette drive test.
	Action:	1.	Verify that the Configuration/Setup Utility program correctly reflects the type
			of diskette drive that you have installed.
		2.	Run the diagnostic tests. If the diagnostic tests fail, call for service.
662	A diskette drive configuration error occurred.
	Action:	If you removed a diskette drive, make sure that the diskette drive setting is correct
		in the Configuration/Setup Utility program. If the setting is not correct, change it.
	If the problem persists, call for service.
962	A parallel port configuration error occurred.
	Action:	If you changed a hardware option, make sure that the parallel port setting is correct
		in the Configuration/Setup Utility program. If the setting is not correct, change it.
	If the problem persists, call for service.
11xx	An error occurred during the system-board serial port test.
	Action:	If you have a modem, serial printer, or other serial device attached to your server,
		verify that the serial cable is connected correctly. If it is, use the following
		procedure:
		1.	Turn off the server.
		2.	Disconnect the serial cable from the serial port.
		3.	Wait five seconds; then, turn on the server.
	If the POST error message does not reappear, either the serial cable or the device is probably
	failing. See the documentation that comes with the serial device for additional testing
	information.
	If the POST error message reappears, call for service.
1162	The serial port configuration conflicts with another device in the system.
	Action:	1.	Make sure that the IRQ and I/O port assignments needed by the serial port are
			available.
		2.	If all interrupts are being used by adapters, you might need to remove an
			adapter to make an interrupt available to the serial port, or force other adapters
			to share an interrupt.
1800	A PCI adapter has requested a hardware interrupt that is not available.
	Action:	1.	Make sure that the PCI adapter and all other adapters are set correctly in the
			Configuration/Setup Utility program. If the interrupt resource settings are not
			correct, change the settings.
		2.	If all interrupts are being used by other adapters, you might need to remove an
			adapter to make an interrupt available to the PCI adapter, or force other
			adapters to share an interrupt.
