error code to display.
Keyboard / Mouse Tests
Invokes a built-in keyboard self-test of the keyboard's microprocessor and
tests for the presence of a keyboard and for stuck keyboard keys. Test
failure causes an error code to display.
If a mouse is present, invokes a built-in mouse self-test of the mouse's
microprocessor and for stuck mouse buttons. Test failure causes an error
code to display.
If the network board is present, invokes a built-in self-test. Test failure
causes an error code to display.
Tests of Flexible Disk Drive A
Tests for proper operation of the flexible disk controller. Test failure causes
an error code to display.
Coprocessor Tests
Checks for proper operation of the numeric coprocessor part of the
processor. Test failure causes an error code to display.
Communication Port Tests
Tests the integrated parallel port registers, as well as any other parallel
ports. Test failure causes an error code to display.
Tests the integrated serial port registers, as well as any other serial ports.
Test failure causes an error code to display.
Hard Disk Drive Tests
Tests for proper operation of the hard disk controller. Test failure causes an
error code to display. The test does not detect hard disk replacement or
changes in the size of the hard disk.
System Configuration Tests
Initiation of the system generation (SYSGEN) process, which compares the
configuration information stored in the CMOS memory with the actual
system. If a discrepancy is found, an error code will be displayed.
Configures any Plug and Play device detected (either PCI or ISA):
All PCI devices, and any ISA device necessary for loading the operating
system will be configured for use.
Any ISA device that is not required for loading the operating system, will
be initialized (prepared for loading of a device driver), but not fully
configured for use.
